Abstract

We report an experimental study of mitigation of optical homodyne crosstalk by phase scrambling. This is obtained by frequency shifting the signal-crosstalk heating noise power out of the receiver bandwidth. An increased tolerance to crosstalk of 7 and 5 dB is measured in a 2.5-Gb/s link of result indicates the feasibility of optical networking in the LAN/MAN domain by tolerating the relatively high crosstalk levels of present optical switching technology. Our experiment is in good agreement with theoretical results.
