A.8 Isolation
1.
2.
It is a parameter of the demultiplexer and indicates the separation of the
multiplex optical channel signals from the demultiplexer.
The higher the channel isolation is, the better the frequency selection
performance of the WDM equipment. Consequently, the crosstalk suppression
ratio becomes higher and the mutual interference between multiplex optical
channels becomes lower.
Channel isolation includes adjacent channel isolation and non-adjacent channel
isolation.
Adjacent channel isolation
It is the ratio between the output optical power of an optical channel and the leak
optical power on this channel from an adjacent optical channel signals that has
the same output power.
It indicates the isolation of the demultiplexer from the two adjacent multiplex
optical channel signals.
Non-adjacent channel isolation
It is the ratio between the output optical power of an optical channel and the leak
optical power on this channel from a non-adjacent optical channel.
It indicates the isolation of the demultiplexer from the non-adjacent multiplex
optical channel signals.
