Ground imbedded high-capacity optical cable connection box

Abstract

The invention relates to a underground large capacity optical cable connecting box, which belongs to the optical cable transmission technique field. The connecting box includes a box body and a seal cover, and a cable inlet, an optical cable routing bracket, an optical cable core-strengthening fixed card, an optical fiber fixed card, a guide fiber groove, a fusion fiber tray, a jumping wire coil fiber case and the like are arranged in the box body. The cable inlet, the optical cable core-strengthening fixed card and the optical fiber fixed card are respectively positioned on the sidewall of the upper part of the box body. The optical cable routing bracket is positioned on the around wall of the upper part of the box body, and the fusion fiber tray is positioned on two opposite walls in the box body. The guide fiber groove is connected between the optical cable core strengthening fixed card and the fusion fiber tray, and jumping wire coil fiber case is arranged at one side of the fusion fiber tray. The connecting box has the advantages that: the construction is simple and swift, the construction can be easily executed in downtown flourishing sections, can not affect the traffic, and can effectively reduce the occupied land area of downtown streets. The underground connecting box can be prevented from damaging, so as to ensure the secure communication. The connecting box has large capacity, and can be applied to the convergence layer and the optical cable inlet and outlet layers where optical fiber is centralized.

Description

technical field [0001] The invention relates to an underground large-capacity optical cable transfer box, which belongs to the technical field of optical cable transmission. Background technique [0002] The optical cable transfer box is an interface device used for the backbone optical cable and distribution optical cable node in the optical fiber metropolitan area network, which can realize the fusion splicing, disk storage, distribution and scheduling of optical fibers. With the increasing opening of the telecommunications market, operators are stepping up the construction of their own optical cable metropolitan area network. The large-scale construction of optical cable metropolitan area network will greatly increase the demand for optical cable transfer boxes. Existing fiber optic cable transfer boxes are generally placed on the ground, which has the disadvantages of affecting city appearance, affecting traffic, occupying land resources, and not meeting the requirements...

AI Technical Summary

Problems solved by technology

The disadvantage of the optical cable transfer box is that it is inconvenient to maintain and there is no accident warning system, so once a damage accident occurs, the maintenance takes a long time

Moreover, the communication capacity is small, which cannot meet the actual needs
