Overview Of DIN Rail Fiber Optic Patch Panel

By Lucia Weeks


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).

In turn, in a form to complete normalization can take the signal without interrupting transit. A forcing of output signal, however, the interrupt. In case of a module seminormalizzato instead, a rope is inserted into an input output will interrupt the transit of signal. For the benefit of matrix, there is the fact that each signal can be sent to any destination without any limit to amount of times it is used, while the patchbay is inevitably limited by the availability of multiple copies of a signal, in typically from a distributor but nonetheless present in a limited number of copies.

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.

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.

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 ).

It has many other advantages such as low signal loss, reduced size and weight, immunity to electromagnetic and radio frequency emissions and safety. As a result of studies focused on optical physics, a new method of use for light called laser beam was discovered.
