Nokia and KPN have demonstrated 20Gb/s broadband speeds in a field trial with the Caresse animal hospital in Rotterdam, The Netherlands. High-speed connectivity is increasingly important in veterinary medicine where high-resolution images need to be accessed in the cloud. Symmetrical speeds of 20Gb/s would be capable of uploading (or downloading) almost 100 scans of 30MB each in one second.

KPN used Nokia’s state-of-the-art 25G PON technology in the field trial using its existing fibre network. With Nokia’s Quillon chip, 25G PON can work alongside GPON and XGS-PON on the same fiber, and powered by the same access node.

“When we designed our Quillion chipset, a key requirement was to be able to support multiple PON technologies on the same fiber, giving operators the flexibility to offer different service levels dependent on the customers’ needs,” said Sandy Motley, President of Nokia Fixed Networks.

Nokia’s 25G PON solution utilizes the world’s first implementation of 25G PON technology and includes Lightspan and ISAM access nodes, Quillion based Multi-PON line cards and fiber modems.

Dependent on the optics chosen, 25G PON supports symmetrical bitrates (25Gb/s in downstream and 25G in upstream) and asymmetrical bitrates (25/10).

Usually located in telecom central offices, Nokia’s high-capacity access nodes are deployed for massive scale fiber roll-outs. They connect thousands of users via optical fibre, aggregate their broadband traffic and send it deeper in the network. The fiber access nodes can support multiple fiber technologies including GPON, XGS-PON, 25G PON and Point-to-Point Ethernet to deliver a wide range of services with the best fit technology.
