The optical fiber connector is a device for detachable (movable) connection between an optical fiber and an optical fiber. It precisely connects the two end faces of the optical fiber so that the light energy output by the transmitting fiber can be coupled to the receiving fiber to the maximum. And to minimize the impact on the system due to its intervention in the optical link, which is the basic requirement of optical fiber connectors. To a certain extent, fiber optic connectors also affect the reliability and performance of the optical transmission system

1,Use a fiber cleaver to get a clean fiber end face
Fiber optic connectors are used at the end of fiber optic cables to realize the connection between fiber coupling devices (a removable fiber optic connector). Its function is similar to that of an electronic connector.
Generally, the connector assembly includes one connector and two connector plugs, where each optical fiber is inserted into one connector plug. The process of inserting the optical fiber into the connector plug is more elaborate than most electronic connection methods:
2,Carefully insert the fiber port into the connector plug.
Then carefully insert the fiber port into the connector plug. The position of the optical fiber needs to be very accurate, and the end face of the optical fiber cannot be damaged in this process. Depending on the type of optical connector used, the subsequent processes required are also different, usually including cleaning the plug and polishing the optical fiber tip. Most connectors require glue or other adhesives to fix the optical fiber.
If you use a very sensitive system, you need to measure the insertion loss and return loss, otherwise it will have an impact on the subsequent devices.
These terminal kits are usually used in industry, but they can also be used in the field with suitable devices. Of course, a relatively clean environment is required.
3,Protect the inserted fiber
Although the fiber optic connector can protect the inserted fiber, this protection is not complete, for example, it is not moisture-proof. Therefore, the connector needs to be placed in the protective shell. The sealed outer cover can prevent moisture and dirt, and can also prevent heat dissipation (for example, the loss of the connector when it is working with power). The dust cap is usually covered when the connector is not inserted into the device.
Simply put, one end of the optical fiber transceiver is connected to the optical transmission system, and the other end (user end) comes out with a 10/100M Ethernet interface. Optical fiber transceivers are used to achieve photoelectric signal conversion. The main principle of the optical fiber transceiver is realized by photoelectric coupling, and there is no change to the signal encoding format
