40Gbit/s-class-λ-tunable WDM/TDM-PON using λ-selectable B-Tx and 4 x M cyclic AWG router for flexible photonic aggregation networks

This paper proposes a 40Gbit/s-class-λ-tunable WDM/TDM-PON for flexible photonic aggregation networks that achieves the aggregation of a large number of users using the DWBA algorithm without an L2-SW. It also clarifies the scalability of the proposed system in terms of the transmission distance and the number of users. A λ-switching transmission experiment was conducted using a newly developed 10Gbit/s x 4λ selectable B-Tx and 4 x 4 cyclic AWG router.
