Abstract

ATM cells are switched in optical domain by prototyping a WDM ATM multicast switch. By taking advantage of both optical and electronic technologies, two planes, optical switching plane and electronic control plane, are constructed. ATM cells are routed through the optical switching plane, while their headers are extracted and processed in the electronic plane that controls the optical devices and routes the cells to proper output ports. The subsystem can adjust the phases of optical cells at 2.5 Gbit/s to a reference cell clock with the adjustment range of 1 to 511 bits and with a precision of 1/4 bit. A sampling method is used to achieve the 100 ps precision without using a 10 GHz clock.
