Abstract

A 12-channel wavelength division multiplexed (WDM) passive optical network (PON) at 155 Mb/s with 63 km of standard single-mode fiber (SMF) was demonstrated under simulated outside plant temperature conditions. A multifrequency laser (MFL) was used as the transmitter and a waveguide grating router (WGR) as the demultiplexer. A 20/spl deg/C/h temperature change of the WGR could be tracked by changing the MFL temperature and resulted in a power penalty in the detected bit-error rate (BER) of less than 0.75 dB. A scheme to increase the tracking sensitivity by multiple WGR passes is demonstrated.
