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, the first connector comprising;

    a first controller configured to generate a first mode signal based on whether the first connector is connected to the data source or the data sink;

    a first modulator configured to modulate a first optical signal with a first data signal from the data source based on the first mode signal;

    a first demodulator configured to demodulate a second optical signal to produce a second data signal based on the first mode signal;

    a first switch circuit configured to;

    route the first data signal from the data source to the first modulator based on the first mode signal indicating that the first connector is connected to the data source; and

    route the second data signal from the first demodulator to the data sink based on the first mode signal indicating that the first connector is connected to the data sink;

    a second connector configured to mate with a corresponding connector of the data source or the data sink, the second connector comprising;

    a second controller configured to generate a second mode signal based on whether the second connector is connected to the data source or the data sink;

    a second modulator configured to modulate the second optical signal with the second data signal from the data source based on the second mode signal;

    a second demodulator configured to demodulate the first optical signal to produce the first data signal based on the second mode signal;

    a second switch circuit configured to;

    route the second data signal from the data source to the second modulator based on the second mode signal indicating that the second connector is connected to the data source; and

    route the first data signal from the second demodulator to the data sink based on the second mode signal indicating that the second connector is connected to the data sink; and

    a cable housing at least partially enclosing;

    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.
