HYBRID ELECTRICAL-OPTICAL DATA COMMUNICATIONS CABLE WITH WIRELINE CAPACITANCE COMPENSATION

摘要

A communications cable is disclosed. The cable includes a first circuit configured to receive electrical data signals from a data source via an input connector, and convert the electrical data signals into optical signals for transmission by way of one or more optical fibers. The cable includes a second circuit configured to convert the optical signals received via the one or more optical fibers back to electrical data signals for providing to a data sink via an output connector. The cable includes a third circuit for applying pre- and post-signal conditioning to bi-directional control data for transmission to and received from the data sink via wires. The cable includes a fourth circuit for applying pre- and post-signal conditioning to bi-directional control data for transmission to and received from the data source via wires. The pre- and post-signal conditioning compensate for capacitance and/or resistance effects on the signals introduced by the wires.
