Basic introduction of optical cable splice box

The types of optical cable splice boxes can be divided into cap-type optical cable joint boxes and horizontal optical cable joint boxes according to the shape and structure. According to the laying method of optical cable, it can be divided into overhead, pipeline and direct burial. According to the connection method of optical cable, it can be divided into two types: straight-through connection and branch connection. According to the sealing method, there are heat shrinkable sealing type and mechanical sealing type.

Optical cable splice box is a connection part that connects two or more optical cables together and has protective parts. It is used in the construction of optical cable lines and is one of the very important equipments. The quality of the optical cable junction box directly affects the quality of the optical cable and the service life of the optical cable.

The optical cable splice box belongs to the mechanical pressure sealing splice system, which is a splice protection device that provides optical continuity, sealing and mechanical strength between adjacent optical cables. It is mainly used for straight-through and branch connections of various structural optical cables in overhead, pipeline, direct burial and other laying methods.

The optical cable splice box is the place where the end of the optical cable is connected, and then connected with the optical switch through the optical fiber jumper, preventing heat, cold, light, oxygen and microorganisms in nature, and has excellent mechanical strength, solid optical cable junction box shell and main structure It can withstand harsh environmental changes, and at the same time play the role of flame retardant and waterproof, so that vibration, shock, cable stretching, twisting, etc. are protected.

The optical cable splice box is suitable for the straight-through and branch connection of various structural optical cables in various laying methods such as overhead, pipeline, and direct burial. Optical cable splice boxes are also suitable for the connection of structured optical cable terminal rooms. Optical cable joint boxes are usually suitable for indoor or non-open outdoor use, and are not suitable for outdoor use.
