Nokia Bell Labs demos 100G PON over a single wavelength

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.

It is also the best next step for PON: it leverages the high volumes and mature eco-system of data center...

Nokia offers network-in-a-box program for rural broadband

Nokia will begin offering Fiber-To-The-Home (FTTH) kits for expedited delivery to rural service providers. Each ‘network-in-a-box’ kit is suitable for building a network for a town of up to 1,000 homes.

Each Nokia Broadband Relief Kit is comprised of the necessary FTTH equipment, software licenses, support, and state-of-the-art in-home WiFi gateways required to serve a typical town of 1,000 households. The kits support GPON and XGS-PON over a single port and fiber using Nokia’s Multi-PON-Module (MPM) technology.

Nokia says the offer is especially valuable given the global supply chain shortages of telecommunications equipment that are impacting smaller operators

Sandy Motley, President, Fixed Networks at Nokia, said: “The pandemic magnified the importance of having broadband regardless of a household's geographical location. Families residing in rural communities, particularly those with school-aged children, suffered greatly from a lack of broadband and ability to participate in remote learning. We want to support the operators launching in hyper-localized markets but who cannot secure broadband equipment in these difficult times. In addition, we also believe that all service providers need to have one eye on the future, so all the kits can support 25G PON today or when the need arises.”

OTEGLOBE picks Infinera’s ICE6 for its European network

OTEGLOBE has selected Infinera’s ICE6 800G coherent solution for its European network. 

The deployment of Infinera’s ICE6 solution on the GX G42 Compact Modular Platform will double capacity in selected parts of OTEGLOBE's diverse terrestrial backbone network and enable the carrier to offer new 400 GbE services to its customers. 

OTEGLOBE’s pan-European network, with more than 21,000 km of fiber, spans Greece, the Balkans, Italy, and Eastern and Western Europe, and connects to major European gateways over multiple diverse fiber routes to offer unparalleled and seamless connectivity throughout the region. 

Infinera and OTEGLOBE also achieved a notable performance accomplishment leveraging Infinera’s ICE6 solution on OTEGLOBE’s resilient submarine route. Infinera’s ICE6 successfully delivered up to 16.4T of capacity over OTEGLOBE’s two unrepeatered submarine cables between Greece and Italy, each spanning approximately 350 km, which is 60% more capacity than currently available. This submarine route is a key part of OTEGLOBE’s network and increasing capacity on this segment is vital.

“OTEGLOBE boasts the most reliable backbone infrastructure in the region and has a proven record of seamlessly incorporating industry-leading technologies to meet network design best practices and continue to deliver innovative and reliable services to its customers,” said Panagiota Bosdogianni, OTEGLOBE CTO. “Infinera is a world leader in optical technology, and with its ICE6 solution on the G42 platform, significantly expands the capacity of our unique resilient backbone network routes and supports L-band operation while it also successfully addresses our requirements for lower operating costs and automation.”

“Infinera’s ICE6 solution continues to be deployed globally to provide innovative high-capacity services that are scalable, flexible, and reliable to help network operators meet growing bandwidth demands,” said Nick Walden, Senior Vice President of Worldwide Sales at Infinera. “Deploying ICE6 on OTEGLOBE’s terrestrial backbone modernizes its network and offers its customers the latest services including 400 GbE. The technology achievement successfully delivered on OTEGLOBE’s submarine route lays the foundation for upgrading and deploying ICE6 across OTEGLOBE’s entire network.”

ColorChip introduces Hairtail direct attached cable for 50G PAM

Israel-based ColorChip unveiled its Hairtail direct attached cable (DAC) technology, featuring flexibility, bending insensitivity, and the lightest cable for 50G PAM4 applications. 

This technology, when being implemented in the QSFP-DD or OSFP form factors which are made with 16 pairs of high-speed cables, may address the conventional DAC field deployment challenges due to the rigidity and rack routing with greater than 30% cost savings. 

ColorChip says the unique construction of the cable makes the typical bending radius and bending space required for conventional cable structure 50% less while twisting, bending, and zip-tying the cable demonstrates no signal integrity degradation. A Hairtail 3m QSFP-DD using a 27AWG cable offers at least 1dB margin in both insertion loss and Channel Operating Margin (COM) versus the IEEE 802.3cd. ColorChip has demonstrated the technology at DesignCon 2022 and now in full production for QSFP-DD, OSFP, QSFP56, SFP-DD, DSFP and SFP56 series.

"ColorChip's engineering innovations are driven by customers' feedback from engineering to operation. We always look into places where we may make contributions to help customers build a more robust networking through our connectivity solutions," said Yigal Ezra, the CEO of ColorChip Group. "The Hairtail technology is a great example that we are addressing the challenges that may never show up during the typical technology evaluation and deployment cycle or even initial field deployment. With this technology, we are expecting the total cost saving on the 400G networking copper connectivity would be at least 30% given the filed deployment labor savings, field failure reduction, and field maintenance cost reduction."
