Which of the following statements about the Service Package is incorrect?
The maximum output optical power of an OBU board is 20 dBm, when it is used in a C-band 80-channel system, what is the standard per-channel output optical power?
Before the optical power commissioning of an ROADM board, you need to configure virtual optical-layer services. Otherwise, the ROADM board blocks all wavelengths by default.
Which of the following residual dispersion values are within the dispersion tolerance of the TN52ND2 board?
Which of the following is approximately equal to 100mw?
Dispersion compensation is not required for 40Gbit/s and 100 Gbit/s coherent systems because the dispersion tolerance of coherent boards is large. NG WDM products do not support hybrid transmission of non-coherent and coherent networks.
