In recent years, in the actual work of optical communication construction, after comparing the use of several products, we believe that the selection of fiber optic distribution frame should focus on the following aspects.
A. CORE CAPACITY
A fiber optic distribution frame should be able to make the number of cores of fiber optic cable on the shelves of the bureau reach the maximum level, and if possible, the interconnection of more than a few fibers optic cable on one rack to facilitate the deployment of optical paths. At the same time, the wiring frame capacity should correspond to the common cable core series, so that it can reduce or avoid the waste of fiber optic distribution frame capacity due to improper matching.
B. THE TYPE OF FUNCTION
Fiber optic distribution frame as the terminal equipment of the fiber optic cable line should have four basic functions.Fixed function – After the optical fiber cable enters into the rack, its outer sheath and strengthen the core should be mechanically fixed, ground protection components need to be added, end protection should be processed, and optical fiber must be grouped and protected.Capacitive splicing – Take the function fiber optic cable out of the fusion and put it together with the tail cable, coiled storage the excess fiber, and protect the fusion splice.Deployment function – The connector attached to the pigtail cable is plugged into the adapter, to achieve optical docking to the optical connector on the other side of the adapter. The adapter and connector should be able to plug and unplug flexibly; while the optical path can be freely deployed and tested.Storage function can provide storage for the rack between the various cross-connected optical connection line, so that they can be placed neatly and regularly. The fiber optic distribution frame should have the appropriate space and way to make this part of the optical connection line alignment clear, easy to adjust, and can meet the minimum bending radius requirements.
