1. A bidirectional data communications cable, comprising:
a first connector configured to mate with a corresponding connector of a data source or a data sink;
a first modulator configured to modulate a first optical signal with a first data signal if the first connector is mated with the corresponding connector of the data source;
a first demodulator configured to demodulate a second optical signal to produce a second data signal if the first connector is mated with the corresponding connector of the data sink;
a first switch circuit configured to:
route the first data signal from the data source to the first modulator if the first connector mated with the corresponding connector of the data source; and
route the second data signal from the first demodulator to the data sink if the first connector is connected to the corresponding connector of the data sink;
a second connector configured to mate with a corresponding connector of the data source or the data sink;
a second modulator configured to modulate the second optical signal with the second data signal if the second connector is mated with the corresponding connector of the data source;
a second demodulator configured to demodulate the first optical signal to produce the first data signal if the second connector is mated with the corresponding connector of the data sink;
a second switch circuit configured to:
route the second data signal from the data source to the second modulator if the second connector is mated with the corresponding connector of the data source; and
route the first data signal from the second demodulator to the data sink if the second connector is mated with the corresponding connector of the data sink; and
a first set of one or more optical fibers for transmitting the first modulated optical signal from the first connector to the second connector; and
a second set of one or more optical fibers for transmitting the second modulated optical signal from the second connector to the first connector.
