초록 ▼

A fiber optic data transmission system includes an optical fiber and a data transmitter having a first laser having a first wavelength, a first phase modulator for phase modulating light from the first laser as a function of a first data input stream so as to create a first phase-modulated output data stream, a second laser having a second wavelength different from the first wavelength, and a second phase modulator for phase modulating light from the second laser as a function of a second data input stream so as to create a second phase-modulated output data stream. The transmitter also includes a combiner combining the first and second output data streams into a phase-modulated optical signal for transmission over the optical fiber.

대표청구항 ▼

1. A method for transmitting data over optical fiber comprising the steps of: transmitting light at a first wavelength via a first laser;phase modulating light at the first wavelength at a data transmitter as a function of a first electronic data input stream so as to create a first output data stream, a first binary bit being represented by a first phase and a second binary bit being represented by a second phase different from the first phase;transmitting light at a second wavelength different from the first wavelength;phase modulating light at the second wavelength at the data transmitter as a function of a second electronic data input stream so as to create a second output data stream;combining the first and second output data streams; andlowering a power output of the first laser via a controller as a function of a bit error rate;wherein the phase modulating of the first wavelength is a function of outputs of delayed-feedback exclusive-or gates. 2. The method as recited in claim 1 wherein all of the light from the first laser is phase-modulated. 3. The method as recited in claim 1 further including receiving the phase-modulated combined output data streams in a receiver, and splitting the combined output data stream into a first path at the first wavelength and the second path at the second wavelength. 4. The method as recited in claim 3 further comprising passing each of the first and second paths through an interferometer. 5. The method as recited in claim 1further including monitoring the power to detect an intrusion. 6. The method as recited in claim 1 further comprising maintaining a bit error rate while performing the lowering of the power output.
