Optical fibre distribution frame and wiring method in optical fibre distribution frame

Abstract

The invention relates to an optical fibre distribution frame. The optical fibre distribution frame comprises a rack, wherein the rack comprises a jump fibre operation surface, a jump fibre storage side, an optical cable end-forming surface, an optical cable lead-in side, and a front-and-rear fibre feeding side; the jump fibre operation surface and the optical cable end-forming surface are oppositely arranged at the both sides of the rack; a plurality of second inter-frame jump fibre horizontal fibre-feeding grooves for providing a horizontal routing channel for the inter-frame jump fibres are formed in the optical cable end-forming surface, and the second inter-frame jump fibre horizontal fibre-feeding grooves are distributed at intervals along the longitudinal direction of the rack; a plurality of front-and-rear fibre feeding grooves for the feeding of inter-frame jump fibres along the front-and-rear direction of the rack are arranged in the front-and-rear fibre feeding side at intervals; thus when the inter-frame jump fibres arrive at one side of the optical cable end-forming surface through the front-and-rear fibre feeding grooves, fibre feeding is carried out by the second inter-frame jump fibre horizontal fibre-feeding grooves of the adjacent optical fibre distribution frames to realize inter-frame fibre jumping.

Description

technical field [0001] The invention relates to the field of optical fiber communication, more specifically, to an optical fiber distribution frame and a wiring method in the optical fiber distribution frame. Background technique [0002] With the development of FTTX, the number of optical fibers in the computer room is continuously increasing, and higher requirements are placed on the manageability of fiber jumpers, which makes the use of traditional optical distribution frames (Optical Distribution Frame, ODF) a great challenge. . At the same time, with the increasing shortage of computer room land, the expensive use of space in the computer room also puts forward better capacity requirements for optical fiber distribution frames. The appearance of optical fibers with small curvature radius provides convenience for further increasing the capacity of optical distribution frames. However, most of the optical fiber distribution frames using light with such a small radius of...

Problems solved by technology

However, most of the optical fiber distribution frames using light with such a small radius of curvature are in the research and development stage; in addition, the increase in the capacity of the optical fiber unit box will greatly increase the number of optical fiber cables and jumper fibers, resulting in more dense and complex wiring and fiber routing. , which brings inconvenience to the operation

[0003] The traditional optical fiber distribution frame is generally operated on one side, with single function, small capacity and low density; in addition, the fiber jumper between the racks needs to pass through the fiber rack at the top of the machine room, and a large amount of space needs to be reserved in the rack It is used to store redundant fiber jumpers, and the production cost is high; moreover, this kind of fiber distribution frame has complex fiber jumper wiring and many crossovers, which brings inconvenience to installation, maintenance and management
