Fiber_Optic_Cable

Fiber Optic Cable Fiber Optic Cable Fiber optic cabling consists of a centre glass core surrounded by several layers of protective materials (See fig. 5). It transmits light rather than electronic signals eliminating the problem of electrical interference. This makes it ideal for certain environments that contain a large amount of electrical interference. It has also made it the standard for connecting networks between buildings, due to its immunity to the effects of moisture and lighting. Fiber optic cable has the ability to transmit signals over much longer distances than coaxial and twisted pair. It also has the capability to carry information at vastly greater speeds. This capacity broadens communication possibilities to include services such as video conferencing and interactive services. The cost of fiber optic cabling is comparable to copper cabling; however, it is more difficult to install and modify. 10BaseF refers to the specifications for fiber optic cable carrying Ethernet signals. Facts about fiber optic cables: •Outer insulating jacket is made of Teflon or PVC. •Kevlar fiber helps to strengthen the cable and prevent breakage. •A plastic coating is used to cushion the fiber centre. •Centre (core) is made of glass or plastic fibers. Fiber Optic Connector The most common connector used with fiber optic cable is an ST connector. It is barrel shaped, similar to a BNC connector. A newer connector, the SC, is becoming more popular. It has a squared face and is easier to connect in a confined space. About the author: Gianfranco Fracassi is the webmaster of two popular free stuff web sites.
