Optical fiber adapter, also known as flange, is a component that connects optical fiber to optical fiber or optical fiber to equipment, and is widely used for optical fiber link connection in telecommunications networks, cable television networks, user loop systems, and regional networks. There are many types of optical fiber adapters, including LC optical fiber adapter, FC optical fiber adapter, SC optical fiber adapter, etc; It can be divided into simplex optical fiber adapter and duplex optical fiber adapter according to the use mode; It can be divided into bronze optical fiber connector and ceramic optical fiber connector according to different manufacturing materials. The following optical fiber adapters will be introduced in detail.
1. LC optical fiber adapter has square duplex LC and square simplex LC interfaces, and has separate single-mode and multi-mode interfaces. The connection mode is plug and pull, which is convenient for plug and pull operation. It is installed on the optical fiber distribution frame to connect pigtails and jumpers.
2. SC optical fiber adapter, with square SC interface type, is divided into single mode and multi-mode. The connection mode is plug and pull type, which is convenient for plug and pull operation. It is installed on the optical fiber distribution frame for connecting pigtails and jumpers. It is characterized by high compressive strength, small insertion loss fluctuation, high installation density, superior performance, stability and reliability of ceramic sleeve.
3. FC optical fiber adapter, the interface type is round FC, the external part is reinforced with metal sleeve, and the screw is fastened. It is divided into single mode, multi-mode and 10 gigabit. The ceramic sleeve has excellent performance, stability and reliability.
These are the three common types of optical fiber adapters. Although the optical fiber adapter is small and belongs to the small part of optical fiber cabling, it does not affect its important position in the optical fiber cabling system.
The alignment sleeve is the most important part of the optical fiber adapter. The use effect of the optical fiber adapter with ceramic alignment sleeve is much better than that of the optical fiber adapter with metal alignment sleeve. This is because the crystal structure of the ceramic is very hard, and it will not deform as the metal material over time. Therefore, it can achieve rapid alignment and high-precision optical fiber end connection.
