Demonstration of injected locked Fabry-Perot laser diodes and reflected semiconductor optical amplifiers as colorless transmitters for WDM-PONs

In this paper, performance evaluation of different transmitters enabling colorless operation for WDM-PONs applications is carried out. Injected Locked Fabry Perot Laser Diode (IL-FPLD) and Reflective Semiconductor Optical Amplifier (RSOA) in external seeding and wavelength reuse scheme are modeled in VPITransmissionMaker® simulation platform. Upstream transmissions are performed at 1.25 Gb/s with distances up to 40 km, achieving a BER of ~ 1×10

, with an aggregate capacity of 40 Gb/s by using IL-FPLD. For the RSOA with external seeding, upstream transmission rates of 1.25 Gb/s and downstream transmission of 5 Gb/s are achieved in 43 km of fiber link achieving a BER of ~ 1×10
