How to use fiber optic flanges

　　fiber optic flanges, also known as fiber optic butt flanges, are components that connect optical fibers. They can be the same type of fiber optic connector or different types. The use of fiber optic flanges mainly includes the following steps:

　　First, the preparation stage

　　Cleaning Fiber Optics and Flanges:

　　Before inserting the flange, the end face of the ceramic core of the fiber core should be wiped with gauze soaked in anhydrous alcohol, and the dust should be blown off with a blow-up balloon (or medical "ear wash ball"). The wiped fiber end face should not touch any objects during the insertion of the light flange.

　　The flange also needs to be cleaned. Use a rod cleaner dipped in alcohol, pass through the coupling hole, insert it into the flange, and wipe it clean. Then use canned air to blow off the dust in the flange.

　　Check the fiber optics and flanges.

　　Make sure that the fiber is not bent, folded, or damaged. Excessive twists and turns can break the fiber's core.

　　Check that the ceramic sleeve of the flange is in good condition and free of chipping or cracks.

　　Second, the connection stage

　　Fiber Insertion Flange:

　　Align the ceramic end face of the fiber with the ceramic sleeve of the flange, and then gently insert it. During the insertion process, you can gently turn it back and forth while pushing in until it is inserted into place.

　　Different types of fiber optic connectors (such as ST type, FC type, SC type, etc.) have different insertion and locking methods, and they need to be operated according to the specific connector type. For example, ST type fiber optic connectors are locked and connected through the bayonet of the plug socket, FC type is connected by tightening the plug on the flange like a screw, while SC type connectors are square and can be inserted directly.

　　Lock the fiber optic connector:

　　For fiber optic connectors that need to be locked (e.g. FC type), after the fiber is inserted into place, it needs to be locked according to the locking method of the connector (e.g. rotary locking, bayonet locking, etc.) to ensure a stable and reliable fiber optic connection.

　　III. Testing and maintenance

　　Test connection:

　　After the connection is completed, use a fiber optic tester to test to ensure that the fiber optic connection is normal and there are no light attenuation or other issues.

　　Maintenance flange:

　　Regularly clean and inspect the flange to ensure that its surface is clean, dust-free, and oil-free.

　　Check whether the bolts, gaskets and other components of the flange are loose or aging, and replace or repair them in time if necessary.

　　For cable transfer boxes operating in humid and humid environments, anti-corrosion treatment is required to extend their service life.

　　IV. Precautions

　　Avoid violent operations:

　　When connecting the optical fiber, avoid violent operation to avoid damaging the ceramic sleeve of the optical fiber or flange.

　　Protection of optical fibers and flanges:

　　When the optical fiber and flange are not connected, they must be covered with corresponding protective covers to prevent dirt from entering or contaminating the end face of the optical fiber.

　　Ensure connection accuracy:

　　When connecting optical fibers, it is necessary to ensure the concentricity of the two optical fibers in alignment to ensure the connection accuracy and the tranSMission quality of the optical signal.

　　In summary, the use of fiber optic flanges requires following certain steps and precautions to ensure the stability and reliability of fiber optic connections. In actual operation, it should be operated according to the specific fiber optic connector and flange type, and follow relevant standards and specifications.
