Claim Text:
1. An optical module, the optical module comprises an optical transceiver assembly and a control circuit, the optical transceiver assembly comprises a first optical emitter and a second optical emitter; the control circuit is configured to control the first optical emitter to generate an optical signal of a first waveband, and the first optical emitter is configured to emit the optical signal of the first waveband to a transmission optical fiber; or, the control circuit is configured to control the second optical emitter to generate an optical signal of a second waveband, and the second optical emitter is configured to emit the optical signal of the second waveband to the transmission optical fiber; wherein the optical transceiver assembly further comprises an optical network interface, an optical axis of the first optical emitter being collinear with that of the optical network interface, an optical axis of the second optical emitter being perpendicular to that of the first optical emitter, a first beam splitter inclined relative to the optical axis of the first optical emitter being provided between the first optical emitter and the optical network interface, the second optical emitter being positioned on one side of the first beam splitter; the first beam splitter transmits the first optical signal emitted by the first optical emitter and reflects the optical signal transmitted by the second optical emitter, the transmitted first optical signal and the reflected second optical signal being both radiated onto the optical network interface; wherein, in the optical network interface, an end face facing the first optical emitter and the optical axis of the first optical emitter form a preset angle, so that invalid optical signals from the first optical signal and the second optical signal are reflected by the end face and then kept away from the first optical emitter and the second optical emitter.
