Our engineers point out that the connection between fiber optic cables and fiber optic connectors is currently mainly divided into three types: factory prefabrication, on-site cold connection, and on-site fusion, as follows:
1. Factory prefabrication: This method is the most reliable and long-lasting method, mainly based on the length required by customers. Epoxy resin is used to ensure the direct fixation of optical fibers and fiber connectors. The advantages are good tensile performance, stable data, long service life, good adaptability to the environment, and overall low price. The disadvantages are long production cycles and the lack of professional equipment during on-site construction, which cannot be cut arbitrarily;
2. On site cold connection: This method is a consistent method commonly used in telecommunications wiring construction. The length is confirmed on site based on the distance between the corridor box and the user, and the connection between two optical fibers is ensured through metal or non-metallic V-shaped grooves. The cold connection connectors used are prefabricated by the factory, with the advantages of convenient on-site construction, short connection time, and generally, if there are no abnormalities in the cold connection connectors, there will be no excessive loss Cold joint failure: Cold joint connectors can be reused, but their disadvantages include unstable performance, poor pre made tensile and pulling performance, high requirements for construction personnel's skills, and poor adaptability to the environment;
3. On site welding: This method is a consistent method commonly used in mobile wiring construction. Similar to cold welding, it confirms the length on site and is manufactured on site. The hot melt connectors used are also prefabricated in the factory, and the connection between two optical fibers is ensured through the discharge of the welding machine. The advantages are convenient on-site construction, interrupted connection time, better adaptability to the environment, and better tensile performance than cold welding. The disadvantage is that professional equipment (welding machine) needs to be used, The price is relatively high, and generally the construction team is not equipped. At the same time, the requirements for personnel skills during construction operations are higher than for cold welding, and the failed fusion connectors cannot be reused.
So according to the reliability ranking, on-site prefabrication is the best, followed by on-site welding, and cold welding is the bottom; According to convenience, cold welding is the best, followed by fusion welding, and on-site prefabrication is the bottom.
