Abstract
A connector/cable identification system comprises a plug having an extension and a female housing having at least two pairs of optical emitter/sensors. Each emitter/sensor pair detects whether the extension is therebetween. Because different extensions have different lengths or aperture configurations, the type of connector (and thus associated cable) can be determined. Voltage isolation between the cable (i.e., a common carrier transmission line) and the apparatus receiving the cable (i.e., a personal computer) is maintained by physically separating the transmission circuitry from the identification circuitry.
