The optical fiber splice closure connects two or more optical cables together, and has the connection part of the protective component. It is a must use in the construction of optical cable line engineering, and it is one of the very important equipment. The quality of the optical cable connector box directly affects the optical cable The quality of the line and the service life of the optical cable line.
According to the shape and structure, it can be divided into two types: hat type optical cable joint box and horizontal optical cable joint box. According to the optical cable laying method, there are overhead, pipeline (tunnel) and direct buried types.
