1. A communications cable, comprising:
an input connector configured to:
connect to a data source;
receive a first set of electrical data signals from the data source;
receive a second set of electrical data signals from the data source; and
provide a third set of electrical data signals from a data sink to the data source;
an output connector configured to:
connect to the data sink;
provide the first set of electrical data signals to the data sink;
provide the second set of electrical data signals to the data sink; and
receive the third set of electrical data signals from the data sink;
a set of one or more optical fibers coupled to the input and output connectors;
a set of one or more electrical wires coupled to the input and output connectors;
a first circuit configured to convert the first set of electrical data signals into an optical signal for transmission to the output connector by way of the set of one or more optical fibers;
a second circuit configured to convert the optical signal received by way of the set of one or more optical fibers back to the first set of electrical data signals;
a third circuit configured to apply a first signal conditioning on the second set of electrical data signals received by way of the set of one or more wires, wherein the first signal conditioning comprises amplifying, buffering, and equalizing the second set of electrical data signals; and
a fourth circuit configured to apply a second signal conditioning on the third set of electrical data signals received by way of the set of one or more wires, wherein the second signal conditioning amplifying, buffering, and equalizing the third set of electrical data signals.
