The fiber optic adapter is also called a flange or fiber optic connector. Its main function is to connect two fiber optic connectors in the fiber optic wiring system. It is usually assembled on various adapter panels and chassis. Important optical fiber connection components, widely used in CATV, LANs, Video transmission,Telecommunication network and FTTH fiber to the home.
Conventional fiber optic adapters are divided into two types: with flange and without flange. The fiber adapter without flange can be directly stuck on the panel or tray, while the fiber adapter with flange needs to be fixed with screws.
The connector type at both ends of the fiber optic adapter is the basic attribute of the fiber adapter. According to connectors at both ends of the fiber adapter are the same or different, fiber optic adapter types include as follows:

Connectors are the same at each end:
• LC-LC
• SC-SC
• ST-ST
• FC-FC
• MPO-MPO
Connectors are different at each end:
• LC-SC
• LC-ST
• LC-FC
• SC-ST
• SC-FC
• FC-STFurther, based on different fiber transmission modes and fiber cores inserted, optic adapters can be divided into simplex/duplex fiber optic adapters and single-mode/multimode fiber optic adapters.
What is the structure of the fiber optic adapter?
Take the common LC-LC duplex fiber optic 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 pipe and other components can ensure that the two connectors are accurately connected while reducing the loss as much as possible.
Features of Fiber Optic Adapters
Optical fiber is connected by the adapter through its inner opening sleeve to ensure the maximum connection between the optical connectors. Optical fiber adapters can connect a single optical fiber together (simplex) or two optical fibers together (duplex). Most adapters are female at both ends, which are used to connect two cables. Connecting two cables together allows two devices to communicate from a distance through a direct connection with fiber optic lines. Some are male to female, and they are usually plugged into ports on the device.
Conclusion
Fiber optic adapter provides convenience for fiber optic cable connection. Fiber optic adapter plays a vital role in aligning a single fiber in one cable with the fiber in another cable. If the fibers are not aligned correctly, loss will occur at this mating point. Optical fiber adapter greatly improves the work efficiency.
