At Fiber Connect 2022 in Nashville, Nokia Bell Labs showed the first proof-of-concept demonstration of 100G PON. The prototype delivers 100Gbps downstream on a single PON wavelength. The performance is achieved using digital signal processing as well optimizations of the modulation.
Nokia is also introducing the concept of a “flexible PON”, where the downstream performance can be adjusted in software based on the quality of the channel.
Stefaan Vanhastel, CTO Nokia Fixed Networks, said: “Fiber is the ultimate broadband infrastructure. It has almost unlimited capacity with only changes to the electronics at either end needed to increase speed. Today, fiber can already deliver 10G and 25G speeds. 50G will be available in the second half of this decade. With this proof-of-concept demo, we show that 100G is already within reach; all with the fiber network infrastructure that is being built today.”
Here’s the overview.
Nokia also notes that it 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. In addition, according to Dell’Oro, Nokia was the 2021 market share leader for XGS-PON equipment. Seven out of 10 fiber homes in the USA are served using Nokia FTTH kit.
Nokia milestone: 1.5 millionth Quillion-powered PON port shipments
Nokia has reached the 1.5 million port milestone for its Quillion chipset-based broadband solutions, potentially reaching 50 million subscribers.500K of the ports are 25G PON-ready.The Quillion chipset now has more than160 operator customers around the world. Designed to offer multi-PON capabilities with GPON, XGS-PON and 25G PON all running on the same fiber, Quillion also reduces energy consumption, with 50% less power needed in fiber installations…
Nokia builds mini-OLT with its Quillion chipset
Nokia introduced what it is calling the world’s smallest Optical Line Terminal (OLT) based on its Quillion chipset. The Lightspan DF-16GM OLT, which can simultaneously provide services from 1 to 25 Gbps, is designed for deployment in street cabinets in low-density areas.The mini-OLT supports GPON, XGS-PON and 25G PON. These enables the unit to cover all service types (residential, business and anyhaul) from a single solution. Nokia says the…
Vodafone tests Nokia’s 100G single wavelength PON
Vodafone completed a trial of a new Passive Optical Network (PON) technology capable of delivering speeds up to 100 Gbs on a single wavelength – the first application of flexible rate transmission in a PON network. The test was conducted in Vodafone’s Eschborn lab in Germany.The Nokia Bell Labs 100G PON prototype leveraged 25G optics in combination with digital signal processing (DSP) techniques. 25G class optics are based on mature eco-system and…
Nokia intros 25 Gbps symmetrical PON solution
Nokia introduced a 25 Gbps symmetrical PON fiber broadband solution based on its own Quillion chipset and existing next-generation PON access platform and line cards.Nokia says 25G PON will be a key technology to enable fiber to become the single infrastructure that underpins the entire telecom industry and to deliver any service to any end point. It is also the best next step for PON: it leverages the high volumes and mature eco-system of data center…
