Abstract:
1. An integrated multiple-rate optical time division multiplexing (OTDM) module comprising: at least one integrated controllable optical delay switching and combining array for introducing at least one prescribed optical delay between a first optical RZ signal stream and a reference optical RZ signal stream to facilitate time division multiplexing of the first and the reference optical RZ signal streams, wherein the at least one integrated controllable optical delay switching and combining array is adapted to controllably switch a path of the first optical RZ signal stream to one of a plurality of optical delay elements according to a data rate of the first optical RZ signal stream to introduce a selected one of a plurality of optical signal delays to the first optical RZ signal stream relative to the reference optical RZ signal stream, whereby the time division multiplexing of the optical RZ signal streams may be facilitated for a number of different data rates.
