Fiber Optic Adapters
Fiber optic adapters, also known as flanges or fiber optic connectors, are primarily used to connect two fiber optic connectors in a fiber cabling system, and are often assembled on various adapter panels and chassis. Important fiber optic connection components. Conventional fiber optic adapters are available in flanged and non-flanged versions, where the fiber optic adapter without a flange can be directly attached to a panel or tray, and the fiber optic adapter with a flange needs to be screwed.
Fiber Optic Adapter Features
1. Low insertion loss, less than 0.2 db per connection through an adapter.
2. Good interchangeability and repeatability.
Fiber Optic Adapter Structure
Taking the common LC-LC duplex fiber adapter as an example, it is made of corrosion-resistant plastic, has good corrosion resistance and internal shading, and is made of stainless steel clips, full flanges, dust plugs, and high-precision ceramic sleeves. The composition of the tube and other components ensures that the two connectors can be accurately connected while minimizing the loss. It should be noted that the main function of the flange of the fiber optic adapter is to fix the adapter on the adapter panel. Therefore, a variety of fine, fixed flanges are fired at the FOCC
How Fiber Optic Adapters Work
The key to fiber optic connection is the precise alignment of the fiber core, so the traditional connection methods (such as welding) have certain defects. The difference is that there is an alignment sleeve inside each fiber adapter, which can ensure the accuracy of the connection and achieve high-performance connection between fiber jumpers.
Fiber Optic Adapter Interface Type
According to the diversity of fiber optic connectors, there are many types of interfaces for fiber optic adapters, as shown in the figure below. According to the same connector at both ends of the fiber adapter, its interface can be divided into six types: LC-LC, SC-SC, ST-ST, FC-FC, MPO-MPO, and E2000-E2000. According to the different connectors at both ends of the fiber adapter, its interface can be divided into six types: LC-SC, LC-ST, LC-FC, SC-FT, SC-FC, and FC-ST. These two ends have different connections. The adapter for the device is often referred to as a hybrid adapter. In addition, the use of fiber adapters for SC and FC interfaces is relatively more widely used in all interface types.
Application Scope of Fiber Optic Adapters
Fiber optic adapters are widely used in fiber optic communications systems, fiber-to-the-home (FTTP), video transmission, cable television networks, local area networks, optical domain networks, and test instrumentation.
