The series of fiber optic terminal boxes are auxiliary equipment for terminal wiring in optical fiber transmission and communication networks, which are suitable for the direct and bifurcation connection of indoor fiber optics and protect optical fiber connectors.
The fiber optic terminal box is mainly used for the fixing of the fiber optic terminal, the fusion of the fiber optic and the tail fiber and the reception and protection of the residual fiber.
Integrated cabling system fiber optic terminal box
The fiber optic terminal box is mainly used for the fixing of the fiber optic terminal, the fusion of the fiber optic and the tail fiber and the reception and protection of the residual fiber.
The fiber optic terminal box is also called the optical fiber terminal box, which is a box for protecting the fusion of the fiber optic and the tail fiber at the terminal of the fiber optic. it is mainly used for the straight-through connection and branch connection of the indoor fiber optic and the fixing of the fiber optic terminal. It plays the role of tail fiber disk storage and protection joint.

Environmental requirements
Service life
The normal service life of the optical fiber box is 20 years, the premise is that the quality must pass, and the optical fiber box works under normal temperatures and humidity.
Main functions
Structure
The fiber optic terminal box is composed of a cover, an internal component and an optical fiber connector protection part.
1. Cover
2. Internal components
The internal components should include the following parts:
Used for the fixing of fiber optic sheath, fiber optic reinforcement and tail fiber. Its performance is not affected. There shall be insulation between the fiber optic metal components, and between the fiber optic metal components and the shell and internal metal components.
Used for sequentially storing optical fiber connectors and remaining optical fibers, optical fiber connectors should be firmly and reliably fixed on the fiber collecting disc.
Used for electrical connection or disconnection of metal components in fiber optic.
Used for high voltage protective grounding. If a high voltage protective grounding device is adopted, the cross-sectional area of the connecting wire connected to the metal strengthening core and metal sheath in the fiber optic should be more than 6 square millimeters, and the cross-sectional area of the connecting terminal connected to the ground should be greater than 35 square millimeters, and there is an obvious grounding sign at the ground.
3. cal fiber connector protection parts
Heat shrinkable protection tubes and clamps can be used for the protection of optical fiber joints.
Electrical performance
Function
The function of the fiber optic splice closure is to connect two pieces of fiber optic.
The terminal box is the place where the end of the fiber optic is connected, and then connected to the optical switch through the optical jumper.
As a result, the terminal box is usually installed in a 19-inch rack and can accommodate a large number of fiber optic cable ends.
The function of the fiber optic splice closure is to connect two pieces of fiber optic.
The terminal box connects the fiber optic with the tail fiber for protection.
In practice, the terminal box can be used as an indoor fiber optic splice closure, but it is rarely used as a terminal box for different purposes.
The handover box can be divided into fiber optic handover box and cable switchbox.
Their functions are used in the front-end wiring of users.
The fiber optic splice closure, is also known as the fiber optic junction box. Its function is to protect the fiber optic connector from external damage.
The distribution frame is also divided into fiber optic distribution frame and cable distribution frame, which also acts like a transfer box, but it is used in the computer room of the operator.
Application.
As the carrier of information transmission and optical fiber hardware as the medium of information transmission, fiber optic terminal box has become an important pillar of modern communication.
The fiber optic terminal box technology has experienced several decades from the theoretical proposal to the technical realization in the engineering field, and then to the realization of high-speed optical fiber communication today. the birth and further development of optical fiber communication technology is an important reform in the history of information communication.
fiber optic terminal box is widely used in local telephone, rural telephone network system, data and image transmission system, CATV cable TV series, for indoor fiber optic straight-through connection and branch connection, and plays the role of tail fiber disk storage and protection connector. it is made of cold-rolled steel plate electrostatic spray molding, reasonable design structure and beautiful appearance can fix the fiber optic strengthening core in the terminal.
Installation requirements
The optical cable terminal box is equipped with comprehensive installation parts. The specific installation steps are as follows:
