Description
Technical Field
The invention belongs to the technical field of optical cables, and particularly relates to an optical cable node connecting device.
Background
The information disclosed in this background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.
Fiber To The Home (FTTH) is a transmission method of optical fiber communication. In particular, FTTH refers to installation of an Optical Network Unit (ONU) at a home subscriber or an enterprise subscriber. Similar to the 'cross-connection wiring mode' of all-plastic communication telephone cables, an optical Fiber To The Home (FTTH) distribution network (ODN) is divided into a trunk optical cable subsystem, a distribution optical cable subsystem and a home-entry optical cable terminal subsystem. The main optical cable subsystem is an optical cable distribution system connected between subscriber optical cable cross-connecting boxes from a local side optical distribution frame ODF connected with an optical fiber access device OLT. In the optical fiber distribution device at the two ends, the optical cables are terminated in a hot melting mode, and the optical cables are spliced with the tail optical fibers of the optical cables. The distribution cable subsystem refers to the fiber optic cable from the optical distribution cabinet to the "fiber optic distribution cabinet" within the customer premises. This is an optical distribution tray in which the input cables are directly connected "back-to-back" to the output cables, and splitter devices are typically also located therein. An optical splitter is an "optical fiber multiplexing device" that "multiplexes" channels of a single-core optical cable into multiple channels, and the splitting ratio is generally 1:16;1:32 and 1: and 64 types. The optical splitter (OBD) can consider different types of optical splitters according to the arranged position, and mainly comprises three types of 'box type fiber output optical splitters', 'tray type optical splitters' and 'inserting piece type end forming optical splitters'; the types of the optical cable tail fiber plugs are SC type square head optical fiber plugs.
In the prior art, the light splitter is generally installed in a tapping box, and the tapping box generally has dustproof and waterproof functions. Before the optical cable and the optical cable tail fiber are welded, the tapping box needs to be opened, the optical cable is sent into the tapping box from the center hole at the bottom of the tapping box to be welded, and the tapping box needs to be closed after the optical cable and the optical cable tail fiber are welded. The following problems exist in actual welding: firstly, for construction convenience, some constructors omit the step of sending the optical cable into the tapping box from a central hole at the bottom of the tapping box, so that the tapping box cannot be closed after fusion splicing; secondly, different constructors perform welding operation at different time intervals, so that the problems that the optical cable welded before is accidentally broken and the like are likely to be caused; thirdly, during later maintenance, due to the fact that the wiring harnesses in the distribution box are messy, the wiring harnesses are cut off in a cutting mode; fourthly, welding/quick connection has certain technical content and time investment, and the overall performance is different from person to person, so that the construction cost is high, the efficiency is low, and the maintenance difficulty is high. How to solve the technical problems is a technical problem to be solved urgently in the field.
