Time-slot interchange is investigated using an optical buffer with a large variable delay based on an active-vertical-coupler crosspoint switch. The delay could range from 1 to 999 time slots in our scheme, and the length of the time slot is correspondingly flexible. The experiment could be performed at a data rate of 10 Gbit/s. The results show the power penalty is about 1.5 and 5.6 dB, respectively, when the packets pass through two buffers and through one buffer nine times.
