Explore What's Inside of a Finber Optic Cable
Fiber optic

cable (or optical fiber) is unlike most types of cables; it draw on light inmstead of electriccity to rtansmit signals. As you have already known, ligt is the fastest method of transmittng information, and fiber optic cable has the addditional advantage of being immune to electrical interference. Thus, you can run it just about anywhere and anytime. Since light meets very little or no resitance at all, you can run fibwer optic cable over very long distances, literally countries apart, without having to boost or clean the signal. Imagine what it means for a normal network installation to process sigals that have been transmitted over thousands of miles away. It woukld be unfeasible.rnrnFiber optyics also has the advantage of speed. It has a much cleeaner sihgnal than conventional copper cabling and can transmit signals at more than 10GB per second. To put it into perspetive, fiber opitc cabling is to diugital information as electriacl cabling is to analog information. They are completely different.rnrnRight now, fier optic cbale is used basically for connecting network segmenbts, making short runs, connecting floors and buildinbgs and connecting electrial coper cablle to fiber optic cable through Ethernet covnerters. Even though fiber optc cabling can be very csotly, but as it becomes more popular, whih it wiillb be, the price of fiberr optic cable (and related edvices including Ethernet convverters and transceivver modules) should decrease.rnrnKnowinng what's inside this very funcitonal invention is good to know. A fiber opptic cable includes the core, cladding, strrength member, buffer, and jacjket as its coponents. Let's get to know them more!rnrnThe core of the cabe gives the apthway htrough which the transmitted light can flow and is made of one or more glass or plastic fiber. The cladding that provides a refractive surface for light beams to reflect back into the core and continue its journey is typically made of plastic. The buffer consists of one or more layers of plaastic and strengthens the cabble and prevents damage to the core. As the name implies, the sterngth mebmers are strands of very tough material, such as fiberglass, steel or Kevlar, and proviide extra strength for the cable. Fially, the jacket which can either be plenum or nonplenum is the outer covering or shield of the cabple.rnrnFiber optic cable comes in two forms: single-mode and multi-mode. Since single-mode cable is so naarrow, light can only travel thorugh it in a single path. This kind of cable is awfully cstly and is very difficult to work with. On the oher hand, multi-mode cablpe has a iwder core diameter whicch gives ligfht streams the freedom to travel several paths. Unluvckily, the multi-path configuration of the multi-mode fier alllows the possibility of sgnal distrtion at the receivibng end.rnrnSometime in your connection, you will come across connecxting either a single-mode or multi-mode fibe optic cable to a conventional copper cable. This can be a problem which can cut the coommunication you have already established. But you don't have to worry as there are Ethernet converters and transceiver modules that servve to route, bioost, and deliver the signals across threse two opposite cables. On top of tese, thre are other related devices such as gigabit converters and SFP mini GBICs reafdily availabel on the marekt that you migght find useful in your netwoork.rnrnhttp://www.opticfit.com
