Abstract:
1. A single-fiber subassembly, comprising: a first photodiode for receiving incident light and a laser diode for transmitting emergent light; a same-wavelength optical splitter having a positive direction and comprising a first birefringent plate, a half-wave plate, a 45° Faraday rotator, and a second birefringent plate that is the same as the first birefringent plate, which are arranged in sequence along the positive direction and oriented perpendicular to the positive direction; a reflector arranged on an incident light path between the first photodiode and the same-wavelength optical splitter; a first receiving transistor outline configured to package the first photodiode; and a transmitting transistor outline configured to package the laser diode, wherein:
