In telecommunication, a fiber distribution frame is a passive device which terminates cables, allowing arbitrary interconnections to be made. Distribution frames for specific types of signals, such as ADF - audio distribution frame, DDF - digital distribution frame, ODF or OFDF - optical fiber distribution frame and VDF - video distribution frame. Today we are have a toptic on ODF.

ODF is primarily is a fiber optic management unit which is used to organize the fiber optic cable connections, used to connect and schedule optical fibers and optical cables. It is applicable to fiber intersections between an optical transmission network and optical transmission devices as well as between optical cables in an access networks.

The ODFs are available in a range of configurations depending on applications

a.Pre-terminated ODFs with stub cables are pre-installed with connectors and cable for quick and easy installation. Units with pre-terminated cables offer advantages such as faster installation, resulting in shorter time to revenue as well as guaranteed quality and performance. Several cable options are available, such as POF cable, Ribbon cable, tight buffer cable, armored dielectric fiber optics cable, etc. ODFs with stub micro cables are especially suitable for high packing density applications such as the Ericsson Multifiber Management System (MMS).

b.Pre-terminated ODFs with micro cable on reel are delivered attached to a reel with longer lengths of outdoor rated micro cable, eliminating time consuming and costly splicing of cables in the central office. This is also a preferred option in combination with the Multifiber Management System.

c.ODFs for cable installation are intended for installation and termination of all kinds of fiber optic cables(of course include POF cable). The units are suitable for splicing pigtails or fiber ribbon fanouts as well as field-installable connectors. The ODFs are delivered empty, allowing the customer to order the pigtails/fanouts, adapters, splice protection sleeves and installation kit that best suit the specific application. The units can also be installed with pre-connectorized cable assemblies.

d.ODFs for air blown fiber are designed to handle termination of ducts for air blown fibers. They are typically used in FTTx applications when blowing fibers directly to a central office or other distribution point. The air blown technology enables incremental installation when needed.

According to different sizes, there are 1U 12 ports, 1U 24 ports, 2U 36 ports, 3U 48 ports, 4U 72 ports and 5U 96 ports ODFs. The optic distribution frame is usually used indoor and the ODF could be very big size frame or small size similar like the patch panel boxes. Install type has rack mount and floor mount options.

FiberStore provide the fiber optical distribution frames with 12 ports, 24 ports, 36 ports, 48 ports, 72 ports, 96 ports and 144 ports types. These optical distribution frames are made of cold-rolled steel sheets and it is with proper structure and neatly looking.
