Abstract:
WDM-PON based on low-cost tunable lasers is a promising candidate for next-generation broadband optical access. For cost reasons, the tunable lasers must not be equipped with dedicated coolers and wavelength lockers. Then, correct tuning of the lasers must be ensured by cost-effective tuning mechanisms which are implemented and shared in the system context. In this paper, we describe several approaches to WDM-PON and how wavelength locking can be implemented.
