a design module of analog computers intended to connect operating units, which perform various computations, with the logic elements according to the system of equations that has been assigned for solution.

A distinction is made between removable and fixed patchboards. Switching is ordinarily achieved by flexible (shielded) cords with single-pole plugs, which are placed in the openings of the removable patchboard and contact the flexible springs of the fixed part of the patchboard or are plugged into sockets mounted directly on the front panel of the operating units (in the case of a fixed patchboard). Modern analog computers are equipped with two types of removable patchboards, one for switching operating units and the other for switching elements of parallel logic. Removable patchboards make it possible to perform the labor-intensive preparatory operations of setting up the problem away from the computer, thus increasing its efficiency. In analog computers operating in hybrid computer systems, patchboards are replaced by systems for automatic switching of operating and logic elements using electronic switches and electronically controlled coefficients (according to a program from the digital computer).

The patch panels are suitable for the use of pre-terminated and factory-tested cable assemblies as well as for the classic mounting of installation cables and RJ45 connection modules.
ADC has introduced a new high-performance TrueNet CopperTen Patch Panel for 10-gigabit Ethernet transmission.
Attenuation can be attributed to a number of elements, including fiber distance, number of patch panel connections (typically 0.5dB of loss) and splices, dirty fiber connectors.
The cable management in the data closets included a methodical routing system which properly labels each cable from the desk to the Ortronics GigaMo+ patch panels. Each patch panel port was assigned a number that corresponds to the workstation outlet and the location in the building.

Knoxville, TN, July 04, 2012 --( VERICOM, a global manufacturer of cable and cabling solutions based in Knoxville, Tennessee, is using the month of July to offer VERICOM CAT5E Unshielded Patch Panels with back to back RJ-45 connectors, designed for use in a variety of technology, business and a host of networking applications, at a highly discounted rate to offer businesses the ability to continue to grow their market share in these critically important industries.
It reduces patch panels in the racks or cabinets, freeing up space there for active components.
According to the company, the connector will double the port count of hubs, switches, routers and adapter cards, using less than half the space as the standard RJ connector, and it will provide double the connections to telephones phone handsets, wall plates and patch panels. It is also designed for emerging 10 GB UTP applications.
Vertical patch panels are a more recent addition to the zero-U equipment offering.
