Advantages and disadvantages of optical fiber communication What are the advantages and disadvantages of optical fiber communication?

1, advantages:

(1) has large communication capacity and long transmission distance; The potential bandwidth of optical fiber can reach 20 Hz.

(2) Anti-electromagnetic interference and good transmission quality. Electric communication can't solve all kinds of electromagnetic interference problems. Only optical fiber communication is free from all kinds of electromagnetic interference.

(3) The optical fiber is small in size and light in weight, which is convenient for laying and transportation;

(4) The raw materials are rich in sources and have good environmental protection, which is beneficial to saving nonferrous metal copper.

(5) Without radiation, it is difficult to eavesdrop, because the light wave transmitted by optical fiber cannot run out of the optical fiber.

(6) The optical cable has strong adaptability and long service life.

2. Disadvantages:

(1) is brittle and has poor mechanical strength.

(2) The cutting and splicing of optical fibers need certain tools, equipment and technology.

(3) The shunt and coupling are not flexible.

(4) The bending radius of optical cable should not be too small (>; 20 cm).

(5) Power supply is difficult.
