Optical movable connector, commonly known as flexible joint, generally called optical connector, is a reusable passive device used to connect two optical fibers or cables to form a continuous optical path. It has been widely used in optical fiber transmission lines and optical fiber distribution frames. Among optical fiber testing instruments and meters, it is the most used optical passive device.It has the characteristics of moisture resistance, low temperature resistance, dry heat resistance, welding heat, etc.
The article contains following:
1,The feature of moisture proof
2,It is low temperature resistance materials
3,The rast connector is anti-corrosion
1,The feature of moisture proof
The rast connector has a special moisture-proof function. The rast connector can be used in a low temperature environment, which is not possible with many connectors.
To a certain extent, fiber optic connectors also affect the reliability and performance of the optical transmission system. When installing any optical fiber system, it is necessary to consider connecting optical fibers or cables with each other in a low-loss method to realize the connection of optical links. The connection of the optical fiber link can be divided into two types: permanent and active. The permanent connection is mostly realized by welding, bonding or fixed connectors; the movable connection is generally realized by movable connectors.
Sometimes you need to consider the difficulty and stability of connecting optical fibers, especially in the field. Sensitivity to environmental factors, such as changes in cleanliness and vibration, requires a device that depends on the type of connector.
2,It is low temperature resistance materials
The rast connector is a small, high-waterproof SC single-core waterproof connector. The built-in SC connector inner core reduces the size of the waterproof connector better. The shell is made of special plastics that are resistant to high and low temperature, acid and alkali corrosion, and ultraviolet rays. The auxiliary waterproof rubber gasket is sealed and waterproof. Its waterproof performance can reach IP67 level. Unique spiral bayonet design, suitable for 3.0-5.0mm single-core circular optical cable or FTTH sheathed fiber home optical cable.
In this method, the optical fiber is inserted and fixed in the pin, and the surface of the pin is polished to achieve alignment in the coupling tube. The outer components of the pins are made of metal or non-metal materials. The butt end of the pin must be polished, and the other end usually uses a bending restriction member to support the optical fiber or optical fiber cable to relieve stress. Coupling tubes are generally made of two-half synthetic, fastened cylindrical members made of ceramic, bronze or other materials, and are often equipped with metal or plastic flanges to facilitate the installation and fixation of the connector. In order to align the optical fiber as accurately as possible, the processing accuracy of the pin and coupling tube is very high.
3,The rast connector is anti-corrosion
The optical fiber cable is potted with silica gel in the optical fiber connector, which prevents the optical fiber cable from being damaged by external thermal stress and chemical stress, and ensures that the product can work normally under low temperature, damp heat, and mold environment.
The optical fiber connector of the utility model adopts a sealing design. The shell, the shell cover, the potting silica gel, the dustproof cover, the waterproof gasket, and the sealing gasket are connected as a whole to seal the optical fiber cable in it. All connectors are made of metal The material, coupled with the function of the elastic sealing gasket, makes it have good waterproof and anti-corrosion performance.
