Abstract

A communication system is provided for improved data transmission. The system includes a first client (12) that includes an optical interface and at least a first optical network element (14) is coupled to the optical interface. A second optical network element (16) is coupled to the first optical network element (14). The first and second optical network elements each include a mechanism (32) for routing wavelengths under the control of the client. Also included are one or more data fibers (18) coupled to the optical interface and the first optical network element (14), and one or more control channels coupled (20) to the client (12) and the first optical network element. At least a first optical fiber (22) and a second optical fiber (24) are coupled to the first and second optical network elements. The first and second optical fibers and the first data fiber preferably support an optical path (21) between the first client and the second network element.
