Abstract :
Adaptive optical transceivers are considered among the candidates for future optical communications, especially in long-haul and metro applications. In this paper, the hardware requirements of the adaptive digital coherent transceivers are studied. Challenges and solutions for power-efficient implementation of the electro-optical front-end and digital signal processor are investigated. Different power-saving modes are also presented.
