Disclosed are an optical module, an optical communication device and an optical transmission system. The optical module includes a housing; a main board where are arrange a first transmitting unit and a first receiving unit; a first optical circulator, a first port of which is connected to an output end of the first transmitting unit, and a third port of which is connected to an input end of the first receiving unit; and a first optical fiber adapter connected to a second port of the first optical circulator, wherein an optical signal from the output end of the first transmitting unit is transmitted to the second port along the first port of the first optical circulator; and the first optical fiber adapter receives an optical signal input from outside, and transmits it to the third port along the second port of the first optical circulator.

Optical module

An optical-path-displacement-compensation-based emission optical power stabilization assembly, comprising: a laser, a lens, and an optical fiber coupling port disposed on a first substrate and a second substrate according to a preset arrangement scheme, wherein an expansion coefficient of the second substrate is larger than that of the first substrate, and the preset arrangement scheme enables initial distances between the laser and the lens, between the lens and the optical fiber coupling port, and/or between the laser and the optical fiber coupling port to differ from respective optical coupling distances from an optical coupling point by a preset value, thereby ensuring that a coupling loss on an optical path changes along with the temperature, forming a complementary effect with respect to an optical power-temperature curve of the laser, which reduces a temperature-caused fluctuation of the emission optical power of an optical assembly.
