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.
其他摘要	提供了一种装置和方法，其采用单组降低成本的光学器件（de）多路复用光学信号，由此所得到的信号具有平顶响应，并具有增加的信道间隔。本发明的一个方面是使用光学交织器（310）将信道与输入多信道（多路复用）光学信号（302）分离，其中选择信道间隔为例如两个输入信号，该信号由选择信道两倍的交替信道组成。间距。然后将分离的信号导向多输入，例如双输入（并行）（解）多路复用器装置（320），其进一步在空间上分离用于与单通道传输光纤（322？1-n'耦合的通道）。324¿1-N？）。（de）多路复用器的输入光纤优选地相对于彼此偏移，以适应由交织器产生的信道偏移。
