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.
This type patchbays is also used for digital audio interface with AES / EBU, in variant AES3id; the connector used on back of a patchbay is the BNC type, while the strings have a special coaxial connector. Analog audio signals on a balanced pair or digital AES / EBU. In this case, terminals of disconnector are usually to be welded directly; the strings are stereo jack or fittings multipolar different depending on manufacturer.
Optical fiber is a transmission medium, usually employed in data networks, consisting of a very thin thread of a transparent material, glass or plastics, through which light pulses representing the data to be transmitted are sent. The light beam is completely confined and propagates inside the fiber at an angle of reflection above the critical angle of total reflection, according to Snell's law. The light source can be laser or LED.
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.
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.
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.
