Which of the following functions are not available in PW OAM?
The insertion loss of the 40 sub-wavelength channels of D40 is 6dB, regardless of the influence of noise, when the signal is full-wave, the IN port optical power of D40 is X dBm. If the optical power of the IN port is reduced by 1dB, The measured value is () dBm. (Assuming that the optical power of each channel is balanced, lg40=1.6)
When congestion occurs, queuing strategies can be varied. If you need to take service for the messages that arrive first, you can use the () queuing strategy; if you want to ensure that the most urgent and critical services are served first, you can use the () queuing strategy; if you need to balance the delay and delay jitter of each stream, You can choose () queuing strategy; if you want to provide professional bandwidth for a specific business, you can choose () queuing strategy.
