Abstract: A coupling interference method was proposed to research the problem of interference occurring with optical cross-connects in the transparent optical network. To quantify the signal quality of the communication system, the operational model was simulated and the influences of interfering source on the legal signal with different traffic rates, interfering power ratio were analyzed based on this method. Multiple verification experiments were established and the experimental results shows that this method are helpful for testing the existence of interfering source and preventing the influence of interfering source on legal signal in the transparent optical network.

Key words: coupling interference, transparent optical network, optical cross-connect, traffic rate, bit error rate
