Abstract
A method and system for high bit rate fiber-optic communications utilize a wavelength tunable transmitter controlled by a feedback signal from an error analyzer associated with a received optical data stream.
Claims23
Method for high bit rate fiber-optic communications over a span having at least one pair of single-mode transmission fibers, comprising:
- transmitting optical data streams at selected optical wavelengths through a first fiber of a pair of fibers;
- analyzing error data in received optical data streams associated with terminals coupled to the span;
- and
- propagating a control signal toward a transmitter through at least one of a second one of said pair of fibers and a management network, said control signal adapted to modify an optical wavelength transmission parameter in a manner tending to reduce said error data.

A system for high bit rate fiber-optic communications, comprising:
- a span having at least one pair of single-mode transmission fibers;
- a first terminal coupled to a first end of the span;
- and
- a second terminal coupled to a second end of the span;
- wherein each terminal comprises:
- a wavelength tunable transmitter;
- an optical receiver comprising an optical amplifier, a chromatic dispersion compensating module, and a photo-receiver;
- and
- an error analyzer associated with a received data stream, wherein the error analyzer provides a feedback signal controlling a wavelength of the wavelength tunable transmitter of the received optical data stream.
