Fiber optic construction method

In practical applications, the connection between optical fibers is generally carried out using two methods: hot fusion and cold fusion.
Hot melt welding method
The high voltage arc of the fiber optic fusion splicer is used to melt and connect two optical fibers. This method was generally used in long-distance communication construction in the early days. However, with the increasing demand for network speed and the rise of fiber optic cables entering households, the hot fusion splicing method is also used for short distance fiber optic laying construction (such as small area broadband networks and fiber optic cables entering households), and has become the mainstream fiber optic construction method internationally.
Cold joining method
The cold connection method is relative to the hot fusion method, which means that the optical fiber is connected or connected to the optical communication equipment by using the optical fiber cold connector instead of high-voltage arc discharge to melt the optical fiber.
