The present invention relates to an optical transceiver using FEC, an optical transceiving system comprising the same, and a remote optical wavelength control method and, specifically, to an optical transceiver using FEC, the optical transceiver comprising: a laser diode driver (LDD) for driving a laser diode (LD) for outputting light; a transmitter optical sub-assembly (TOSA) for transmitting an optical signal received from the LD driver; a receiver optical sub-assembly (ROSA) for receiving the optical signal from the transmitter optical sub-assembly; a micro controller unit (MCU) for controlling the transmitter optical sub-assembly and the receiver optical sub-assembly and analyzing the optical signal; and a forward error correction (FEC) which is controlled by the micro controller unit and generates the optical signal by including, in an overhead excess data frame, control or monitoring request information of a subscriber-side base station.

Optical transceiver using FEC, optical transceiving system comprising same, and remote optical wavelength control method

According to the present disclosure, a controlling unit arbitrarily determines a current set temperature of a temperature setting unit to cause a light generating unit connected to the temperature setting unit to generate an optical signal having a wavelength according to the current set temperature, thereby making it possible to effectively reduce a wavelength overlap phenomenon that may occur when a plurality of R-ONUs in a passive optical network simultaneously transmit the optical signals.
