1. An optical module, comprising:
a housing;
a main board;
first and second optical circulators; and
first and second optical fiber adapters;
wherein the housing is surrounded by a receiving cavity, and a first end of the housing is provided with first and second connecting cavities, the first optical fiber adapter being arranged at the first connecting cavity, the second optical fiber adapter being arranged at the second connecting cavity, the main board being at least partially arranged in the receiving cavity
and being provided with first and second transmitting units and first and second receiving units, an output end of the first transmitting unit being connected to a first port of the first optical circulator, an input end of the first receiving unit being connected to a third port of the first optical circulator, and a second port of the first optical circulator being connected to the first optical fiber adapter, an output end of the second transmitting unit being connected to a first port of the second optical circulator, an input end of the second receiving unit being connected to a third port of the second optical circulator, and a second port of the second optical circulator being connected to the second optical fiber adapter;
wherein an optical signal output by the output end of the first transmitting unit is transmitted along the first port of the first optical circulator to the second port of the first optical circulator;
wherein the first optical fiber adapter receives an optical signal input from outside, and transmits the optical signal received from outside to the third port of the first optical circulator along the second port of the first optical circulator;
wherein an optical signal output by the output end of the second transmitting unit is transmitted along the first port of the second optical circulator to the second port of the second optical circulator; and
wherein the second optical fiber adapter receives an optical signal input from outside, and transmits the optical signal received from outside by the second optical fiber adapter to the third port of the second optical circulator along the second port of the second optical circulator.
