Abstract

The invention relates to an optical cable cross connection cabinet special for FTTB (fiber to the building) and FTTH (fiber to the home), which is used as an interface of a trunk optical cable and an optical distribution cable specially for EPON and GPON systems of a fiber access network. The optical cable cross connection cabinet comprises a base (8), a cabinet body (19), a fiber storage chamber(16), a fusion distribution integrated single-disk mounting frame (21), a straight-through device (12), an optical cable fixing device (7), a fusion distribution integrated single disk (14), a straight-through optical cable (9), a homing optical cable (10), a feeder optical cable (11), an optical cable fixing device (7), a straight-through device (12), a cable manager (17) and a right cable passing ring (15). The optical cable cross connection cabinet is characterized in that the optical cable cross connection cabinet also comprises an additional fusion distribution integrated single disk (13), an optical splitter frame (3), an optical splitter (6), a left cable passing ring (1) and an optical splitter tail fiber (2). One optical cable cross connection cabinet can cover 288 users by addingone fusion distribution integrated single disk and the optical splitter frame, and achieve the aim of increasing the quantity of covered users; and 165 jumper wires are saved during full configuration by adopting a tail fiber type optical splitter, and the investment cost can be greatly reduced.

Description

(1) Technical field [0001] The invention relates to an optical cable transfer box. It is specially used in the EPON and GPON systems of the optical fiber access network as the interface between the backbone optical cable and the distribution optical cable. Achieve fiber-to-the-home and fiber-to-the-building. It belongs to the technical field of optical devices. (2) Background technology [0002] The optical cable transfer box is the interface device for the backbone optical cables and distribution optical cables in the GPON (New Generation Ethernet Passive Optical Network) and EPON (Ethernet Passive Optical Network) optical fiber access network, with a capacity of 288 cores. Realize the fusion splicing of optical fibers, the storage of optical fibers, the distribution of optical fibers and the passing connection of optical cables. At present, the construction of communication is being vigorously carried out, especially the optical fiber to the home and the optical fiber t...
