Abstract

A high-density unit box comprises a box body (1). The box body comprises a module region (3) used for installing function modules (2) and a fibre storage region (4) used for coiling and feeding remaining fibres. The module region is provided with a module bracket (30), a plurality of function modules are inserted onto the module bracket in parallel, and the function modules are slidably connected to the module bracket. In the high-density unit box, because the box body is internally divided into the module region and the fibre storage region, and the fibre storage region uses male-tab-type function modules, the function modules can be pulled out for maintenance, thereby solving the operation problem of a front panel after the capacity is increased. The function modules can be exchanged because of having the same installation dimension, and can meet various demands. The existence of the fibre storage region solves the problem of coiling and feeding remaining fibres, which makes it convenient to operate and maintain and facilitates the management of the remaining fibres.

Description

High density unit box

Technical field

The present invention relates to a unit box in the field of optical communication, and more particularly to a high density unit box.

Background technique

With the development of fiber-to-the-home FTTH and triple play, it is necessary to integrate the optical fiber hardware of the exchange with the external optical cable and the optical fiber hardware. The original DSL and fiber/coax hybrid network can generally support 24 to 48 fiber optics, and in the FTTH network, the regional convergence point (LCP) junction box is used in time, and often the exchange has hundreds or even thousands of fiber ports. In FTTH mode, each user can access either from a neighboring LCP splitter box or directly from the exchange. Regardless of which starting point is a good support for future broadband demand growth, based on this, deploying a fiber-optic network model that supports all home users in the target area is primarily based on total cost.

The total cost includes not only the cost of the cable, but the most important is the cost of laying the cable. Whether it is overhead or buried, the use of ribbon cable is most beneficial to improve efficiency and reduce installation costs. Firstly, in order to provide a manual switching mechanism between the feeder ring and the distribution ring, most of the ring network is used, and the cross-connection method is adopted at the central office, and the number of cores on the corresponding fiber distribution frame is multiplied. If ordinary fiber optic cable is used, the corresponding laying cost will be increased on the one hand, and the pipeline resource will be saved on the other hand. Secondly, the ribbon cable used in the end can be a 4-core, 8-core or 12-core set at the end of the terminal. At the same time welding, a large number of less construction time; if you want to further reduce the opening time, you can also use the factory pre-wired cable to open; and if the area of the central office service is relatively small, you can directly connect the user to the central office rack on.

It can be seen that after the large-capacity ribbon cable is used, if the central office space is constant, we must try to increase the capacity of the distribution frame, and the field termination of the ribbon cable needs to be equipped with the fusion wiring module on the rack; To use the pre-termination method, you need to configure the pre-termination module on the rack. You need to configure the optical splitter module to connect the user directly to the central office rack. If necessary, you need to meet the requirements of the triple-network convergence. Multiplex module.

Under, it cannot be integrated with the main device.

The existing unit box usually adopts a welded wiring separation structure or an integrated module structure, and mainly has the following disadvantages: 1. The density of the adapter port of the box body is small, and the operation space for the operator to normally plug and unplug the connector is difficult, resulting in difficulty in upgrading the capacity. 2, single function, can not adapt to the use of a variety of value-added modules such as fusion wiring, splitting, pre-termination, etc. under the all-optical network; 3, need to add additional fiber-optic space when mixed with the main equipment, the integration is not high .
