Abstract

Optical path layer technologies are expected to be crucial in creating a flexible network architecture and expanding network capacity in broadband ISDN (B-ISDN) [1]. The optical cross-connect (OXC) is the main component in an optical transport network. OXC systems must offer a compact, economical switch architecture that allows effective modular growth. The OXC systems must also have robust network failure recovery, because large-capacity optical networks require a highly reliable optical path layer.
