A wide-band photonic packet injection control module for optical packet switching routers

The implementation of a novel photonic injection control module that mediates packet injection into optical packet switching (OPS) routers is reported. Responding to a busy signal received from the OPS router, the module buffers the multiple-wavelength optical packets on a fiber delay line until a slot becomes available. The functionality of the module and its interoperability with a data vortex OPS router are demonstrated. Error-free (bit-error rate <10/sup -12/) routing of 80-Gb/s payload (eight wavelength-division multiplexing /spl times/10 Gb/s) is confirmed.
