1. An optical module, comprising:
a shell;
a circuit board disposed in the shell;
at least one of a light-transmitting chip or a light-receiving chip that is disposed on the circuit board, the light-transmitting chip being configured to generate an optical signal, and the light-receiving chip being configured to receive an optical signal from an outside of the optical module;
a lens assembly disposed on the circuit board, covering the at least one of the light-transmitting chip or the light-receiving chip, and configured to change a propagation direction of an optical signal incident to the lens assembly;
an optical fiber ferrule assembly connected to the lens assembly, and configured to transmit an optical signal transmitted into the optical fiber ferrule assembly; and
a fixing plate configured to fix the optical fiber ferrule assembly to the lens assembly; wherein
the fixing plate includes:
a main body portion abutting against an end face of the optical fiber ferrule assembly away from the lens assembly;
a first side plate connected to an end of the main body portion;
a second side plate connected to the first side plate, and abutting against the shell;
a third side plate connected to another end of the main body portion;
a fourth side plate connected to the third side plate, and abutting against the shell; and
a through hole disposed on the main body portion, and the optical fiber ferrule assembly passing through the through hole; wherein
the first side plate and the main body portion have a first included angle therebetween, and the second side plate and the first side plate have a second included angle therebetween;
the third side plate and the main body portion have a third included angle therebetween, and the fourth side plate and the third side plate have a fourth included angle therebetween; and
the first included angle, the second included angle, the third included angle, and the fourth included angle are all obtuse angles.
