What is the impact of roll-off factor in Nyquist WDM?

24 August 2018 0 1K Report

Consider a Nyquist-WDM system using M-ary raised cosine pulses to modulate the optical carrier. What would be the impact of the different roll-off factor values in the data rate and transmission distances of the system? Also, give practical considerations regarding this roll-off factor.

With regards,
