Description
Summary:The operation of a network-embedded colorless self-tuning transmitter for WDM networks is experimentally demonstrated from 2.5- up to 10.7-Gb/s data rates. Colorless operation is achieved by self-seeding an ultra-fast reflective semiconductor optical amplifier (RSOA) with the feedback signal reflected at the WDM multiplexer filter. In particular, the transmitter exploits a 2-Faraday rotators configuration to ensure polarization insensitive operation and allowing for the exploitation of high gain RSOAs, which can be designed to operate on a single polarization. The impact on the transmission of the fiber chromatic dispersion at different bit-rates and with different channel bandwidths of the WDM multiplexer filter is experimentally investigated up to 10.7 Gb/s. The tolerance to positive and negative dispersive loads is also assessed.
