Patent ID: 7421206

Claim:
An optical transceiver for transmitting light source control information, the optical transceiver being applied to a telephone office OLT and a subscriber ONT in an optical network, the transceiver comprising: a controller for controlling transmission of light source control information used for Optical Beat Interference (OBI) control, and collecting received light source control information to perform light source control; an SCM frame generation/restoring unit for generating an SCM frame containing light source control information received from the controller, and restoring a received SCM frame to original data by extracting light source control information from the received SCM frame and transferring the extracted information to the controller; a modulator/demodulator for modulating an SCM frame generated by the SCM frame generation/restoring unit into a signal suitable for transmission, and demodulating a received signal into an SCM frame and transferring the SCM frame to the SCM frame generation/restoring unit; and an EO/OE converter for converting a transmission signal modulated by the modulator/demodulator into an optical signal and transmitting the optical signal through an optical fiber, and converting an optical signal received through the optical fiber into an electrical signal and transferring the electrical signal to the modulator/demodulator.
