ABSTRACT:
An optical transport switching system having an all-optical switch that can be selectively configured to provide cross-connection and add/drop multiplexing functions. Optical circuit cards are provided in a chassis/bay, and connected by an optical backplane. The circuit cards may include access line interface cards, optical access ingress cards, transport ingress cards, transport egress cards, and optical access egress cards. An optical switching fabric provides selective optical coupling between the cards. The all-optical switch can be used in an optical network that allows external/access networks to access the optical network, including access networks that use Gigabit Ethernet or SONET signaling. Wavelength conversion is provided for non-compliant wavelengths of the access networks. A local area network enables control and monitoring of the cards by a local node manager.
