A single-mode double-layer optical fiber array

Abstract

The invention belongs to the field of optical fiber technology, specifically a single-mode double-layer parallel optical fiber array, including an array substrate one, an array substrate two, a cover plate, a silica gel pad, a protective cover sheet, a splint, a small hinge, an optical fiber branch line, MT joints, V-shaped grooves, positioning right-angle grooves, rubber connecting columns, connecting blocks, positioning right-angle inserts, adhesive layers, silicone pressure sheets and glue positioning strips. In the present invention, a splint is arranged on the surface edge of the array substrate 1 and the array substrate 2, and the silica gel pad is bonded and connected, and the optical fiber branch connected to the optical fiber array is clamped and connected by the rotating splint, so as to realize the fixing effect on the optical fiber and avoid the loss of the optical fiber, and The exposed optical fiber branches on the first surface of the array substrate and the second surface of the array substrate are protected by the protective cover sheet and the silica gel pad to prevent the optical fiber branches from being affected by external factors.

Description

technical field [0001] The invention belongs to the field of optical fiber technology, in particular to a single-mode double-layer optical fiber array. Background technique [0002] The optical fiber array is to install an optical fiber, a bundle of optical fibers or an optical fiber ribbon on the array substrate by using a V-shaped groove. Pressurized and bonded by adhesive, at the front end, the fiber is precisely positioned for connection to the PLC, and the splices of different fibers are mounted on the array substrate. [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 to the array substrate tends to be skewed, which tends to affect cable fixing. In view of this, the present invention pro...
