To maximize network performance, and a good fiber cable management system be established. There are four basic principles of good fiber cable management system:<br /><br />1st bending radius limit<br /><br />Fiber bends above the minimum bend radius is signal loss or even the pulp suspension, making a break in service. Today, the industry standards for conventional single-player mode is usually a minimum bend radius of ten times the outer diameter of the cable sheath or 1.5 "(38 mm), whichever is greater, and this new form of flexible single mode optical fiber has the ability to significantly reduce reduce minimum requirements of this curve with a radius of less value, 0.6 "(15 mm), depending on the composition of the cable, without an increase in anesthesia.<br /><br />Reduce the bend radius of the fiber is able to more bends in frames, panels and tours resist. It also increases the reliability of the network and reduces downtime of the network.<br /><br />2nd and clear guide wire<br /><br />The main reason for the fiber optic cable minimum bend radius is a violation of incorrect routing technologies and devices, optical fibers. Routes must be clearly defined and easy to follow. In fact, be so designed that these paths have no other choice than technical route cables correctly. If the option is given to technologies, and avoid contradictory decisions when duties are sending a wrong result, and cause a hole in the radius of curvature. Clear guidance paths, uniform photosynthesis, and training, and less time needed for optical techniques.<br /><br />3rd of easy access to the installation of fiber<br /><br />And offers easy access to the installation of the fiber is essential for maintaining proper bend radius protection. It is a system designed to ensure that the individual fibers can be installed, or easily removed without negative impacts on the surrounding fiber.<br /><br />4th on the Physical Protection of installing fiber<br /><br />Management system must include measures for the physical protection of fiber optic cables with accidental damage to equipment and facilities. Otherwise, the reliability of the network and negatively.Soni Musliminhttp://www.blogger.com/profile/16258838956554993099noreply@blogger.com0tag:blogger.com,1999:blog-8144571111094395351.post-85085604665030190352010-01-08T05:21:00.000+07:002010-01-17T06:53:32.588+07:00Optic Fiber<span class="Apple-style-span" style=" font-weight: bold; font-family:Verdana, sans-serif;font-size:19px;">Fiber Optic ISP T1 Line Internet Connections</span><div><span class="Apple-style-span" style="font-family:Verdana, sans-serif;font-size:6;"><span class="Apple-style-span" style="font-size:19px;"><b><br /></b></span></span></div><div><span class="Apple-style-span" style="font-family:Verdana, sans-serif;font-size:6;"><span class="Apple-style-span" style="font-size:19px;"><b><span class="Apple-style-span" style=" font-weight: normal; color: rgb(75, 75, 75); font-size:13px;"><p style="font-family: Verdana, sans-serif; font-size: 10pt; font-weight: normal; ">A T1 connection is one of the best things for a business to work with.

The fundamental parts of the design are divided into four pieces namely the ferrule, cable, connector housing and coupling tool.</p><p style="font-family: Verdana, sans-serif; font-size: 10pt; font-weight: normal; ">The ferrule operates as a device for aligning the fiber in the total design. It is comprised of a thin cylinder type and is usually produced out of metal, ceramic or plastic items. Next to the ferrule is the cable, the part that offers correct access to the fiber. It is attached to the third component called as the connector housing. The connector housing also connects to the first portion or the ferrule that is linked to the coupling gadget for fiber optic cables. Coupling devices usually come in alignment sleeves and are appropriate in joining connectors.</p><p style="font-family: Verdana, sans-serif; font-size: 10pt; font-weight: normal; ">Fiber optic cable connector special types</p><p style="font-family: Verdana, sans-serif; font-size: 10pt; font-weight: normal; ">The fiber cable connector design listed above is very basic. There are industries that require special connector designs though. One design is identified as the subminiature Type A or SMA. This is one that highlights the ostensible screw-on mechanism. This connector type comes in different designs - some with straight screw connectors while others with smaller connection mechanisms found on either ends of the connector.</p><p style="font-family: Verdana, sans-serif; font-size: 10pt; font-weight: normal; ">An additional kind of connector for fiber optic cables is recognized as the straight-tip or ST connector. This one depends on a bayonet mount lock, a flexible link that can either be separated then refastened with much ease. Of course, the square connector or SC is also highly chosen especially because it prevents crossing of fibers during installation. This one is easily discernible to the user as it has a square tip.</p><p style="font-family: Verdana, sans-serif; font-size: 10pt; font-weight: normal; "></p><p>Visit IndustrialSAVER.com to Buy & Sell Fiber Optic Cables as well as Plastic Materials, </p><p>Plastic Suppliers and other industrial products and services.</p><p><br /></p><p>Article Source: http://EzineArticles.com/?expert=Richard_C._Milton</p><p></p></span>Soni Musliminhttp://www.blogger.com/profile/16258838956554993099noreply@blogger.com0tag:blogger.com,1999:blog-8144571111094395351.post-19033460238416349892010-01-03T05:27:00.001+07:002010-01-15T05:16:23.097+07:00Optic<span class="Apple-style-span" style=" font-weight: bold; font-family:Verdana, sans-serif;font-size:19px;">What is a Fiber Optic Converter and When Do You Need One?</span><div><span class="Apple-style-span" style="font-family:Verdana, sans-serif;font-size:6;"><span class="Apple-style-span" style="font-size:19px;"><b><br /></b></span></span></div><div><span class="Apple-style-span" style="font-family:Verdana, sans-serif;font-size:6;"><span class="Apple-style-span" style="font-size:19px;"><b><span class="Apple-style-span" style=" font-weight: normal; color: rgb(75, 75, 75); font-size:13px;"><div id="body"><p style="font-family: Verdana, sans-serif; font-size: 10pt; font-weight: normal; ">When most people think of serial data converters, they think of RS232, RS422, RS485, TTL, USB and other serial data communication protocols, or perhaps even connections to Ethernet. So where do Fiber Optic converters and adapters come into play?</p><p style="font-family: Verdana, sans-serif; font-size: 10pt; font-weight: normal; ">Fiber optic connections are used in situations where the serial communication protocols' speed and distance limitations interfere with a project. What are some of these limitations? It can be voltage swings, signal interference, electrical surges, or the need for absolute immunity to electromagnetic and radio frequency disturbances. Keep in mind that serial data communication protocols were mostly conceived decades ago when communication speeds were only a very small fraction of what they are today. As a result, while serial communication technologies and standards have proven remarkably adaptable, they were simply never meant to handle some of the complex and super-fast applications they are still being used for today.</p><p style="font-family: Verdana, sans-serif; font-size: 10pt; font-weight: normal; ">In many of those applications, fiber optics is the answer. They use light instead of electrical current to carry signals. These connections provide much higher speed, high bandwidth, and they are inherently immune to radio and electromagnetic interference. This makes fiber optics perfect for serial communication applications that require very high speed or must transfer signals over much longer distances than RS-232, RS-485 or RS-422 can handle, or both.</p><p style="font-family: Verdana, sans-serif; font-size: 10pt; font-weight: normal; ">But aren't these systems too complex for most projects, and aren't copper and optical communication systems incompatible? The answer is "no" to both statements.</p><p style="font-family: Verdana, sans-serif; font-size: 10pt; font-weight: normal; ">As far as technology goes, including fiber optics to a copper-based data communication system requires little more than a transmitter, a receiver, and the fiber optic cable itself. There are some decisions to be made, such as building a single-mode system that uses a single strand of fiber for high-speed long distance communication or a multi-mode system based on less expensive multi-strand fibers. In terms of distance, multi-mode systems can generally extend a serial connection up to about 1.2 miles whereas a single mode system can be used for distances over 12 miles.</p><p style="font-family: Verdana, sans-serif; font-size: 10pt; font-weight: normal; ">As far as converters go, they have come a long way since they were introduced a couple of decades ago. Today's converters are usually auto-sensing, self-adjusting and completely hassle-free. There are no manual settings or switches to figure out, and the converters are hot-pluggable. Fiber optic converters usually come with an external AC/DC power adapter and, depending on the system, may require either SC ("Subscriber Connector") or ST ("Straight Tip") connectors. There are numerous other optical connector types, so make sure you order the right one.</p><p style="font-family: Verdana, sans-serif; font-size: 10pt; font-weight: normal; ">Note that this is not simply a way to "hot-rodding" a slow serial communication system. While optical fibers theoretically can handle almost unlimited speed, the ultimate speed is still determined by whatever RS232/422/485 serial data rate is possible in a system. For serial data communication systems, the maximum data rate is usually around 460kbps. When used in an Ethernet-based system, of course, the converter can easily handle 10BaseT or 100BaseT speeds, and gigabit-capable converters are available as well.</p><p style="font-family: Verdana, sans-serif; font-size: 10pt; font-weight: normal; ">What this all means is that distance is not the limit it once was for serial data communication. Fiber optics can greatly extend serial communication reach, and the required adapters and converters are inexpensive, reliable, and easily available.</p></div><div><table cellpadding="0" cellspacing="0" border="0"><tbody><tr><td valign="top" style="font-family: Verdana, sans-serif; font-size: 10pt; font-weight: normal; "><div id="sig" class="sig" style="font-family: Verdana, sans-serif; font-size: 10pt; color: rgb(75, 75, 75); margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; padding-top: 0px; padding-right: 0px; padding-bottom: 0px; padding-left: 0px; font-weight: normal; "><p style="font-family: Verdana, sans-serif; font-size: 10pt; font-weight: normal; ">Chris Robertson is an author of Majon International, one of the worlds MOST popular internet marketing companies on the web.<br />Learn more about RS422 Converters.</p></div><p style="font-family: Verdana, sans-serif; font-size: 10pt; font-weight: normal; margin-bottom: 1em; ">Article Source: http://Ezinearticles.com/?expert=Chris Robertson</p><p style="font-family: Verdana, sans-serif; font-size: 10pt; font-weight: normal; margin-bottom: 1em; "><br /></p></td></tr></tbody></table></div></span></b></span></span></div>Soni Musliminhttp://www.blogger.com/profile/16258838956554993099noreply@blogger.com0tag:blogger.com,1999:blog-8144571111094395351.post-22026617372960057712010-01-02T04:02:00.000+07:002010-01-14T05:23:30.903+07:00Optics<span class="Apple-style-span" style=" font-weight: bold; font-family:Verdana, sans-serif;font-size:19px;">Is Fiber Optics Better Than Cable?</span><div><span class="Apple-style-span" style="font-family:Verdana, sans-serif;font-size:6;"><span class="Apple-style-span" style="font-size:19px;"><b><br /></b></span></span></div><div><span class="Apple-style-span" style="font-family:Verdana, sans-serif;font-size:6;"><span class="Apple-style-span" style="font-size:19px;"><b><span class="Apple-style-span" style=" font-weight: normal; color: rgb(75, 75, 75); font-size:13px;"><p face="Verdana, sans-serif" size="10pt" style=" font-weight: normal; ">Cable companies have offered access to plenty of cable TV programs as well as internet access. In most households, cable television is a part of our daily lives. We may use cable for telecommunications, entertainment and internet access. It remains as one of the most dominant media out there. Today, however, cable has a new competitor. It’s called fiber optics. And companies such as Verizon are giving cable companies a run for their money.</p><p face="Verdana, sans-serif" size="10pt" style=" font-weight: normal; ">So, what is Fiber Optics? Fiber optics is a medium where light is used to transmit data. With cable and electric forms of transmitting data, you find signals transmitted through copper wires. Data that is in the form of bits (e.g. 0,1) are translated into electrical signals. Because electrical signals are not 100 percent efficient, some of the data gets lost, causing slow downs with transmission rates.</p><p style="font-family: Verdana, sans-serif; font-size: 10pt; font-weight: normal; ">Fiber optics transmits data like cable. Instead of copper wires as being the medium, tubes that transmit light carry the transmission signals. This process is called the internal refraction principle. Because the speed of light is the fastest known entity, fiber optics can clearly surpass other form of mediums.</p><p style="font-family: Verdana, sans-serif; font-size: 10pt; font-weight: normal; ">Fiber optics also has some advantages over cable. Coaxial cable is known for its susceptibility to electromagnetic interference. Since transmission is done through copper wires, the signals could be interfered by other forms of electricity. However, fiber optics is immune to electromagnetic interference because light is used to transmit the data.</p><p style="font-family: Verdana, sans-serif; font-size: 10pt; font-weight: normal; ">There are security issues with coaxial cables. The cables can leak out information due to magnetic fields. Data is not maintained during the transmission. Although there are ways to shield the cables from the magnet interference, cables become less effective. Fiber optics, however, does not have to worry about exposing data. All transmission is funneled through the fiber optic fiber. It doesn’t radiate an electromagnetic field, which makes it impossible to tap into the signal coming from a radiation. This makes fiber optic as one of the most secure medium for data transmission.</p><p style="font-family: Verdana, sans-serif; font-size: 10pt; font-weight: normal; ">Coaxial cables can produce sparks that may be dangerous for any environment. It could cause fires or harm equipment. With fiber optics, there are no sparks or fire hazards because no electricity is transferred in fiber optics. Because of its nature, fiber optics is safe for installation. In fact, you’ll find more flexibility and ease with this medium.</p><p style="font-family: Verdana, sans-serif; font-size: 10pt; font-weight: normal; ">Fiber optics also has an environmental advantage. They can perform at high speeds despite how cold or hot it is outside. This makes the fiber much more consistent and reliable than coaxial cable. Coaxial cable is composed of metals, which can expand or contract during times of heat and cold. Harsh weather can undermine the cable’s performance.</p><p style="font-family: Verdana, sans-serif; font-size: 10pt; font-weight: normal; ">Fiber optics has many advantages over coaxial cable. Although it’s more expensive, fiber optics can give you the broadband speed that you’re looking for. As fiber optics become more available, you’ll see more videos and downloads of programs for the masses. Contact your local fiber optic provider if you’d more information. With blazing access, you can change how you view cable and the internet.</p><p style="font-family: Verdana, sans-serif; font-size: 10pt; font-weight: normal; "><span class="Apple-style-span" style="color: rgb(0, 0, 0); "></span></p><div id="sig" class="sig" style="font-family: Verdana, sans-serif; font-size: 10pt; color: rgb(75, 75, 75); margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; padding-top: 0px; padding-right: 0px; padding-bottom: 0px; padding-left: 0px; font-weight: normal; "><p style="font-family: Verdana, sans-serif; font-size: 10pt; font-weight: normal; ">Michael Russell<br />Your Independent guide to <a target="_new" href="http://cables-guided.com/" style="color: rgb(25, 0, 255); text-decoration: underline; ">Cables</a></p></div><p style="font-family: Verdana, sans-serif; font-size: 10pt; font-weight: normal; margin-bottom: 1em; ">Article Source: <a href="http://ezinearticles.com/?expert=Michael_Russell" style="color: rgb(25, 0, 255); text-decoration: underline; ">http://EzineArticles.com/?expert=Michael_Russell</a></p></span><p></p><p style="font-family: Verdana, sans-serif; font-size: 10pt; font-weight: normal; "><br /></p></b></span><b></b></span></div>Soni Musliminhttp://www.blogger.com/profile/16258838956554993099noreply@blogger.com0tag:blogger.com,1999:blog-8144571111094395351.post-23237956277254687082009-12-13T13:09:00.001+07:002009-12-13T13:09:49.800+07:00Optical<div id="body"> <p>It is said, "Health is wealth". Is it true? Yes surely it is true because weakness of any thing is not appealed by anyone. The reason behind this is that in order to get rid of the weakness, sometimes handsome money is required to cure the weakness. People usually agree to spend for the cure of weakness as there is no alternate way. Eyes are the beautiful gift from God to mankind. If the eye sight weakens, the problem rises in terms of education, working and in many aspects. Thanks to modern science for developing contact lens and optical glass for mankind.</p> <p>It is the invention made earlier than that of contact lens. People with short and long eye sight weakness use contact lens and optical glass which may suite them best. Before the advent of lens, people often wear optical glass but now a day's people wear contacts to make the eyes perfect. Some merits and demerits of contact lens and optical glass must be discussed:</p> <p>Merits of optical Glass.</p> <p>1. It is easy to wear.<br />2. It needs no chemical solution to clean the glass.<br />3. Variety of photo-changing colors can be available.<br />4. Different designs in frames are available to get the glass fit in it.<br />5. Dust particles are not able to flow into eyes easily.</p> <p>Merits of contact lens.</p> <p>1. It is rather difficult to use than optical glass.<br />2. It helps to boost the personality.<br />3. A wide range of colors are available to wear accordingly as desired.<br />4. No need for any frame. But container is given along with the lens to place them after use.<br />5. While working in humid condition lens is the paramount to use.</p> <p>Some disadvantages of optical glass and contact lens.</p> <p>Disadvantage of optical glass.</p> <p>1. It may inconsiderate the personality.<br />2. If a glass of complex number is broken, it may take time in manufacturing.<br />3. Some spots may be present on nose or around ear due to abundant use of the frame.</p> <p>Disadvantage of contact lens.</p> <p>1. Hard contact lens may irritate eyes and may give woozy vision.<br />2. Dust may directly reside on the lens.<br />3. A chemical solution is required to protect the lens after use.</p> <p>Optical glasses are available in various frame designs and also in various photo sun glasses. There are usually three common types of color in optical glass.</p> <p>1. Photo brown sun glass.<br />2. Photo black sun glass.<br />3. Plain sun glass.</p> <p>These photo sun glasses change the color of glass with the intensity of sunlight. Qualities are available in such photo color glasses. Best quality must be selected to make sure the best result with long life.</p> <p>Contact lenses are available in wide range than that of optical glass.</p> <p>1. Hard contact lens have non flexible material with number of demerits<br />2. Daily disposal lens are used for a day and require no cleaning.<br />3. Silicone wear lens are less irritating and another type of contact lens.</p> <p>Polycarbonate and Plastic are less expensive material for optic option while contact lenses are often expensive.</p></div> <div sizcache="1" sizset="80"> <table cellspacing="0" cellpadding="0" border="0" sizcache="1" sizset="80"> <tbody sizcache="1" sizset="80"> <tr sizcache="1" sizset="80"> <td valign="top" sizcache="1" sizset="80"> <div class="sig" id="sig" sizcache="1" sizset="80"> <p sizcache="1" sizset="80">Do visit Irsan's latest website at <a href="http://www.portablekeroseneheater.org/" target="_new" jquery1260781620468="12">http://www.portablekeroseneheater.org</a> which contains reviews and deals on <a href="http://www.portablekeroseneheater.org/" target="_new" jquery1260781620468="13">Portable Kerosene Heater</a> and other information about electric heaters.</p></div></td></tr></tbody></table></div>Soni Musliminhttp://www.blogger.com/profile/16258838956554993099noreply@blogger.com0tag:blogger.com,1999:blog-8144571111094395351.post-39258740409789942412009-03-11T07:55:00.000+07:002009-03-11T07:58:09.510+07:00A Dissecting Microscope For School UseAnyone who has taken high school biology has encountered a dissecting microscope; it was usually accompanied by a frog. The trauma involved in having to chloroform destroy a frog in the name of education may, however, have rendered you oblivious to the workings of the dissecting microscope, so here is a refresher course on how it was constructed and how it worked.<br />Construction Of A Dissecting Microscope<br />The dissecting microscope, like all microscopes, has a tube with a lens at its upper opening, through which you look to view the specimen lying beneath the tube’s lower end. The upper end of the tube will also have some form of nose piece to help your head remain steady while you do your viewing.<br />The lower end of the dissecting microscope contains the second lens, known as the “objective“ lens. The type of objective lens being used will depend on how fine a focus you need to examine your specimen. Your dissecting microscope will have two more light-condensing lenses in its condenser; these lenses are responsible for the microscope’s magnification capacity.<br />The dissecting microscope’s condenser is centered above the middle of the microscope’s stage, on which the slide bearing the specimen ifs placed for examination. The best dissecting microscopes have adjustable stages which can be manipulated without the microscope’s user having to remove his or her eyes from the eyepiece.<br />The <a id="link_83" href="http://www.microscopesreview.com/Articles/Stereo_Zoom_Microscope.php" target="_new" rel="nofollow">dissecting microscope’s stage</a> is positioned above its diaphragm, the function of which is to control the amount of light being transmitted through the slide and specimen. The light itself is also below the dissecting microscope’s stage, and is either a halogen or fluorescent bulb. It is the manipulation of the light’s reflection on the specimen that causes the dissecting microscope to magnify what the user sees.<br />Caring For A Dissecting Microscope<br />Dissecting microscopes, like all others, require special care; their lenses should be kept dust and smudge free with dry, soft cloths and they should be stored, when not in use, in dust covers. They should also be stored away from dampness.<br />Those handling a dissecting microscope should always carry it in both hands. That is the best way to avoid either dropping it or bumping it against other objects; either of which will ruin the alignment of the lenses. The dissecting microscope is most secure when its user holds the microscope arm in one hand and supports its base in the other.<br />You can also find more info on <a id="link_84" href="http://www.microscopesreview.com/Articles/Microscope_Slide.php" target="_new">Microscope Slide</a> and <a id="link_85" href="http://www.microscopesreview.com/Articles/Stereo_Zoom_Microscope.php" target="_new">Stereo Zoom Microscope</a>.

Two kinds of lenses are used ? eyepiece lens (ocular) and the objective lens. Both the lenses are connected using the tube. The place where the viewing object is placed is called the stage. The arm connects the stage and the lens. A microscope has two adjustment knobs, which help to focus the lenses.<br />How does a microscope work?<br />The object or the specimen is kept close to the objective lens, so that the light from it focuses around 160 mm inside the microscope. This creates an enlarged and inverted image of the object. The image is then directed straight into the eye with the help of the ocular or the eyepiece.<br />How to use a microscope?<br />Place the specimen on the microscope stage and fix it with stage clips. Turn the coarse focus knob to bring the objective lens close to the specimen. Then, adjust the illuminator and diaphragm by looking through the eyepiece. Slowly turn the adjustment knob, until the image is focused.<br />What are the different types of microscopes?<br />Basically, there are three types of microscopes: electron, confocal, and compound. Electron microscopes are sophisticated magnifying devices using a high energetic beam of electrons. They can be further classified as scanning electron microscope (SEM) and transmission electron microscope (TEM). The confocal microscopes use a laser beam to illuminate the objects. Compound microscopes are the simplest type of microscopes. In this, the object or the specimen is illuminated using bulb light or light from the sun. Depending on specific applications, you can choose from portable student microscopes, surgical microscopes, metallurgical microscopes, measuring microscopes and industrial microscopes.<br /><a id="link_87" href="http://www.wetpluto.com/Essential-Parts-of-a-Microscope.html" target="_new">Microscopes</a> provides detailed information on Microscopes, Electron Microscopes, Parts of a Microscope, Compound Microscopes and more.

In the passing centuries, microscopes evolved into powerful, precise tools that allow scientists to view tiny objects at a level of detail that seems unreal. There are a wide array of available microscopes, from the compound microscopes commonly found in high school science classrooms to powerful scanning tunneling and electron microscopes used by Nobel Prize winners.<br />Most historians agree that two Dutchman made the first microscope in 1590. Zaccharias Janssen and his son Hans were two eyeglass makers who experimented with putting multiple lenses together in a tube. They found that objects under the tube were greatly enlarged. Over the next hundred years, scientists Robert Hooke, Anton van Leeuwenhoek, and others further refined the work of the Janssens and used microscopes to examine insects, blood, and other items. Scientists have continued microscopes into the present day. Now, microscopes can show tiny particles that are unseen by the naked eye in extremely exact detail.<br />Microscopes operate on several principles. Most common microscopes have two different lenses. Viewers look through the ocular lens, also known as the eyepiece. There is another lens, called the objective lens at the end of the ocular lens. The objective lens is a sphere shaped lens located above the stage of the microscope. People place the object they want to examine on the stage and can adjust the lenses to bring the object into focus. Most microscopes have an adjustment knob for coarse focus and one for fine focus. Many microscopes have several objective lenses with different strengths for users to choose from. The lenses are arranged on a circular platform that can be rotated to have the different lenses put into place under the ocular lens. Microscopes also need a light source of some kind underneath the stage. Most commercial microscopes have a light bulb, but many high-end microscopes use lasers or electrons for illumination.<br />Microscopes have been used to make countless vital scientific discoveries. They are invaluable tools used in a variety of scientific fields that enable researchers to make discoveries that would be impossible with the naked eye.<br /><a id="link_82" href="http://www.wetpluto.com/Essential-Parts-of-a-Microscope.html" target="_new">Microscopes Info</a> provides detailed information about electron, compound, stereo, digital, video, and scanning tunneling microscopes, as well as an explanation of the different parts of a microscope, and more.
