Fiber optic cable bandwidth

Introduction : 

In general, bandwidth is referred to as the range of a particular fiber optic cable. In reality, different cable has a different bandwidth capacity of transmitting data from one point to another. The bandwidth of fiber optic cable determines the maximum speed of the data pulses to the fiber cable can handle it. We know that the bandwidth is normally stated in terms of megahertz-kilometers.  For instance, there those which are most suitable is carrying large quantity data over long distances within a short time. Consequently, there are those most suited in transmitting a large quantity of data over short distances. In this case, the cable made to transmit data over very long distance cannot be used to transmit the same data over a short distance and if that is done, then the frequency will too much lower. For that reason, it is very important to study that bandwidth of particular fiber optic cable.

As the length of the fiber cable is increased, the bandwidth decreases in propagation. In general, a common 62.5/125 micrometer cable has a bandwidth in the 100 to 300 MHz-km range.

The speed of optical fiber cable while in using a single mode fiber cable can run from a few meters to 40 kilometers Where a multimode fiber optic cable is used for much shorter ranges.

Fiber types and bandwidth  :

Single mode - 100 Ghz-km
Graded index - 560 MHz-km at 1300 nm, 160 MHz-km at 850 nm 
Step index - 20 MHz-km

Conclusion :

The cost of fiber cables with the bandwidth capacity of fiber optic cable. You can have also found that fiber cable with efficiently and faster bandwidth capacity is more expensive than others. The greater the frequency and larger the bandwidth of fiber optic cable the more efficient is the cable. So and we already know that different people have got different reasons to purchase a fiber cable, the variation of bandwidth has indeed been beneficial to many. Therefore, the bandwidth capacity of fiber optic cable before purchasing it.
