1、 When G.652C and G.652D optical fibers are used, the maximum information transmission capacity is:
1. 2Mbt/s (broadband) port: 10.36 million can be transmitted.
2. Telephone circuit: 310 million can be transmitted.
3. At the same time, there are 310 million pairs of people for dialogue between the two places.
2、 The maximum information transmission capacity of photonic crystal fiber is:
1. 2Mbt/s (broadband) port: 20.62 million can be transmitted.
2. Telephone circuit: 610 million can be transmitted.
3. At the same time, there are 610 million pairs of people for dialogue between the two places.
If the transmission code speed is increased or the wavelet division interval is reduced, the maximum amount of information transmission can be doubled.
Extended data:
The transmission loss characteristic of optical fiber is one of the most important factors that determine the transmission distance, transmission stability and reliability of optical network. There are many reasons for the loss of optical fiber transmission. In the construction and maintenance of optical fiber communication network, the most noteworthy is the reason for the loss of optical fiber transmission in use and how to reduce these losses.
The transmission loss caused by the use of optical fiber mainly includes connection loss (inherent loss, fusion loss and movable joint loss of optical fiber) and non connection loss (bending loss and loss caused by other construction factors and application environment).
