Abstract:
1. An optical cable system, comprising: first switching circuitry configured to switch a first signal associated with a first electrical transmit signal; a first resistance network comprising at least one resistor coupled to the first switching circuitry and to a fixed voltage level, the first resistance network contributing to an impedance presented at a node associated with the first electrical transmit signal, the first switching circuitry switching the impedance in response to a first switching signal; first optical-to-electrical signal conversion circuitry configured to detect and convert a first optical receive signal into a first electrical receive signal, configured to provide the first electrical receive signal to the first mateable electrical connector, and configured to produce the first switching signal in response to detecting the optical receive signal; and first electrical-to-optical signal conversion circuitry having an input coupled to the first resistance network, the first electrical-to-optical signal conversion circuitry configured to convert the first electrical transmit signal into a first optical transmit signal.
