The wiring of patchbay is designed so as to group together in a logical manner, by the type and use, all wiring connected, so that it is easy to test them, monitor them or interconnect, with a greater flexibility of use with respect to a fixed installation. Disconnecting electric utilities, for connections to a plant's theatrical stage lights (DIN Rail Fiber Optic Patch Panel).

While in functionally similar cross rails or switching networks, the sources and destinations are created as a matrix and thus arbitrarily can be switched together (n: m), can be associated with patchbays normally only ever a source to a destination (1: 1). The rear is not accessible usually in normal operating on the plug-fields vary - depending on the desired signal quality and ease of remapping are (single or multi-core) connectors, spring terminals or solder tags used.

The use of patchbay is rather large in entertainment industry and more particularly in television, and is also widely used in computer networks. Disconnection video signals of mobile direction. Note on left a series of panels not normalized with fittings inserted and, in blue, a rope. Each type wiring is suitable in principle to use of patchbay. Depending on type signal, changes the type cable that carries it and the type connector used. Common examples of patchbay are: Video signals over coaxial cable 75. There are different specifications depending on type video.

In building technology patchbays (there usually referred to as patchbay) used to interconnect all distributed over a larger area terminal connections to a central point can. To facilitate handling and to increase the clarity, patchbays, certain signaling pathways have pre-configured internally connected without plugging the cable.

Serial connections for control interfaces, with solder terminals and cords that often use multi-core cables with RJ45 connectors. Various types of parallel connections for general purposes. Connections are often solder or insulation, and the strings multipolar. The patchbay more sophisticated have a modular structure: on each panel are mounted on rear side of modules that receive two cable sections and on FRONT have two overlapping holes corresponding to two sections.

The fibers are widely used in telecommunications, allowing large amount of data sent over a long distance, with similar radio and superior to those of conventional cable speeds. Are the transmission medium par excellence, to be immune to electromagnetic interference, and are also used for local networks where you need to take advantage of optical fiber over other transmission media.

Naturally it is not possible to cross between them two types of different signals. As a general rule, although it is not a fixed rule, the top line of panel receives incoming connections to patchbay (and then the outputs of machines), while the lower sends outgoing connections (and therefore to inputs machines ).

There is a firm connection between all bushings, which is not interrupted by cable plugging. This makes it possible to derive from the stereo sum of mixer, the signals for a recording device. With an open configuration exists between the two jacks on no electrical contact. The patchbay or disconnector is a system that interfaces between them different sections of a wiring. Typically consists of a series of perforated panels on the back of which are radiused sections wiring. Between a hole and the other, that is, by two sections, it is possible to realize a connection via a length of cable, also called a patch cord or rope.
