OPTICAL COMMUNICATIONS SYSTEMS, DEVICES, AND METHODS

摘要

A method of receiving optical channels including providing an optical band filter (81) configured to filter at least one optical channel from a multiple channel optical signal and provide a band filtered optical signal. A periodic filter (83) is configured to filter and/or shape one channel from the band filtered optical signal and provide the periodic filtered, shaped signal to a receiver and other optical system. The invention also relates to corresponding systems and apparatuses.
