What is ODF Optical Distribution Frame?

1. What is ODF Optical Distribution Frame?
ODF is Optical Distribution Frame. The optical fiber distribution frame belongs to the optical fiber distribution equipment used in the optical fiber communication room. It is mainly used for the termination and distribution of the local trunk optical cable in the optical fiber system.

2. Types of ODF Optical Distribution Frame

• ODF optical distribution frame by structures
  According to different structures, ODF optical distribution frames can be divided into wall-mounted and rack-mounted. The wall-mounted ODF can be directly fixed on the wall. It is generally a box-shaped structure, suitable for places with a small number of optical cables and optical fiber cores. The rack-mounted ODF can be directly installed in the standard cabinet and is suitable for large-scale optical fiber networks.
  There are two types of rack-mounted ODF patch panels, one is a patch panel with a fixed configuration, and the optical fiber coupler is directly fixed on the chassis; the other is a modular design. Users can select corresponding modules according to the number and specifications of optical cables, which is convenient for network adjustment and expansion.
• ODF by distribution frame core number

3. Features of ODF Optical Distribution Frame

• Optical fiber distribution frame (ODF) and its optical fiber distribution box (unit box) adopt 19″ international standard installation interface;
• Fully enclosed cabinet structure, good dust resistance, physical protection of optical cable ends, and wiring to avoid accidental damage.
• The frame body is made of high-quality cold-rolled steel plate, and the large column is welded as a whole, with high strength and good rigidity; the surface coating adopts electrostatic spraying technology, which is corrosion-resistant.
• The frame body design adopts a modular structure, which can be flexibly configured according to different requirements to realize the assembly and installation, and the capacity expansion is convenient;
• The optical cable can be introduced into the rack (or optical fiber distribution box) through the cable entry hole at the top or bottom of the rack for fixing, grounding and protection. The fixed metal part of the optical cable is connected to the high-voltage protective grounding device and insulated from the frame.

4. The functions of ODF Optical Distribution Frame

The ODF fiber optic distribution frame is an optical fiber distribution equipment specially designed for the optical fiber communication room. It has the functions of optical cable fixing and protection. It can be assembled into an optical fiber distribution frame alone, or can be installed in a cabinet/rack together with the digital distribution unit and the audio distribution unit to form an integrated distribution frame.

The main functional requirements of ODF fiber optic distribution frame are as follows:

• Optical cable fixing and protection function. There should be optical cable entry, 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 fixed metal sheath and reinforcing core of the optical cable should be reliably connected to the high-voltage protective grounding device.
• Optical fiber termination function. There shall be a fiber optic termination device. The device is convenient for the operation, construction, installation and maintenance of optical fiber core and pigtail splicing. It can fix and protect the joint part to be straight without displacement, avoid the influence of external force, and ensure that the coiled optical fiber core and pigtail are not damaged.
• Patch cord function. Through the optical fiber jumper connector plug, the fiber core serial number in the optical cable can be quickly and conveniently scheduled and the route sequence of the optical transmission system can be changed. The connector attached to the pigtail cable is plugged into the adapter, and the optical path is docked 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.
• The protection function of optical fiber core and pigtail. After the optical cable is opened and stripped, the fiber core has a protection device, and after fixing, the introduced optical fiber has a termination device.
• Storage function. It provides 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 the wiring of this part of the optical connection line is clear, easy to adjust, and can meet the requirements of the minimum bending radius.
• Identification record function. The racks and units should have complete identification and recording devices for easy identification of the fiber core serial number or transmission path sequence, and the recording devices should be easy to modify and replace.

5. The value of ODF optical distribution frame in the integrated wiring system

In the integrated wiring system, the distribution frame is suitable for horizontal wiring or device termination between devices, as well as the interconnection and termination of centralized points. The sturdy and easy-to-install design reduces installation and operation costs, and the large front label space facilitates port identification and management, and meets the 19″ rack installation standard. At present, ODF has been commercialized in many regions, and it is suitable for operators. It brings multiple values:

• Large capacity, high density, reduce the number of cabinets, save the space of the computer room, and increase the utilization rate of the computer room;
• Real-time monitoring of ports can improve the efficiency of fault location and reduce labor costs;
• Intelligent construction ensures accurate routing information, reduces sunk ports, and saves operation and maintenance costs;
• EID electronic identification reduces the hidden danger of information leakage caused by paper labels;
• The intelligent intermediate distribution cabinet and the intelligent optical fiber distribution frame can realize the intelligence of the computer room, which is easy to deploy and maintain.

6. The difference between ODF distribution frame and optical fiber distribution frame.

• Reference is different.
  ODF distribution frame. It is an important part of the information room and has the functions of optical cable fixed protection, optical cable connection and line adjustment.
  Optical fiber distribution frame: Optical fiber distribution equipment specially designed for optical fiber communication room.
• Scope of application.
  ODF distribution frame. It is an indispensable part in the information room, with functions such as optical cable fixed protection, optical cable connection, and line adjustment.
  Optical fiber distribution frame: It is suitable for small and medium-sized distribution systems such as fiber-to-cell, fiber-to-building, remote modules, and wireless base stations.
• The usage is different.
  ODF distribution frame. It can protect the core wire and pigtail of the optical cable. The device is flexible in configuration, simple in installation and use, and easy to maintain and manage. It is essential equipment for optical fiber communication and wired network terminals or relay points to realize optical fiber arrangement and fiber jumper cable fusion.
  Optical fiber distribution frame: It is used for the termination and wiring of the main optical cable in the optical fiber communication system, which can easily realize the connection, wiring and scheduling of the optical fiber line. With the continuous improvement of network integration, an optical-digital hybrid distribution frame that integrates ODF, DDF and power distribution units has emerged.

7. Summary
ODF optical distribution frame is the main equipment in the current communication distribution equipment. ODF can protect the optical fiber core and pigtail, can be assembled into an optical fiber distribution frame alone, or can be installed in a cabinet/rack together with the digital distribution unit and the audio distribution unit to form an integrated distribution frame. The device is flexible in configuration, simple in installation and use, easy to maintain, and easy to manage.
