Keeping pace with ever-increasing mobile data demand is simply impossible without a fundamental change to network architecture. This successful proof-of-concept shows that our innovation in G.metro technology is the answer.
The demonstration revealed how this innovative new architecture significantly increases fiber capacity in access systems. ADVA Optical Networking’s prototype technology, which is defined by the ITU-T G.metro standard, directly distributes DWDM wavelengths to remote radio units, base stations, desktops or end users. This enables up to 40 DWDM wavelength channels with a grid of 100GHz. Each channel is able to transmit data at 10Gbit/s over a 20km fiber distance without optical amplification. With a centralized wavelength locker at the head-end, cost and complexity at the tail-end are significantly reduced. This enhanced efficiency will be crucial for converged metro-access and for 5G networks in the near future. The prototype also proved to be fully compatible with current commercial wireless technology, paving the way for imminent real-world deployment.
“Today’s service providers are facing an unprecedented challenge. Keeping pace with ever-increasing mobile data demand is simply impossible without a fundamental change to network architecture,” commented Michael Eiselt, director, advanced technology, ADVA Optical Networking. “This successful proof-of-concept shows that our innovation in G.metro technology is the answer. After five years of continuous development, we’ve demonstrated the feasibility and reliability of the autonomous wavelength tuning concept. We’ve shown how it works in a live network to significantly reduce the overall cost of data transport. Now that our prototype has been trialed successfully with zero errors, G.metro technology has moved a big step closer to real-world deployment.”
