Xtera Communications Inc. and the University of Michigan have been granted U.S. patent no. 6,239,902 on Xtera's development of long-haul transport systems employing Lumped or Distributed Raman amplification on most types of NZ-DSF fibers.

Distributed Raman, which uses the transmission line fiber as the gain medium, is used by carriers to achieve greater transmission distances in long haul and ultra-long haul networks, reducing the need for expensive regeneration and enabling lower network costs.

Xtera has commercialized this patented technology in its Nu-Wave DWDM system, combining Lumped Raman and Distributed Raman Amplification. The Nu-Wave simplifies network design and planning while providing carriers with more scalable optical network solutions.

The company has a broad portfolio of patents in Raman amplification. It fully endorses the authorized use of its patented technologies and offers licensing arrangements that will allow this technology to be used extensively in telecommunications networks.
