Our series of patch cords offer a quick and accurate method of identifying the termination point of optical patch cords. Each end of OPTiLite patch cords offer a flashing light allowing technicians to visually trace individual patch cords from one end to another without pulling or affecting the patch cord. OPTiLite is supplied with special power sources easily attached to the patch cords. The LED light will blink every 2 seconds, stopping after 30 seconds.
