Advantages and disadvantages of optical fiber communication

Advantages and disadvantages of optical fiber communication

Answer:

To say the fault, depends on who compares, the shortcoming is opposite.The most obvious is the estimation of maintenance problems, for example, the cable is broken, as long as the simple connecting line, broken several times are no problem, but a different cable, can have a few kilometers on contact is strictly index, mainly because the cable is relatively fragile, slightly smaller bending radius will bring almost interrupt
Optical fiber communication has the following disadvantages:(1) the bending radius of optical fiber should not be too small;(2) the operation of optical fiber cutting and connecting is complicated;(3) trouble of shunting and coupling.
Compared with cable or microwave, the advantages of optical fiber communication are as follows:(1) the transmission band is very wide and the communication capacity is very large;(2) because of the small attenuation of optical fiber and no relay equipment, the transmission distance is far;(3) crosstalk is small and signal transmission quality is high;(4) optical fiber anti electromagnetic interference, good security;(5) optical fiber is small in size and light in weight, easy for transmission and laying;(6) resistance to chemical corrosion;(7) the optical fiber is drawn by quartz glass, the raw material is abundant, and a large amount of nonferrous metal is saved.
