Optical-to-electrical conversion on rear-panel transition cards

摘要

A method and apparatus for improving fault tolerance of a midplane system is disclosed.In one embodiment, the method and apparatus provide a rear optical interface on a transition card of the midplane system. The method and apparatus then allow a main card of the midplane system to access a fiber optic cable coupled to the rear optical interface via an optic transceiver and a data format transceiver on the transition card.
