Bidirectional data communications cable
First Claim
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.

Abstract
A bidirectional data communications cable is disclosed. The cable includes first connector, second connector, and cable housing coupled to the first and second connectors. The first connector includes a controller configured to determine whether the first connector is connected to a data source or data sink. If connected to a data source, the controller configures a switch circuit to route a data signal from the data source to an optical modulator for modulating an optical signal for transmission from the first to the second connector via an optical fiber. If connected to a data sink, the controller configures the switch circuit to route a data signal from an optical demodulator to the data sink, the optical demodulator receiving an optical signal modulated with the data signal from the second connector via an optical fiber. The second connector is configured similar to the first connector. The cable housing encloses the optical fibers.
