Switched optical interconnect.

摘要

An ATM switch has an ATM switch core (1) comprising an NxN optical cross-connect core (10) and a set of N port cards (2), each including a selector (22). Associated with each port card is a satellite (3). Wavelength shift keyed signals that are wavelength division multiplexed are employed for routing ATM cells between the satellites (3) via the core (1) by way of optical fibres (4 and 5). <IMAGE>
