Single mode double layer parallel optical fiber array

Abstract

The invention belongs to the technical field of optical fibers, and particularly relates to a single mode double layer parallel optical fiber array. The array comprises a first array substrate, a second array substrate, a cover plate, a silicone cushion layer, a protective cover sheet, splints, a small hinge, an optical fiber branch line, an MT joint, a V-shaped groove, a positioning right angle groove, a rubber connecting column, a connecting block, a positioning right angle inserting board, an adhesive layer, a silicone pressing piece and a glue positioning strip. The array achieves the fixing effect of the optical fibers to prevent the falling off of the optical fibers by arranging the splints on the surface edges of the first array substrate and the second array substrate and bonding the silicone cushion layer and clamping fiber branches in the optical fiber array by rotating the splints, and the exposed fiber branches of the surfaces of the first array substrate and the second array substrate are protected by the protective cover sheet and the silicone cushion layer to prevent the fiber branches from being affected by external factors.

Description

Technical field [0001] The invention belongs to the technical field of optical fibers, and specifically is a single-mode double-layer parallel optical fiber array. Background technique [0002] The optical fiber array uses a V-shaped groove to install an optical fiber, a bundle of optical fibers or an optical fiber ribbon on the array substrate. The optical fiber array is the part of the bare optical fiber with the fiber coating removed is placed in the V-shaped groove and is held by the presser component. Pressurized and bonded by an adhesive, at the front end, the optical fiber is precisely positioned to connect to the PLC, and the joints of different optical fibers are installed on the array substrate. [0003] The existing single-mode double-layer optical fiber array has a relatively simple structure. When the optical fiber is connected, part of the bare optical fiber is exposed to the outside, which is easily affected by external factors. When the optical fiber array is instal...

AI Technical Summary

Problems solved by technology

[0003] Due to the relatively simple structure of the existing single-mode double-layer optical fiber array, when connecting the optical fibers, some exposed optical fibers are exposed to the outside, which is easily affected by external factors, and when the optical fiber array is installed, due to the covering plate The connection with the array substrate is easily skewed, and it is easy to affect the cable fixing
