ODF Rack-mounted Fiber Distribution Frame

2024-03-08

Latest company news about ODF Rack-mounted Fiber Distribution Frame

Fiber distribution frame is an essential accessory in optical transmission systems. It is mainly used for fiber fusion splicing at the end of optical cables, installation of optical connectors, optical path adjustment, storage of excess pigtails, and protection of optical cables. It plays a crucial role in ensuring the secure operation and flexible utilization of optical communication networks.

 

 

 
Characteristics of Fiber Distribution Frames
 
 

In recent years, in the practical work of optical communication construction, through the comparison of several products, we believe that the selection of fiber distribution frames should focus on the following aspects.

1)Fiber Core Capacity
A fiber distribution frame should be able to accommodate the maximum number of cores of optical cables within a facility. Whenever possible, multiple cables that are interconnected should be housed in the same frame to facilitate optical path deployment. Additionally, the capacity of the distribution frame should correspond to the series of commonly used fiber core counts. This helps reduce or avoid wastage of capacity in the distribution frame due to improper matching during usage.

2) Functional Types

As a terminal equipment for optical cable lines, a fiber distribution frame should have four basic functions:

Fixation Function: After optical cables enter the frame, their outer sheaths and strength members should be mechanically secured, grounding protection components should be installed, end protection treatment should be performed, and fibers should be grouped and protected.

Termination Function: After fusion splicing the fibers led out from the cable with pigtail fibers, any excess fibers should be coiled and stored, and the spliced joints should be protected.

Deployment Function: Connectors on the pigtail cables should be plugged into adapters, and the optical connectors on the other side of the adapters should be connected to achieve optical path alignment. Adapters and connectors should allow for flexible insertion and removal, and the optical paths should be freely deployable and testable.

Storage Function: Provide storage for optical patch cords between racks, allowing them to be neatly arranged. The fiber distribution frame should have appropriate space and methods for clear routing of these optical patch cords, easy adjustment, and compliance with the minimum bend radius requirements.

With the development of fiber optic networks, the existing functions of fiber distribution frames cannot meet many new requirements. Some manufacturers are integrating additional fiber optic network components such as splitters, wavelength division multiplexers, and optical switches directly onto fiber distribution frames. This approach not only facilitates the application of these components into the network but also adds functionality and flexibility to the fiber distribution frame.


Fiber distribution frames are mainly categorized into: 12-port fiber distribution frames, 24-port fiber distribution frames, 48-port fiber distribution frames, 72-port fiber distribution frames, 96-port fiber distribution frames, and 144-port fiber distribution frames.
