Nokia demos 100Gb/second broadband technology


Finnish telecommunications vendor Nokia’s research arm, Nokia Bell Labs, is presenting the first 100Gb/second broadband technology at Fibre Connect 2022 at Nashville, Tennessee.

Nokia achieved this speed using 100G PON technology and will be showing the prototype in the proof-of-concept area at the event.

Nokia is NBN’S FTTP/GPON vendor.

The prototype delivers 100Gb/s speeds in downstream on a single PON wavelength, avoiding the need to combine multiple wavelengths carrying lower speeds. Its parameters mimic real-world conditions including fibre distances and power split.

While speeds up to 25Gb/second are possible on existing optical technologies, higher speeds new require approaches.

The Fibre Connect prototype is using advanced digital signal processing (DSP) techniques needed for all technologies beyond 25G, 50G, and 100G PON. Nokia claims the demonstration showcases flexible data rates.

“With this proof-of-concept demo, we show that 100G is already within reach; all with the fibre network infrastructure that is being built today,” comments Nokia fixed networks chief technology officer Stefaan Vanhastel.

Nokia was the first telco equipment vendor to enable 25G PON on the same OLT equipment that is being deployed today for GPON and XGS-PON. Market research firm Dell’Oro Group in its quarterly reports positioned Nokia as the 2021 market share leader for XGS-PON equipment.

Seven out of 10 fibre homes in the US are served using Nokia FTTH kit.
