A patchbay is, in many areas of wired data transmission (eg audio, telephone and video technology or computer networks) a technical device to simplify wiring, where usually several devices are connected, their compounds comfortable using short patch cable may be prepared and changed with attached to front bushings (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 common practice, in any case, the patchbay and matrix coexist, generally by cutting all the inputs and outputs of matrix. This allows to realize simple by-pass in case of emergency. There is also the advantage of not having to put in array signals used rarely, if necessary, that are still available on the patchbay.
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 modular structure allows to compose patchbay capable of routing connections of different types of signals on same panel, saving space if the number of signals is limited. Typically, in a panel on top rack unit can accommodate 24/26 modules. You can make a panel with, for example, video connections 8, 10 and 6 serial audio.
The great innovation introduced in our time is to be able to "tame" the light, so that it is possible to spread within a man laying cable. The use of guided light, so it does not expand in all directions, but in a very concrete and predefined has been achieved through the optical fiber, we can think like a glass pipe -glass fibers ultra delgada- protected by a insulating material serves to transport the light signal from one point to another.
Depending on use, there are three types of disconnectors, whose normalization of signals may be absent or complete, or it may be disconnectors. The normalization indicates the way in which the elements of single module are wired internally. In a form without normalization, a rope is required for the transit of signal (or a dedicated short cable to U), while in a normalized form the input signal to patch panel is always connected to corresponding output.
