These common equipment are generally used in long-distance communication transmission projects. Because the outdoor adopts the form of overhead optical cable installation, there will be remaining communication optical cables between each optical cable terminal. There is a square black device on it, which becomes an optical cable splice box. The number of optical fibers on both sides and the type of optical cable must be the same to ensure the normal use of the optical cable in the future; and the optical cable terminal box refers to the end of the optical cable and enters the equipment transmission. Among them, each optical cable can be divided into several optical fibers, and the optical cable is transformed into a central equipment for transmitting optical fibers, and becomes an optical cable terminal box. But the same is attributed to the most basic and common transmission medium in optical cable transmission engineering.
We also mentioned above that the terminal box and the splice box are mainly different in physical characteristics. This also causes the two different scopes of application: the optical cable terminal box is a device in which the ends of many optical cables are connected to each other in the optical switching connection, and its quality will directly affect the stability of optical signal transmission. Now the common optical cable terminal box has been further adjusted according to the number of optical cable cores. Connected equipment, outdoor long distance or encountering fiber optic cable damage, can only maintain the continued use of the fiber optic cable through the splice box.
In addition, in terms of cable prices, the two also have differences. The price of communication optical cable splice box is higher than that of optical cable terminal box. The price of 24 new optical cable terminal boxes on the market is around 30 yuan, while the price of optical cable splice boxes ranges from 40 to 50 yuan. The fundamental reason is that the optical cable splice box belongs to the equipment that is connected on all sides. When dealing with emergency optical cables, it is necessary to finely connect the optical cables on both sides. However, the optical cable terminal box only needs to weld the inner cable core in the reel. It saves a lot of work in optical cable fusion, and the price will naturally be lower than that of the splice box.
