Description

Optical cable jumper wire

Technical Field

The utility model relates to an optical cable jumper.

Background

Optical fiber jumpers are also known as optical fiber connectors, which are devices that make removable (movable) connections between optical fibers, and which precisely mate the two end surfaces of the optical fibers to maximize the coupling of the optical energy output by the transmitting optical fiber into the receiving optical fiber and to minimize the impact on the system due to its intervening optical links, which is a fundamental requirement of optical fiber connectors. To some extent, fiber optic connectors affect the reliability and various properties of the optical transmission system.

The optical fiber connector can be divided into common single-mode and multi-mode connectors of silicon-based optical fibers according to different transmission media, and other optical fiber connectors using plastic or the like as the transmission media; the structure of the connector can be divided into: FC. SC, ST, LC, D4, DIN, MU, MT, etc. Among them, ST connectors are commonly used for wiring equipment ends such as fiber distribution frames, fiber optic modules, and the like; whereas SC and MT connectors are typically used at the network device end. FC, PC (including SPC or UPC) and APC are classified according to the fiber end face shape; there are also single core and multi-core (e.g., MT-RJ) divisions by fiber core number. The optical fiber connector has wide application and various varieties. In practice, we generally distinguish between fiber optic connector configurations.

The main purpose of the optical fiber connector is to realize the connection of optical fibers. Optical fiber connectors, which are widely used in optical fiber communication systems, are of a variety and different structures. However, the basic structure of various types of optical fiber connectors is consistent, that is, most optical fiber connectors generally adopt high-precision components (comprising three parts of two pins and a coupling tube) to realize the alignment connection of optical fibers.

The method is to penetrate and fix the optical fiber into the contact pin, and to polish the contact pin surface to realize alignment in the coupling tube. The outer component of the contact pin is made of metal or nonmetal materials. The butt ends of the pins must be ground and the other end typically employs a bend limiting member to support the optical fiber or fiber optic cable to relieve the stress. The coupling tube is typically made of two halves of a synthetic, fastened cylindrical member made of ceramic, or bronze, etc., and is often provided with a metal or plastic flange to facilitate the mounting and securing of the connector. In order to align the optical fiber as precisely as possible, the machining precision of the pins and the coupling tubes is required to be high.

The optical cable is connected in the optical fiber connector, and the traditional optical cable wraps the optical fiber through the rubber-covered wire, and the rubber-covered wire is easily damaged under the condition of repeated bending or long-time bending, so that the performance of the optical fiber for transmitting signals is affected.

The utility model comprises the following steps:

the utility model aims to solve the defects in the prior art and provides an optical cable jumper.

An optical cable jumper comprises a shell, wherein a tail sleeve, a stop ring, a compression ring, a spring, a tail handle, an optical cable, an inserting core and an inner bushing are arranged in the shell;

The device capable of transmitting the optical path according to the required channel is called a connector, and the reserved or expected target and the required device are realized and completed. The basic requirements of a fiber optic connector are: the two end faces of the optical fibers are closely butted to minimize the impact on the system due to its intervening optical links so that the optical energy of the output of the transmitting fiber is maximized into the receiving fiber. The optical fiber connector has influence on the reliability and various performances of the optical transmission system to a certain extent;

the utility model replaces the rubber-insulated wire outside the optical fiber with the woven protective sleeve, can be matched with a 400G optical module for use, and realizes the transmission rate of a 400G channel. Because the outer side of the transmission unit adopts braiding protection, the softness and the bending resistance of the optical cable can be improved.

In order to ensure the connection of the lock pin, the lock pin is made of ceramic.

In order to ensure that the tail sleeve can be bent and that the tail sleeve cannot be bent and damaged, the tail sleeve is made of rubber.
