Detailed Description
As shown in fig. 1, in the optical fiber connector of the polarity detection device provided in the embodiment of the present invention, the polarity detection device is an MPO polarity detection device or an MTP polarity detection device. The optical fiber joint of the polarity detection device comprises an incident optical fiber 1, a detected optical fiber 2 and a receiving optical fiber 3, wherein the detected optical fiber 2 is positioned between the incident optical fiber 1 and the receiving optical fiber 3, light passes through the detected optical fiber 2 from the incident optical fiber 1 and is received by the receiving optical fiber 3, the diameter of the core of the detected optical fiber 2 is larger than or equal to that of the core of the incident optical fiber 1, and the diameter of the core of the receiving optical fiber 3 is larger than or equal to that of the core of the detected optical fiber 2. The core of a typical single mode fiber has a diameter of 9 μm (9/125 μm), and the core of a typical multimode fiber has diameters of both 50 μm (50/125 μm) and 62.5 μm (62.5/125 μm). The diameter of the core of the tested optical fiber is larger than or equal to that of the core of the incident optical fiber, the diameter of the core of the receiving optical fiber is larger than or equal to that of the core of the tested optical fiber, and light is incident to the core of a large area from the core of a small area, so that light loss can be reduced.
The diameter of the core of the incident optical fiber 1 is 8 μm or more and 10 μm or less, and in this embodiment, the diameter of the core of the incident optical fiber is 9 μm.
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.
As shown in FIG. 2, in the second embodiment, the incident fiber is 9/125 μm, the measured fiber is 50/125 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 in the measured fiber 50/125 μm to the receiving fiber 62.5/125 μm.
As shown in FIG. 3, in the second embodiment, the incident fiber is 9/125 μm, the measured fiber is 62.5/125 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 smaller error loss from the measured fiber 62.5/125 μm to the receiving fiber 62.5/125 μm.
In conclusion of the three tested modes, the light losses are basically consistent, and a set of polarity detection equipment can be adopted to realize the detection of single-mode MPO/MTP fibers and multi-mode MPO/MTP fibers.
When the light outlet of a Transmitter Optical Subassembly (TOSA) adopts 9/125 μm (namely, the incident optical fiber is 9/125 μm), and the light inlet of a Receiver Optical Subassembly (ROSA) adopts 62.5/125 μm (namely, the receiving optical fiber is 62.5/125 μm), when a single-mode MPO/MTP optical fiber is accessed, the connection of the optical fibers is 9/125 μm + 9/125 μm + 62.5/125 μm; when the multimode MPO/MTP optical fiber is accessed, the connection of the optical fiber is 9/125 mu m +50/125 mu m or 62.5/125 mu m + 62.5/125 mu m, and the light is incident from the core with small area to the core with large area, so that the adaptation loss can be reduced. As for qualitative test instruments such as a polarity detector and the like, the specific loss of an optical path does not need to be quantitatively analyzed, and after the optical path is designed, the optical fiber connector of the polarity detection equipment can detect the conventional products (9/125 mu m, 50/125 mu m, 62.5/125 mu m), thereby realizing the universality of the equipment and reducing the purchase and maintenance cost of the instrument.
