Abstract
A single-fiber bidirectional optical assembly includes an optical emitter, an optical receiver, a lens assembly, a first filter, a second filter, an optical power attenuator, and an optical fiber interface end. The optical fiber interface end is used for being connected to an optical fiber, a downlink optical signal emitted by the optical emitter is focused by the lens assembly and is then emitted to the optical fiber sequentially through the first filter and the optical fiber interface end and is transmitted by the optical fiber, and an uplink optical signal transmitted by the optical fiber passes through the second filter and is then received by the optical receiver. The optical power attenuator is arranged between the optical emitter and the optical fiber interface end, and the transmittance of the optical power attenuator varies with the wavelength of the optical signal.
