Which of the following descriptions about branch SNCP protection is wrong?
Which of the following descriptions about branch SNCP protection is wrong?A . When configuring a branch SNCP, you need to set the SNCP subtype.B . The crossover granularity is GE or Any signalC . Trigger conditions are: board not in place, SF, SDD . Branch SNCP protection uses the dual-transmit...
The insertion loss of the 40 split-wave channels of D40 is 6dB. Without considering the influence of noise, when the signal is full, the optical power of the IN port of D40 is X dBm. If the optical power of the IN port is decreases by 1dB, the measured value of one of the output ports is 6dBm. (Assuming that the optical power of each channel is balanced, lg40=16)
