Optical transceiver for use in low bitrate communication systems

The present document relates to an optical transceiver (100) comprising: - a transmitter element (110) adapted to emit a first optical signal (OS1) using a p-n-junction; - an optical output (120) for transmitting the first optical signal (OS1) emitted by the transmitter element (110) to an optical communication link (130) in a forward direction (FWD); wherein the transmitter element (110) is adapted to - receive a second optical signal (OS2) propagating in the optical communication link (130) in a backward direction (BWD) using the same p-n-junction; and - generate an electrical signal based on the received second optical signal (OS2).
