    • An optical analyzer (14) for performing spectral analysis on an optical beam (18) includes an optical filter (28), a mover (30), an optical launcher (36), and an optical receiver (38). The optical filter (28) includes a filter area (46) that is a narrow band pass type filter having multiple alternative center bandwidths that are distributed along the filter area (46). The mover (30) moves the optical filter (28). The first optical launcher (36) directs the optical beam (18) at the filter area (46) so that the optical beam (18) is near normal incidence to the filter area (46). The optical analyzer (14) can be used to simultaneously monitor multiple optical signals. Additionally, the optical analyzer (14) can include a beam redirector (40) that causes the optical beam (18) to make two passes through the optical filter (28).

    • To support interleaving of optical channels and to provide sufficient isolation between such interleaved channels, a circulator (60-62) receives, on an optical fiber (16-18), a broadband signal containing a plurality of adjacent channels. The circulator selectively routes the broadband signal through a filter (64, 66) to isolate, on an individual basis, at least one desired channel. A filtered signal, corresponding to the at least one desired channel, is then output from the filter (64-66) and reflected back into the filter by a mirror (68-70) such that the at least one desired channel is subjected to a second filtering process that further improves isolation of the at least one desired channel. Following this second filtering process, the at least one desired channel is applied to the circulator (60-62) for re-inserting into the optical fiber (16-18), as illustrated in FIG. 6. To mitigate the effects of four-wave mixing in each bidirectional optical fiber, a channel assignment plan ensures that pairs of adjacent channels are assigned on a mutually exclusive basis to at least one of an up-link and a down-link direction.
    • 为了支持光信道的交织并且在这种交织信道之间提供足够的隔离,循环器(60-62)在光纤(16-18)上接收包含多个相邻信道的宽带信号。 循环器选择性地将宽带信号路由通过滤波器(64,66),以在个别的基础上隔离至少一个期望的信道。 然后从滤光器(64-66)输出对应于至少一个期望通道的滤波信号,并通过反射镜(68-70)反射回滤光器,使得至少一个期望的通道经受 第二滤波处理,其进一步改善所述至少一个期望信道的隔离。 在该第二滤波处理之后,将至少一个期望信道施加到循环器(60-62)以重新插入到光纤(16-18)中,如图6所示。 为了减轻每个双向光纤中四波混频的影响,信道分配方案确保相邻信道的对在互斥的基础上被分配给上行链路和下行链路方向中的至少一个。
