In this blog, ETU-Link will introduce what the fiber optic adapter is. And common types of fiber optic adapters.

Fiber optic adapters, also called flanges, are components that connect fiber-to-fiber or fiber-to-device. They are widely used in telecommunication networks, cable television networks, subscriber loop systems, and optical fiber link connections in regional networks. There are many types of fiber optic adapters. According to the connector type, it can be divided into LC fiber optic adapter, FC fiber optic adapter, SC fiber optic adapter, etc.; according to the mode of use, it can be divided into simplex fiber optic adapter and duplex fiber optic adapter; according to different manufacturing materials, it can be divided into Bronze fiber optic connectors and ceramic fiber optic connectors. Next, ETU-LINK will introduce the following fiber optic adapters in detail

1. LC fiber optic adapter, the interface types are square duplex LC and square simplex LC, and there are single-mode and multi-mode. The connection method is plug-in type, which is easy to plug and unplug. It is installed on the fiber distribution frame for connection Pigtails and patch cord.

2. SC fiber optic adapter, the interface type is square SC, single-mode and multi-mode, the connection method adopts plug-in type, the plug-in operation is convenient, it is installed on the optical fiber distribution frame, and is used to connect pigtails and patch cord. It is characterized by high compressive strength, small insertion loss fluctuation, high installation density, superior performance of the ceramic sleeve, stability and reliability.

3. FC fiber optic adapter, the interface type is round FC, the exterior is reinforced with a metal sleeve, and the screw is fastened. It is divided into single-mode, multi-mode and 10G. The ceramic sleeve has superior performance and its stable and reliable.

The above are the three common types of optical fiber adapters. Although the optical fiber adapter is relatively small and belongs to the small part of the optical fiber cabling, it is still so important in the optical fiber cabling system.

The alignment sleeve is the most important part of the optical fiber adapter. The effect of using the optical fiber adapter made of ceramic for the alignment sleeve is much better than that of the optical fiber adapter that uses metal as the alignment sleeve. This is because the crystal structure of the ceramic is very hard. It will not deform over time like metal materials, so it can achieve quick alignment and high-precision fiber end-face connection.
