ESC can also be used at OLA sites.
Which of the following statements about the modulation technologies of the 40Gbit/s and 100Gbit/s coherent systems are correct?
In a WDM system, after a distance of transmission, the OSNR of the signals at the receive end decreases to a certain extend. Which of the following is the main cause?
Which of the following ROADM boards have WSS optical modules? (Choose two.)
Which of the following is the client-side logical port of a board in standard mode?
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.
