Description

Multi-core fiber optic terminal fixture

The invention provides a multi-core optical fiber terminal fixture, and in particular, a multi-core optical fiber terminal fixture whose fixture body has a plurality of fixture through holes and a plurality of fixture guide holes.

Fiber optic cable is a widely used optical communication cable for high-speed signal transmission. Generally speaking, fiber optic cable includes optical fiber and coating, where the optical fiber is coated inside the coating. The optical signal input from one end of the optical fiber can be transmitted to the other end through the optical fiber. Compared with cable transmission, it has a very small loss rate during the entire transmission process. Therefore, it is often used as a long-distance signal transmission medium.

When connecting different optical fibers, a head cover (ferrule) with multiple through holes is usually used to hold the optical fibers so that part of the optical fibers are exposed from the head cover. However, in the process of fixing the optical fiber cable to the head cover, it is easy to produce defective products due to the deviation and bending of the optical fiber.

The inventor of the present invention has devoted all his efforts to research and develop a multi-core optical fiber terminal fixture that can avoid the phenomenon of defective products due to the deviation and bending of the optical fiber when the optical fiber cable is fixed to the headgear.

This invention provides a multi-core optical fiber terminal fixture for assisting in fixing an optical fiber cable having a plurality of optical fibers to a multi-core optical fiber headgear having a plurality of headgear through holes and a plurality of headgear guide holes, comprising: A fixture body having a plurality of fixture through holes and a plurality of fixture guide holes, wherein the number and positions of the plurality of fixture through holes correspond to the plurality of optical fibers and the plurality of headgear through holes, and the number and positions of the plurality of fixture guide holes correspond to the plurality of headgear guide holes.

In one embodiment, in the multi-fiber terminal fixture, the plurality of fixture through holes are arranged in more than one row.

In one embodiment, in the multi-fiber optical terminal fixture, the plurality of fixture through holes are arranged in an array of 12×1 or more.

In one embodiment, in the above-mentioned multi-fiber optical terminal fixture, the fixture body of the multi-fiber optical terminal fixture is composed of a plurality of body components, wherein each row of the plurality of fixture through holes is respectively composed of two of the plurality of body components.

In one embodiment, the multi-core optical fiber terminal fixture further includes: A plurality of guide members, which are inserted through the plurality of fixture guide holes.

Thus, the multi-core optical fiber terminal fixture of the invention can effectively avoid the phenomenon of defective products caused by the deviation and bending of the optical fiber during the process of fixing the optical fiber cable to the multi-core optical fiber head cover.
