In a proof-of-concept trial , Verizon and Calix tuned up speeds of 34 Gbps through the use of bonded NG-PON2. Last year Verizon announced it was moving directly from GPON to NG-PON2 in order to better serve small and mid-size businesses with low latency, fiber-based speeds.
“We know how important connectivity is to small and mid-size businesses,” said T.J. Fox, senior vice president and president of Verizon Business Markets, in a statement. “These advances will deliver the promise of the cloud for our customers and bring them technology at parity to what previously was only in reach for large enterprises.”
Business and residential customers need to have broadband services that are as reliable as possible because they use them for applications and services such as home security, or to telecommute from home offices using HD video. Verizon is also going to NG-PON2 to combat the 1-Gig broadband offerings from various cable operators.
The trial, which was conducted in the Verizon Innovation Center in Waltham, Massachusetts, used Calix’s Axos system to bond four wavelength channels together by using software at the optical network terminal (ONT). By bonding the wavelengths, NG-PON2 is able to achieve faster speeds than what each individual wavelength is capable of reaching.
Leveraging compliant NG-PON2 optics, the AXOS Intelligent Edge system consolidates subscriber management, aggregation, and optical line terminal (OLT) functions into a single point in the network that’s closer to the subscriber.

NG-PON2 has four 10 Gigabit wavelengths that increase reliability of the service. If one PON card goes down, the other wavelengths are able to continue providing service.
The second key element of NG-PON2 is the tunable optics that enable operators to assign different subscriber types to different wavelengths. Using dynamic load balancing, a service provider could move a data hog to a separate wavelength via a provisioning command.
Using NG-PON2 as its universal access platform, Verizon will be able go beyond a 10-Gig wavelength to 20-Gig, 30-G and 40-Gig down the road.
Last year, Verizon and Calix successfully trialed NG-PON2 on the OLT (Optical Line Terminal) while Verizon conducted an NG-PON2 test in Tampa, Florida.
