What is OLA and REG Signal Flow Overview about?

This document discusses wavelength division multiplexing (WDM) sites and provides details on optical line amplifier (OLA) and regenerator (REG) topologies and their signal flows. The OLA amplifies bi-directionally transmitted optical signals to extend transmission distances. The REG regenerates each wavelength by converting it to electrical, regenerating it, and then converting it back to optical. Regeneration is needed every 80 wavelengths to reshape and reduce jitter and noise in the signal.
