Xtera Communications Inc. today announced that United States Patent No. 6,239,902 has been jointly awarded to Xtera Communications and the University of Michigan.
The patent illustrates Xtera's precedence in the development of long-haul transport systems employing lumped or Distributed Raman Amplification on most types of NZ-DSF fibers, assert company representatives. Jointly awarded to Xtera and the University of Michigan, Xtera holds exclusive rights in this patent.
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 uses this patented technology in its Nu-Wave DWDM system, which combines Lumped Raman and Distributed Raman Amplification to achieve superior transmission distances and greater capacity at drastically lower costs.
Xtera fully endorses the authorized use of its patented technologies and will, in most cases, offer licensing arrangements that will allow this technology to be used extensively in telecommunications networks.
