Fusion splicing can withstand a wide range of temperatures. Dust and other pollutants are kept away from the optical path by fusion splicing. If too much heat is applied to melt the fiber optic cable for termination, the connection will become brittle and cannot be used for a long. While fiber optic cable is remarkably resilient, temperature changes do impact its performance—sometimes subtly, sometimes critically. The effects aren't electrical, but they are very real: rooted in thermodynamics, material science, and waveguide physics. Your fibers may not be connected. fiber - Do low temperatures cause problems installing new optical wiring or fixing broken optical cables by splicing? - Network Engineering Stack Exchange Do low temperatures cause problems installing new optical wiring or fixing broken optical cables by splicing? One of our supplier reported big. This technique involves using localized heat to melt the ends of two optical fibers and fuse them together. For example, the refractive index of glass, which determines the speed and direction of light propagation in the fiber.
