The Classification of Fiber Termination Box I

Date:30-11-2016

Fiber termination box (FTB), known as optical termination box (OTB) as well, is a compact fiber management product of small size. It is widely adopted in FTTx cabling for both fiber cabling and cable management. In some circumstances, fiber termination box can be regarded as the mini size of fiber optic patch panel and optical distribution frame (ODF).

Currently, the market embraces a great amount of fiber optic termination boxes and other devices for cable management. And the names and model numbers of these fiber termination boxes vary from the design and idea of different manufacturers. Hence, to identify the detailed classification of fiber termination box could be a hard task.

Roughly, fiber termination box can be categorized as fiber optic patch panel and fiber terminal box according to the size and applications. Judging by the appearance, fiber patch panel is of gibber size whereas fiber terminal box is smaller.

Fiber patch panels are of wall mounted type or mounted type usually with 19 inch size. Generally, there is a tray inside the fiber box that helps to hold and protect the fiber links. Various different kinds of fiber optic adapters can be pre-installed in fiber patch panels as the interface, via which the fiber box could connect with the external devices.

Besides fiber patch panels, one can also count on fiber terminal boxes for fiber distribution and organization. While typical fiber terminal boxes are with 12 ports or 24 ports, 8 ports, 36 ports, 48 ports and 96 ports fiber are available in the markets now. They are often installed with FC or ST adapters on the panel, either on the wall or put in horizontal line.

What’s more, according to the design, fiber termination box can be further divided into wall mount type and rack mount type.

The wall mount fiber termination boxes are designed for either pre-connectorized cables, field installation of connectors, or field splicing of pigtails. They offer an ideal solution for building entrance terminals, telecommunication closets, main cross-connects, computer rooms and other controlled environments.

The rack mount slide-out type fiber termination box is usually for fiber splicing, distribution, termination, patching, storage and management in one unit. They support both cross-connect and interconnect architecture, and provide interfaces between outside plant cables and transmission equipment.
