can use a 1 * N switch to connect multiple optical fibers to an OTDR ). Monitors Optical Fiber Links. Vswitches and OTDR can be used to accurately locate faults on each fiber link. In the actual transmission network, the switch also allows the user to take out the signal or draw a network analyzer for elbow monitoring without interfering with network data transmission. Optical switches can also be used for field testing of Optical Fiber

Recode Chinese station August 25 reportEveryone believes that mobile technology will be the future of the digital industry.

to achieve selective wavelength insertion. In this kind of OADM, some new functions can also be displayed by adding components such as a variable attenuation and a photon detector. In a DWDM network, OXC can provide a dynamic exchange connection between the input and output of M * N optical fiber. In this way, the optical crossover switch can provide one-to-multiple connections without blocking in matrix configuration. OXC can improve network viability, reduce network management costs, and re-c
