The Difference Between Fiber Optics and Optical Fiber ?

Brief Introduction
It is a technology that uses glass (or plastic) threads (fibers) to transmit data. A fiber optic cable consists of a bundle of glass threads, each of which is capable of transmitting messages modulated onto light waves. It is a hair-like glass conduit that carries virtually any type of signal from one point to another at light speed. Unlike copper based signals, fiber signals are not affected by external power sources or surges and there is no need for shielding or grounding.


Advantages
Fiber optics has several advantages over traditional metal communications lines:
*transmit more info with greater fidelity over longer distances
*added security, more resistant to electrical interference than traditional cooper cabling
*Fiber optic cables are much thinner and lighter than metal wires.
*Data can be transmitted digitally (the natural form for computer data) rather than analogically.

The main disadvantage of fiber optics is that the cables are expensive to install. In addition, they are more fragile than wire and are difficult to splice. While fiber has the disadvantage of requiring more expensive equipment and training, the extra expenses are well worth the monumental gains in speed and efficiency.

Fiber is the world's most difficult cable to terminate. Optical fibers must be finely cut, cleaned, polished, and inspected to ensure performance. Infiberone feature a huge selection of fiber termination kits, cleavers, testing and cleaning supplies.

Application
As optical fiber is more effective than cable, a lot of Internet, telephone systems and cable TV occasions use fibers. Fiber optic cable allows network builders to divide their network into smaller service areas that prevent large numbers of customers from being affected in an outage. The result is better service and customer relations. Fiber optic cable also gives them a fast return path which they use for internet and telephone connections, thereby increasing their revenue potential.
