Many people are not familiar with the characteristics of fiber optic connectors. Here, I will explain the characteristics of fiber optic connectors to you.
Due to the indispensable optical components of fiber optic connectors in fiber optic communication systems, global optical device manufacturers have invested a lot of manpower and material resources in active and in-depth research, and have developed various fiber optic connectors, which are now widely used in various types of optical fiber communication systems.
1. The fundamental composition of fiber optic connectors. Currently, most fiber optic connectors are composed of three components: two cooperative plugs and one coupling tube. Install two plugs into the tail end of a fiber optic cable: the coupling tube serves as an alignment sleeve, and in addition, the coupling tube is often equipped with metal or non-metallic flanges to facilitate the fixation of the connector device.
2. Alignment method for fiber optic connectors: There are two alignment methods for fiber optic connectors, namely fine component alignment and automatic alignment. The high-precision component alignment method is a commonly used method. This method involves threading and fixing optical fibers into the supporting sleeve of the plug, polishing or polishing the docking port, and completing alignment in the sleeve coupling tube. The supporting sleeve of the plug is made of stainless steel, stainless steel embedded with glass or ceramics, ceramic sleeve, molded fiberglass plastic, and other materials, and the mating end of the plug is ground, The other end usually uses a tortuous constraint component to support the optical fiber or fiber flexible cable to release stress. The coupling alignment sleeve is usually made of two halves made of materials such as ceramic, glass fiber reinforced plastic, or metal, and is made of a fixed cylindrical component. To ensure the alignment of the optical fiber, this type of connector has a high demand for the machining accuracy of the connector, plug, and sleeve coupling components, It is necessary to use ultra-high precision casting or mechanical processing technology for manufacturing, and the intervention loss of this type of fiber optic connector is within the range of (0.18~3.0) db.
