Under the agreement, C-cation Inc. will extend a patent license to Comcast for its passive hybrid fiber-coaxial architecture technology. Financial terms of the agreement were not released, nor is Comcast releasing any information on how it plans to use the technology in its existing cable-plant architecture.

A private company based in Rye, N.Y., C-cation filed suit against the former AT&T Broadband last July, charging that the MSO’s "LightWire" passive-optical-transmission technology had infringed on its patents.

The LightWire architecture, which was tested in Salt Lake City in 1999, created mini-nodes to push fiber closer to customers, boosting bandwidth for voice-, video- and data-service delivery.

"We are excited that we now have an ongoing business relationship with Comcast," C-cation president Alexander Cheng said in a release. "We look forward to deploying our other patented technological solutions to the cable industry."

C-cation is also working on a server-software communication-control module to oversee product offerings, Cheng said.
