Fully dynamic and reconfigurable optical add/drop multiplexer on 0.8 nm channel spacing using AOTF and 32-wave tunable LD module

We developed and confirmed the feasibility of a dynamic optical add drop multiplexer (OADM) system using an acousto optical tunable filter (AOTF) and a wavelength tunable LD module. A 4-concatenation transmission of this system was performed successfully.
