High-power output optical fiber coupler

Abstract

The invention relates to the field of optical fiber couplers, in particular to a high-power output optical fiber coupler which comprises a shell, a hot melting mechanism is arranged on the shell, the hot melting mechanism abuts against a splitting mechanism, the splitting mechanism is arranged in the shell, and the hot melting mechanism abuts against the splitting mechanism. According to the optical fiber hot melting device, an optical fiber powder material in the hot melting mechanism can be detached through the arranged detaching mechanism, so that the optical fiber powder material enters the interior of the shell, when the hot melting mechanism carries out hot melting, the hot melting efficiency can be rapidly improved, and connection of optical fiber contact points after hot melting is firmer; the optical fiber surface and the shell are sealed more firmly, a good sealing effect is achieved, the surface of the optical fiber can be sealed through the arranged fastening mechanism, the fastening mechanism can further extrude the surface of the optical fiber while fastening the optical fiber, and therefore the fastening mechanism and the optical fiber are sealed.

Description

technical field [0001] The invention relates to the field of optical fiber couplers, in particular to a high-power output optical fiber coupler. Background technique [0002] When coupling the existing optical fiber couplers, it is generally necessary to use a hot-melt device to couple the fibers, and after the coupling is completed, the fibers are taken out from the hot-melt device. When connecting, it is difficult to align the end face of the optical fiber, and it is difficult to flatten the end of the optical fiber, so that the optical fiber needs to be flattened before the butt joint, which reduces the welding efficiency, and it is easy to make the joint after welding. When the fiber optic connector is not protected in water, the fiber optic connector is easily corroded, especially the corrosion phenomenon of the fiber optic connector located in seawater is more serious, which reduces the service life of the fiber. SUMMARY OF THE INVENTION [0003] In view of the prob...

Problems solved by technology

[0002] When the existing optical fiber coupler is coupled, it is generally necessary to use a thermal fusion device to couple the optical fiber, and then take the optical fiber out of the thermal fusion device after the coupling is completed; and there are many optical fibers directly connected by the coupler, and the coupler is in the When connecting, it is difficult to align the end face of the optical fiber, and it is also difficult to flatten the end of the optical fiber, so that the end face of the optical fiber needs to be flattened before the butt joint, which reduces the welding efficiency, and it is easy to make the joint after welding. When the fiber optic connector is in water without protection, the fiber optic connector is easily corroded, especially the fiber optic connector in seawater is more severely corroded, which reduces the life of the fiber
