Device for frequency band demultiplexing |
摘要 |
The invention relates to an optical demultiplexing system for separating frequency bands of a frequency-division multiplex, said system comprising a 1 to n first cyclic demultiplexer for demultiplexing said multiplex into n interleaved frequency combs each comprising m channels and a second cyclic demultiplexer for separating the channels of said n interleaved combs to obtain m consecutive bands comprising n consecutive frequencies, characterized in that said second multiplexer is an m to m cyclic demultiplexer having n input ports connected to respective output ports of said 1 to n first cyclic demultiplexer and in that the numbers n and m are mutually prime numbers.
