Abstract: The present disclosure provides a multi-channel parallel optical transceiver module. The disclosed optical transceiver module/device may include a shell body and a circuit board located in the shell body, and an optical emitter base soldered to a first end of the circuit board. A notch located on the base, for engaging the first end of the circuit board, and the optical emitter base engaged with the first end of the circuit board may be soldered to two sides of the circuit board. The optical emitters may be disposed in parallel on the base, and separated from each other by a block. A lens and a laser may be disposed at a first side of each of the optical emitters that is adjacent to the circuit board, and an optical monitor may be disposed on a second end of the circuit board adjacent to the laser.
