英文摘要 | An apparatus and method are provided employing a single set of reduced-cost optics for (de)multiplexing optical signals whereby the resultant signals have a flat-top response with increased channel spacing. One aspect of the present invention uses an optical interleaver (310) to separate channels from an input multichannel (multiplexed) optical signal (302) with a select channel spacing into, for example, two input signals consisting of alternating channels at twice the select channel spacing. The separated signals are then directed to a multiple-input, such as dual-input, (parallel)(de)multiplexer device (320) which further spacially separates the channels for coupling with single channel transmission fibers (322¿1-n?, 324¿1-n?). The input fibers to the (de)multiplexer are preferably offset relative to each other to accommodate channel shift resulting from the interleaver. |
