Abstract
A multi-service, adaptable optical network unit (ONU) is disclosed for use in a fiber-to-the-curb (FTTC) digital loop carrier system, including a multi-service common card and a plurality of multi-media service cards that are connected to the common card using a card-link interface. The card-link interface is preferably a high-speed LVDS serial-bus connection that is organized in a star configuration such that each service card is connected to the multi-service common card using a separate point-to-point card-link. By eliminating the traditional backplane structure found in present ONU designs, the present invention provides a scalable, adaptable, future-proof FTTC system that can transport present-day multi-media services as well as yet-to-be-defined future high-bandwidth applications.
