US 2006/0133802 A1 · Method and system for shared optical regeneration

Abstract

An optical network includes an optical ring that is capable of transmitting, between two or more nodes, a plurality of working traffic streams that include traffic transmitted in one of a plurality of wavelengths. A node is capable of transmitting, in a first wavelength, a first protection traffic stream associated with a first working traffic stream, in response to an interruption of the first working traffic stream. A node is also capable of transmitting, in a second wavelength, a second protection traffic stream associated with a second working traffic stream, in response to an interruption of the second working traffic stream. The optical network also includes a regeneration element capable of selectively regenerating the first protection traffic stream. The regeneration element is also capable of tuning the regeneration element to receive traffic in the second wavelength and of selectively regenerating the second protection traffic stream.

Dependent claims

A method for providing optical communication, comprising:

transmitting a plurality of working traffic streams on an optical ring, each working traffic streams comprising traffic transmitted in one of a plurality of wavelengths of an optical signal;
in response to an interruption of a first working traffic stream, transmitting, in a first wavelength, a first protection traffic stream associated with the first working traffic stream;
selectively regenerating the first protection traffic stream at a regeneration element coupled to the optical ring, the regeneration element being tuned to receive the first wavelength;
in response to an interruption of a second working traffic stream, transmitting, in a second wavelength, a second protection traffic stream associated with a second working traffic stream;
tuning the regeneration element to receive the second wavelength;
and
selectively regenerating the second protection traffic streams at the regeneration element.
