Claim:
1. A method of routing signals from a set of input links, each input link carrying multiple spectral bands, to a set of output links, the method comprising: arranging a plurality of temporal rotators into temporal-rotator groups; directing each spectral band of said each input link to a respective temporal rotator in each temporal-rotator group; and for each temporal-rotator group, combining output spectral bands of different temporal rotators onto a respective subset of output links of said set of output links so that each output link comprises an output spectral band from each temporal rotator of said each temporal-rotator group; connecting each timing circuit of a plurality of timing circuits to an output of a respective first temporal rotator and to an input of a respective second temporal rotator of said plurality of temporal rotators; and configuring said each timing circuit to:
