The diameter of the core of the optical fiber 2 to be measured is 8 μm or more and 10 μm or less, preferably 9 μm, and may be 50 μm or 62.5 μm.
The core of the receiving fiber 3 has a diameter of 50 μm or 62.5 μm.
The optical fiber connector of the polarity detection device further comprises a laser emitter and a laser detector, light emitted by the laser emitter enters the incident optical fiber, and the laser detector receives light emitted from the receiving optical fiber. The laser transmitter has a Transmitter Optical Subassembly (TOSA) and the laser detector has a Receiver Optical Subassembly (ROSA).
As shown in FIG. 1, in the first embodiment, the incident fiber is 9/125 μm, the measured fiber is 9/125 μm, and the receiving fiber is 62.5/125 μm, since the receiving fiber 62.5/125 μm is much larger than the incident fiber 9/125 μm, it is considered that there is no light loss, and there is a small error loss from the incident fiber 9/125 μm to the measured fiber 9/125 μm.
