Abstract

The invention provides an optical fiber dividing box which comprises an aluminum alloy box body 1, an anti-corrosion coating layer 2, a radiation protection coating layer 3 and a painting layer 4 from inside to outside. The optical fiber dividing box is simple in structure, low in cost, rusting is not easy, and radiation can be effectively prevented.

Description

technical field [0001] The invention belongs to the field of optical fiber equipment, in particular to an optical fiber splitting box used in an optical cable network communication system. Background technique [0002] The optical fiber distribution box has become the mainstream way of broadband access, and the demand for the distribution box is also increasing. Its task is to carry the distribution optical cable, connect the household optical cable, and complete the distribution and scheduling of the optical cable. At the same time, since the core technology of the PON (Ethernet Passive Optical Network) network is the application of optical splitting technology, the distribution box installed with optical splitters will undoubtedly become one of the most important devices in the PON network. [0003] At present, most of the optical fiber distribution boxes on the market are mostly made of metal or plastic. Metal distribution boxes have disadvantages such as large size, high...
