Experimental evaluation of optical crosstalk mitigation using phase scrambling

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.
