Optical fiber rapid cold connective device

Abstract

The invention relates to an optical fiber rapid cold connective device which comprises a hollow pipe (1) and a pressed block (4), wherein the hollow pipe (1) is a nominal aperture hollow-core pipe; the middle part of the hollow pipe (1) is provided with an opening so as to form a C-shaped groove (2); both ends of the central hole of the hollow pipe are provided with a conical guiding opening (3); and when the device is used, the pressed block (4) is arranged in the C-shaped groove (2). The bonding point of the optical fiber to be connected is arranged in the middle part of the C-shaped groove (2) of the hollow pipe. The connective method is characterized by simple structure, low cost and simple and rapid operation. The optical fiber rapid cold connective device is suitable for connecting the optical fibers in various environments, increases the matching degree of the optical fibers to be connected, effectively reduces the insertion loss of an adapter connector and increases the return loss.

Description

technical field [0001] The invention relates to a fast cold splicing device for optical fibers, which can simply and quickly realize the alignment and connection of optical fibers in engineering sites with harsh environments such as the field, and belongs to the technical field of optical fiber communication device manufacturing. Background technique [0002] In the process of optical network construction and optical cable laying, the connection of optical fibers relies on thermal fusion technology, that is, using a fusion splicer. However, in many construction sites in the wild, in harsh environments and without power supply, thermal welding technology is difficult to play a role. Therefore, there is an urgent need for a fast and effective optical fiber cold splicing method to realize optical fiber connection under difficult conditions. Most of the existing cold splicing methods adopt the "V" groove design, but the processing of the "V" groove requires high precision and c...

AI Technical Summary

Problems solved by technology

The existing cold splicing methods mostly use the "V" groove design, but the processing of the "V" groove requires high precision and complicated packaging, which increases the production cost accordingly

Another method of docking using a curved capillary will generate an angle between the end faces of the two optical fibers to be connected, which will introduce additional loss, and it is not convenient to add matching liquid and stabilize
