It is well known that the design of multi-channel optical fiber slip ring is very different from the design of single-channel optical fiber slip ring in terms of structure and principle. Multi-channel optical fiber slip ring mainly refers to two-channel and more than two-channel optical fiber slip rings. It mainly transmits two-way and four-way fiber optic connectors. In the design, it should be noted that the diameter range of the fiber is very small, especially the single-mode fiber is only 9 nanometers.
Therefore, it is very challenging to maintain precision and accuracy during design, which is very challenging for the processing and structure of the product.
In general, multi-channel optical fiber slip rings can only be made into channels for multi-mode optical transmission. Single-channel optical fiber slip rings can be divided into single-mode and multi-mode. The multi-channel optical fiber slip ring can only be made into multi-mode, so how to ensure the insertion loss and data transmission rate of the multi-channel optical fiber slip ring. Two or more optical fibers need to be rotated 360 degrees during transmission, and the optical fiber has no loss. It is necessary to add a lens to perform optical path conversion and re-approval, amplify, locate, and store a series of steps in the optical fiber. The design of the structure is not too difficult. What is difficult is the effect of processing accuracy and processing temperature on the material.
Therefore, we must have a set of approval mechanism and approval equipment to fine-tune and approve the optical path to minimize insertion loss. A structure with the best data transmission rate. Multi-channel optical fiber is widely used. However, due to the complexity of the design and the difficulty of processing, the price is very expensive. Many industries and fields are due to budget. Multi-channel Fiber Optic Slip Rings cannot be used.
