Embodiment 1

[0027] This embodiment provides an optical fiber distribution box, including a box body 31 and a cover plate 30, the cover plate 30 can be fastened to the box body 31 to form a cavity, figure 1 A schematic diagram of its internal structure is given. As shown in the figure, an optical fiber adapter 12 is arranged in the box body 31. Preferably, the optical fiber adapter 12 is a 72-core optical fiber distribution device. One side of the optical fiber adapter 12 in the box body 31 is provided with an optical fiber fusion splicing tray 32, and the direct melting plate 11 and the pair of remaining optical cables on both sides of the direct melting plate 11 are arranged on the optical fiber fusion splicing tray 32. The fiber winding reel 10 for disk storage; the optical cable enters the box body 31 through the wire inlet 16 and is welded with the distribution pigtail on the direct melting plate 11, and the distribution pigtail is connected to the jumper through the optical fiber adap...

Embodiment 2

[0030] This embodiment makes the following improvements on the basis of Embodiment 1. The optical fiber splicing tray 32 is detachably arranged on the bottom plate of the box body 31 through a fixing member, and the fixing member can be selected as bolts and nuts or other type of fixture. On the side of the optical fiber fusion splicing tray 32 close to the wire inlet 16, a holder 1 for fixing the optical cable is provided, such as figure 1 As shown, the deck 1 can be selected to be 8.

[0031] In this embodiment, the optical fiber fusion splicing tray 32 is detachably arranged on the bottom plate of the box body 31, so that the optical fiber fusion splicing position can be flexibly selected according to the actual situation. If necessary, the optical fiber fusion splicing tray 32 can be removed to select the most fiber-saving position. Fusion splicing can save at least 1 meter to 1.5 meters of optical fiber, saving costs.

[0032] In addition, in order to effectively preven...

Abstract

The invention discloses an optical fiber distribution case which comprises a case body and a cover plate. The cover plate can be buckled on the case body to form a cavity body. An optical fiber adapter is arranged inside the case body. An optical fiber fusion welding disc is arranged on one side of the optical fiber adapter and is provided with a straight welding plate and fiber winding discs which are arranged on two sides of the straight welding plate and stores remaining optical cables in a disc mode. Optical cables enter the case body through a cable inlet to be connected with a distribution tail fiber on the straight welding plate in a welding mode. The distribution tail fiber is connected with a jumper tail fiber through the optical fiber adapter, and the jumper tail fiber is output out of the case body through a cable outlet. An X passive optical network (XPON) optical fiber access device and an optical branching device are arranged on the other side of the optical fiber adapter. The optical fiber distribution case can integrally install devices of an operator and part of devices of electric power telecommunication inside the optical fiber distribution case, and considers communication device installation needs needed by a 'three-in-one network' of electric power telecommunication and an operation enterprise. The optical fiber distribution case can achieve telecommunication service access, and is suitable for a fiber to the home project of a small high-rise area and a high-rise area.

Description

technical field [0001] The invention relates to an optical fiber distribution box for OPLC (Optical Fiber Composite Low-voltage Cable). Background technique [0002] In recent years, with the development of smart grids, the State Grid Corporation of China has proposed the concept of "four-network integration", that is, the organic integration of power grids, telecommunication networks, broadcasting networks, and the Internet. Since OPLC combines the functions of optical fiber communication and power transmission, compared with single-function transmission cables, it has the characteristics of high reliability data transmission, low price, convenient connection, and the integration of optical cables and power lines without secondary wiring. OPLC realizes fiber-to-the-home, solves the problem of repeated investment in the construction of optical cable lines, and reduces "black pollution". As an important access device connecting users and the network, optical fiber distributi...
