How to choose the right distribution frame?
The optical fiber distribution frame is used to accommodate the optical fiber and the optical fiber activity transfer component, its role is mainly used to fix and receive the optical fiber, end the optical fiber and install the optical fiber coupler, but also can protect the optical fiber connector, prevent it from being damaged, generally speaking, is a protective device.
The optical fiber distribution frame on the market is the same as many products, they have common characteristics and different points, different shapes and different specifications. Each manufacturer has its own unique style and key features. So when we choose optical fiber distribution frame, we should first consider the factors are installed on the wall or rack, is it used for horizontal system, backbone network or centralized wiring?
Optical fiber distribution frame
Optical fiber distribution frame is generally installed in the distribution cabinet, for small installation may also be directly installed on the wall. If the distribution frame is used in a horizontal system, its density will be relatively high. Centralized fiber cabling technology can form backbone or horizontal channels in the building, which can then be generated using cables that are pulled, interconnected, or splicing from the work area to the central distributor. When used for horizontal systems or centralized wiring, the fiber may be a dual - or four-mode fiber cable. Backbone FIBERS can be MULTImode, SINGLE-mode, or HYBRID fibers, and these typically use connectors to complement the network hardware.
The number and size of optical fibers entering the distribution frame should be considered to ensure that enough holes of appropriate size are produced to accommodate the cable seal tube. With Small Package (SFF) connectors, a 1U distribution frame can accommodate up to 24 duplex connectors or 48 fiber bundles. So how to choose the right distribution frame? What do we need to think about?
The FIRST CONSIDERATION IS CABLE RETENTION: A certain amount of cable should be retained to ensure that a fiber-strength film is produced on the distribution frame chassis. This prevents the fiber from being ripped out of the distribution frame and prevents the cable from being subjected to excessive stress.
The second is its protection performance: the optical fiber distribution frame should provide sufficient protection for the connectors to prevent accidental contact.
Finally, its applicability: THE fiber distribution frame should be able TO ALLOW the removal OF EXISTING connectors and the addition of new connectors or fibers, and it must also be able to store and identify nonconnector fibers from horizontal or trunk cables.
