Abstract

22-channel detuning capacity of a 2.5Gbit/s directly modulated FPLD based ONU under side-mode injection-locking for DWDM-PON is demonstrated with SMSR >35dB, Q-factor 6.8-9.2, locking range of 24nm, power penalty of -0.7dB, and BER of 10^-10 at -17dBm. The demonstrated side-mode injection-locked FPLD is a potential candidate to achieve the cost effective and high capability 2.5Gbit/s DWDM-PON systems. The maximum usable ONU channels of the side-mode injection-locking FPLD are 22, corresponding to a wavelength locking range of 24 nm. Direct modulation of the upstream channels was successfully obtained and shows high quality eye diagram at ONU transmission.
