Next-Gen Fiber Project Enters Field Trials

  • Tellabs
  • WDM-PON
ESPOO, FINLAND - The next generation of fiber optic networks is fast approaching. Verizon is trying out 10GPON, ADVA is experimenting with WDM-PON, and now the European Union-funded SARDANA project (short for Scalable Advanced Ring-based passive Dense Access Network Architecture), has entered field trials with France Telecom. If you can get to Milan, Italy, in February, you'll be able to see a demo of this new technology, a ring-based solution that merges metro and access networks.

Higher Capacity, Extended Reach
Using wave-division multiplexing (WDM), the new solution transmits signals over 32 wavelengths on each fiber, with 10 Gbps downstream and 2.5 Gbps upstream on each wavelength. SARDANA also extends the reach of the fiber connection up to 60 miles. As a result, about 1,000 homes can be served from a single optical line terminal (OLT) port - 15 to 30 times more homes than are served with today's technology.

"The SARDANA project shakes up PON technology, and it brings the potential for a new suite of high-quality services to our customers," says Dr. Philippe Chanclou, France Telecom. "We are very excited to start the field trials in Lannion (Brittany, France) close to our Orange Labs facilities, to demonstrate both the urban and rural scenarios of SARDANA." SARDANA uses technology from electronics vendor Tellabs.
