An optical module includes a light receiving assembly and a first fiber optic adapter. The light receiving assembly includes a first lens group, a plurality of wavelength division demultiplexers and at least one light receiving component. The first lens group is configured to split optical signals transmitted to the first cavity body for a first time according to a wavelength to obtain a first optical signal beam and a second optical signal beam. The plurality of wavelength division demultiplexers include a first wavelength division demultiplexer and a second wavelength division demultiplexer. The first wavelength division demultiplexer is configured to split the first optical signal beam for a second time according to a wavelength. The second wavelength division demultiplexer is configured to split the second optical signal beam for a second time according to a wavelength. The light receiving component includes a plurality of light receiving chips.

Optical module

An optical module includes a light emitting assembly. The light emitting assembly includes a plurality of lasers, a plurality of wavelength division multiplexers and a lens group. The plurality of lasers emit a plurality of optical signals. The plurality of wavelength division multiplexers multiplex the plurality of optical signals into a plurality of composite optical signals. The lens group includes a first lens, a second lens, and a third lens. The second lens is configured to transmit a first part of the plurality of composite optical signals exited from the first lens, reflect a second part of the plurality of composite optical signals exited from the third lens to the first lens, and transmit the second part of the plurality of composite optical signals reflected by the first lens, so as to multiplex the plurality of composite optical signals into the merge composite optical signal.

The present disclosure discloses an optical module including a circuit board; a housing assembly including a light-receiving portion and a light-emitting cavity separated via a separation board and stacked one above the other, one side of the housing assembly adjacent to the circuit board being provided with a first notch through which one end of the circuit board is inserted into the housing assembly; a light-receiving assembly disposed in the light-receiving portion and electrically connected to an upper surface of the circuit board; and a light-emitting assembly disposed in the light-emitting cavity and electrically connected to a lower surface of the circuit board; a concave region is formed in the light-emitting cavity, and a laser assembly of the light-emitting assembly is arranged therein to lift the laser assembly to reduce height difference between wire bonding surface of the laser assembly and lower surface of the circuit board.

The present disclosure discloses an optical module including: a circuit board; a housing assembly divided by a separation board into a first portion and a second portion that are stacked one above the other, wherein a light-emitting cavity is formed in the second portion, and a partition wall is provided in the first portion to separate the first portion into a light-receiving cavity and a slot, and is provided with a plurality of light-passing holes via which the light-receiving cavity is in communication with the slot; an optical fiber adapter disposed in the housing assembly and in communication with the light-receiving cavity; a light-emitting assembly arranged in the light emitting cavity and electrically connected to the circuit board, wherein heat generated by the light-emitting assembly is conducted to a surface of the housing assembly via the partition wall; and a light-receiving assembly.
