Specially designed to improve the mechanical strength of the welding point and ensure the reliability of fusion; The optical transmission characteristics of the optical fiber are not affected; the method of use is simple and safe, and the risk of negative impact on the optical fiber during use is reduced; Monitor the condition of the fiber weave at any time; The inner seal is completely sealed, so that the weld joint has good high temperature and high humidity. Features: Design fiber optic splice protection components consisting of cross-linked polyolefin, tube melt and reinforced stainless steel wire.1. It does not affect the optical conductivity of the fiber.2. Protect the connection point and increase the mechanical strength.3. Simple operation, reducing the risk of fiber damage during installation.4. The transparent housing makes it easy to see the status of the fiber optic connection.5. The sealing structure makes the connection have good temperature and humidity resistance.
