100 Gbit/s synchronous all-optical time-division multiplexing multi-access network testbed

We have demonstrated a slotted OTDM multi-access network testbed capable of operating at 112.5 Gbit/s line rates. A headend generates a 12.5 Gbit/s global clock and defines the 100 ns system slot boundaries. The transmitter generates a 4-bit address header and 100 Gbit/s pseudo-random data payload using pulse-position modulation signaling format. The receiver achieves self-synchronization to slot timing, 4-bit address comparison, and data rate downconversion using three cascaded all-optical logic gates operating at the 112.5 Gbit/s network line rate.
