Optical input buffers for the HiPower photonic ATM switch-analysis and experiments

We describe an optical input buffer for the HiPower photonic ATM switch. This buffer can control the cell throughput in accordance with back pressure signals and incoming optical cells. We analyze the cell loss probability of the optical input buffer. Only a small buffer size of five is needed to obtain a cell loss probability of less than 10/sup -15/ with 1024 ports. Experimental 10 Gb/s operation using optical fiber delay lines with gate control circuits shows that the bit error rate of the buffer is less than 10/sup -12/.
