MULTI-FILTER CAVITY OPTICAL CHANNEL MONITORING SYSTEM
摘要
A channel monitoring system has improved the spectral filtering accuracy by using a tunable filter system that transmits the optical signal through serial filter cavities. This has the effect of dramatically narrowing the filter's transfer function. Moreover, it improves side mode rejection. In the preferred embodiment, the filter is implemented in a double-pass configuration.
