1.25-Gb/s Transmission Over an Access Network Link With Tunable OADM and a Reflective SOA

The emerging broadband services and the avalanche-like growth of the broadband subscribers result in the intensification of data traffic in access networks. This drives the development of last-mile technologies to support multiservice provision on high bit-rate-capable reconfigurable networks. In this letter, we present the first transmission experiments carried out on the testbed of a hybrid wavelength-division-multiplexing/time- division-multiplexing access network based on cost-efficient elements like an integrated optical add-drop multiplexer and a reflective semiconductor optical amplifier. We successfully transmit two 1.25-Gb/s wavelength channels over 26-km standard single-mode fiber carrying data to and from the user.
