Abstract:
1. An optical subscriber network system comprising: a server bi-directional optical transmitter including: a subscriber bi-directional optical receiver including: wherein the optical transmitter and optical receiver are configured for transceiving image signals and Ethernet communication signals in two directions by a single laser diode and photo diode; and wherein the multiplexer and demultiplexer comprise time division multiplexer (TDM) and demultiplexer (TDDM), respectively; an Ethernet switch configured to (1) switch communication data transmitted from a demultiplexer to a subscriber computer, and (2) receive the communication data transmitted from the subscriber computer; a third PHY device for converting the MII signal into a multi level transmit-3 (MLT-3) signal wherein, the TX signal output from the second PHY device is used to operate the first PHY device.
