ABSTRACT:
An optical transceiver for transmitting light source control information, which is applied to a Subcarrier Multiplexing optical network, is disclosed. The optical transceiver includes a controller, an SCM frame generation/restoring unit, a modulator/demodulator, and an EO/OE converter. The controller controls transmission of light source control information or collects received light source control information. The SCM frame generation/restoring unit generates an SCM frame containing light source control information received from the controller. The modulator/demodulator modulates an SCM frame generated by the SCM frame generation/restoring unit into a signal suitable for transmission. The EO/OE converter converts a transmission signal modulated by the modulator/demodulator into an optical signal and transmits the optical signal through an optical fiber. An optical network having a telephone office OLT and subscriber ONTs, each having the optical transceiver, is also disclosed.
