Hello,
Today, I would like to share with you the ODF.
1- Introduction
The optical distribution frame (Optical Distribution Frame) is used for the termination and distribution of the ODF frame of the central office backbone optical cable in the optical fiber communication system, which can easily realize the connection, distribution and dispatch of optical fiber lines.
Main features of ODF:
Fully modular design, full frontal operation
Integrate welding and wiring together, maximizing high density
Can be installed on a 19-inch standard rack
Suitable for ribbon and non-ribbon optical cables
Various adapters such as FC, SC, ST and LC can be installed by card
The adapter and the device are installed in a 30° snap-on type, which not only ensures the curvature radius of the jumper, but also avoids laser burns to human eyes. Easy operation and perfect protection
Optical cables and pigtails both have a storage space of more than 2m
Common ODFs are as follows:
Figure 1 12-core optical fiber distribution frame
Figure 2 24-core optical fiber distribution frame
Figure 3 72-core optical fiber distribution frame
Figure 4 Optical fiber distribution cabinet
2- ODF basic functions
1) Optical cable fixing and protection function
It shall have optical cable introduction, fixing and protection devices. The device introduces and fixes the optical cable on the rack to protect the optical cable and the fiber core in the cable from damage. The metal part of the optical cable is insulated from the metal frame, and the metal sheath and reinforcing core of the fixed optical cable should be reliably connected to the high-voltage protective grounding device.
2) Optical fiber termination function
It shall have optical fiber termination device. The device is convenient for splicing operation, construction, installation and maintenance of optical cable core and pigtail. It can fix and protect the joint parts straight and without displacement, avoid the influence of external force, and ensure that the coiled optical cable core and pigtail are not damaged.
3) Thread adjustment function
Through the optical fiber jumper connector plug, it can quickly and conveniently schedule the core number in the optical cable and change the path sequence of the optical transmission system.
4) Protection function of optical cable core and pigtail
After the optical cable is stripped, there is a protection device for the core, and a termination device for the introduction of the optical fiber after being fixed.
5) Capacity
The capacity of each rack and unit capacity (determined by the number of adapters) shall be specified in the product enterprise standard, and the optical fiber termination device, optical fiber storage device, and optical fiber connection distribution device shall be capable of being configured as a complete set within the full capacity range.
6) Identification record function
The rack and unit should have a complete identification and recording device to easily identify the core number or transmission path sequence, and the recording device should be easy to modify and replace.
7) Optical fiber storage function
There should be enough space in the rack and unit to store the remaining optical fiber.
