Patch cables and patch cords are flexible cables that are terminated at both ends with a plug and used to interconnect circuits. These male/male cables and cords are used with patch panels, groups of ports that connect lines between communications and electronic devices. Connections that are made manually with small patch cords are easier to wire than automatic switches. Patch panel ports accommodate specific types of connectors, including Bayonet Neil-Concelman (BNC), subscription channel (SC), straight tip (ST), registered jack (RJ), small computer systems interface (SCSI), and universal serial bus (USB). When selecting patch cables and patch cords, cable type is the most important specification to consider.
