Description

Technical Field

[0001] This utility model relates to the field of terminal box technology, and in particular to a convenient plug-in single-mode or multi-mode terminal box. Background Technology

[0002] In fiber optic communication networks, terminal boxes are critical devices for fiber optic connection, distribution, and protection, widely used in data centers, telecommunications networks, and intelligent buildings. The main functions of a terminal box include fiber optic splicing, storage, splitting, and port management to ensure the stability and reliability of signal transmission. Currently, fiber optic terminal boxes on the market are mainly divided into single-mode and multi-mode types, suitable for long-distance communication and short-distance high-speed data transmission, respectively. However, existing terminal boxes still have certain problems in terms of installation, maintenance, and flexibility. Traditional terminal boxes typically use screw-fixed or snap-fit ​​enclosed structures, requiring disassembly of the outer shell for fiber optic patch cord insertion / removal or maintenance, which is cumbersome and affects construction efficiency. Therefore, we have redesigned a convenient pluggable single-mode / multi-mode terminal box. Utility Model Content
