Fiber Optic Distribution Frames are available in both single and double rack versions, and can be integrated into central office, optic connectivity nodes, optic sub-distributors, and fiber outdoor cabinets.
Each of these product has been adapted to serve as indoor distribution rack for operators, in accordance with the regulations applied today to FTTH network material, and they manage a high density of optic fibers and subscriber connections, ranging from 900 to 1,100 subscribers.
Designed to house 19-inch modules for connecting, splicing, and storing of optic fibers, they are also compatible with all the equipment required to build FTTH networks.
Both versions include a fully functional refrigeration area, comprised of cable holders in the form of vertical cylinders designed to facilitate shipping within the ODF.
In addition, they can be fixed to a wall or directly to the floor, being also possible to place them back to back or sideways.

3. Function of optic distribution frame
Welink expands the range of uses of the modular patch panel for fiber optic networks with a new product: the Optic Distribution Frame (ODF), aimed at main installations of network operators, such as centers of concentration and central offices.
With the ODF it is possible to connect a large number of optic fibers and distribute them in a small space, for which it can be equipped with basic components of the patch panels. As a result of the constant expansion of FTTx architectures for ultra-broadband networks, network operators must host an increasing number of fiber optics in their facilities. With the optic switchboard and patch panels, Welink helps operators expand their networks faster, easier and more reliably.
The ODF rack can be configured with splice modules, patch modules, and splitter modules, which are mounted using a quick, tool-free installation technique. An ODF rack can manage up to 2034 fibers. The system guarantees a maximum bend radius of 40mm, which is a deciding factor for reliable, stress-free fiber management and quality criteria for future high-capacity and xWDM applications. Made of aluminum profiles, the optic ODF has basic dimensions of 300 x 300, 600 x 300 or 900 x 300 mm and 2.2 m high. Welink has removed front struts, giving technicians and maintenance personnel greater freedom of movement. The splice patch panel also serves as an integrated work table. The splice module is equipped with 48 SC adapters or 24 optic splice trays, each holding 6 or 24 fibers. The distributor rack is therefore compatible with the 24-fiber loose tube cable. The optic splice trays are instantly inserted into the module and passed from one to the other as if they were cards in a filing cabinet. Each tray admits assignments by locality, by a locality or by specific subscribers. A space for interchangeable labels and the use of numbers and color codes facilitate the administration of large quantities of fibers. The patch module can be used for distribution applications or to connect finished cables. Up to twelve inserts per module are possible, each with twelve LC duplex, E2000 Compact connectors. It is compatible with mini-breakouts, multipatch cables and wire harnesses, as well as pre-terminated cables. Welink also offers a combined ODF module that brings together the splice and patch sections in one housing, also available as a pre-tested and factory-tested unit. The expansion of broadband networks is causing an exponential growth in the volume of installed optic fibers. Network operators need new solutions to be able to manage these quantities easily and reliably. For this reason, welink created the individualized management of the fiber optic circuit, a modular tray system suitable for all parts of the network, from the main distributor to the connection point in the building. The optic rack allows a common method to be adopted for managing fibers and subscriber connections. It supports current FTTx market strategies such as point-to-point (P2P) or point-to-multipoint (P2MP) and open access, as well as future high-capacity and xWDM applications for ultra-wideband networks. In this way, the FTTx infrastructure can be quickly and flexibly expanded or adapted to the specific needs of the network provider. Its wide radius of curvature, 40 mm, is one of the most outstanding characteristics of our products, since the absence of tension minimizes losses due to attenuation and facilitates handling during installation.
