Optical distribution frame (Optical Distribution Frame) is used for the termination and distribution of the central office trunk optical cable in the optical fiber communication system, which can easily realize the connection, distribution and scheduling of optical fiber lines.
Main features of ODF:
●Full modular design, full frontal operation;
●Integrate welding and wiring to maximize high density;
●Can be installed on a 19-inch standard rack;
●Suitable for ribbon and non-ribbon cables;
Various adapters such as FC, SC, ST and LC can be installed by snap-fitting;
The adapter and the device are installed in a 30° snap-fit, which not only ensures the bending curvature radius of the jumper, but also avoids laser burns to the human eye, which is convenient for operation and perfect in protection;
●Both optical cables and pigtails have a storage space of more than 2m.
Features of Optical Fiber Distribution Frame
In recent years, in the actual work of optical communication construction, through the comparison of the use of several products, we believe that the selection of optical fiber distribution frame should focus on the following aspects.
(1) Core capacity
An optical fiber distribution frame should enable the optical cable with the maximum number of cores in the office to be completely put on the shelf. If possible, several optical cables with more interconnections can be put on a shelf to facilitate the deployment of optical paths. At the same time, the capacity of the distribution frame should correspond to the series of general optical cable cores, so that the waste of capacity of the optical fiber distribution frame due to improper matching can be reduced or avoided during use.
(2) Types of functions
As the terminal equipment of the optical cable line, the optical fiber distribution frame should have 4 basic functions.
①Fixing function After the optical cable enters the rack, the outer sheath and reinforcing core shall be mechanically fixed, the ground wire protection component shall be installed, the end protection shall be carried out, and the optical fibers shall be grouped and protected.
②Acceptance function After the optical fiber drawn out of the optical cable is spliced with the pigtail cable, the redundant optical fiber is coiled and stored, and the spliced joint is protected.
③Adjustment function Plug the connector attached on the pigtail cable to the adapter, and realize the optical path docking with the optical connector on the other side of the adapter. Adapters and connectors should be able to be plugged and unplugged flexibly; optical paths can be freely deployed and tested.
④Storage function Provide storage for various cross-connected optical cables between racks, so that they can be placed regularly and neatly. There should be appropriate space and method in the optical fiber distribution frame, so that this part of the optical connecting line is clearly routed, easy to adjust, and can meet the requirements of the minimum bending radius.
With the development of optical fiber network, the existing functions of optical fiber distribution frame can no longer meet many new requirements. Some manufacturers add some optical fiber network components such as optical splitters, wavelength division multiplexers and optical switches directly to the optical fiber distribution frame. In this way, even if these components are easily applied to the network, they add functionality and flexibility to the optical fiber distribution frame.
Optical fiber distribution frame is mainly divided into: 12 optical fiber distribution frame, 24 optical fiber distribution frame, 48 optical fiber distribution frame, 72 optical fiber distribution frame, 96 optical fiber distribution frame, 144 optical fiber distribution frame.
Fiber Reel in ODF
According to the different optical cables and interface methods, the optional optical fiber couplers include FC, ST, SC, LC, etc., and the optical cables include indoor and outdoor single-mode, multi-mode, and 10 Gigabit OM3 optical cables.
The bare fiber protection tube is mainly used for the protection of the bare fiber segment in the distribution frame, the fiber optic splicing box and the core after the bare fiber is stripped, which can effectively protect the bare fiber optical fiber from damage. Good protection, not easy to break.
Main shapes: oval, round, rectangular; Operating temperature: -55℃~100℃, maximum operating temperature 120℃; Standard color: transparent Other specifications can be customized according to customer requirements.
