Abstract: A system and method for extending the distance that xDSL services are able to be provided to subscribers. A DSLAM located at a Central Office is connected to a general-purpose network, such as the Internet. The DSLAM is additionally connected to a first fiber optic transceiver. The first fiber optic transceiver is connected via a fiber optic link to a second fiber optic transceiver located proximate to the subscribers' premises, preferably in a street cabinet. Each subscriber premise's equipment is connected to the broadband transceiver via subscriber lines. Electrical signals to be transmitted between the Central Office and the subscribers' premises are utilized to form a frequency division multiplexed signal. The frequency division multiplexed signal is used to modulate a light subcarrier for transmission across the fiber optic link. At the respective receiving transceiver, the frequency division multiplexed signal is reconverted to the electrical signals, which are then applied to the subscriber premises equipment or DSLAM, depending upon the direction of communication.

Abstract: A small form-factor transceiver module performs protocol translation, in addition to the conventional electrical and/or optical transmission media conversion. Such protocol conversion may enable transport of traffic from limited-range primary networks over long-range secondary networks, such as extension of Ethernet networks over low-rate TDM links. Additionally, such protocol conversion may enable interworking between different networks of differing technologies, such as transport of ATM traffic over Ethernet networks. The transceiver module may be a Small Form Factor transceiver (SFF), Small Form Factor pluggable module (SFP), Gigabit Interface Converter (GBIC) or any similar small form-factor module consisting of a housing, internal electronic circuitry and optionally optical components, and associated electrical or optical connectors. The transceiver module performs protocol translation by means of an integral protocol translation unit that performs standards-based or proprietary conversion between network protocols.
