Nokia today announced its WaveFabric Elements portfolio of photonic chips, devices and subsystems, including its fifth generation coherent digital signal processor family, the Photonic Service Engine V (PSE-V).
The explosion in video and mobile bandwidth demand over the past decade has been met through the continual advancement of optical and silicon technology. But as fundamental limits of transmission capacity and processing power are approached, network operators will need new ways to continue to scale their networks to meet the surging demands of 5G and cloud networking, while containing cost. Key to this transition is 400 Gigabit Ethernet (400G) technology.
Set to become the pervasive network interface across IP, optical and data center networks, 400G marks the first common data rate since the introduction of 100G approximately 10 years ago.
As the foundational technology for high bandwidth transport, the critical task of electro-optics in the coming years will be to transport 400G services at the lowest cost across a wide range of networking applications, each with distinct size, power, and performance requirements.
Nokia’s WaveFabric Elements portfolio combines digital signal processing (DSP) and optics technologies focused on emerging end-to-end 400G applications, allowing Nokia to optimize the entire electro-optic engine that powers today’s networks and the transformational upgrades to come.
This high degree of vertical integration ensures that Nokia’s optical solutions will meet the unique economic and technical requirements of data center, metro, long haul, and subsea networks.
Nokia’s fifth generation coherent DSP family, comprising the high-performance Nokia PSE-Vs (super coherent) and the low power PSE-Vc (compact), continues Nokia’s history of developing multiple DSPs optimized for different optical networking applications, form factors, and platforms.
The new DSPs are complemented by the CSTAR portfolio of coherent optical engines brought to Nokia via its recent acquisition of Elenion Technologies, a pioneer in silicon photonics. A new family of pluggable transceiver modules allows Nokia to address their critical and expanding role in data center, IP and optical networks, as well as emerging markets and applications highly dependent upon low-cost optical connectivity, such as access and mobile networking.
Sam Bucci, Head of Optical Networks at Nokia, said, "Networks are truly at an inflection point, and 400G will be a catalyst for a significant transformation. With our WaveFabric Elements portfolio, Nokia is committed to supplying the 400G optical ecosystem with components, subsystems and design services, as well as continuing to build the highest performing optical transport solutions for the 400G era and beyond."
Scott Wilkinson, Lead Analyst at Cignal AI, said, "Nokia is one of a select few companies with the experience of building five generations of DSPs. The company’s expertise in vertical integration is a key competitive advantage in the battle for next generation coherent solutions. The focus on 400G transport in the PSE-V is well-positioned for market needs."
The CSTAR family of optical engines is currently shipping to customers. PSE-V-based platforms and pluggables will be available beginning in Q4 2020.
The Nokia WaveFabric Elements portfolio addresses the demanding power, performance, and cost-per-bit requirements of 400G networking across data center, metro, core and subsea applications.
The PSE-Vs, which can run up to 90 Gbaud, employs the second generation of the industry’s only field-proven implementation of Nokia Bell Labs-pioneered probabilistic constellation shaping (PCS). Combining refined algorithms with the enhanced capabilities of a new generation of silicon, it is capable of transporting up to 800G, while providing 60% greater reach, 40% lower power per bit, and 15% greater spectral efficiency than previous DSP generations.
The PSE-Vc enables programmable capacity from 100G to 400G with metro to long haul capability. Its extremely low power enables integration into a variety of pluggable transceiver modules.
The Nokia CSTAR family of optical engines leverages state-of-the-art silicon photonics and packaging technology, and addresses applications, including intra-data center, metro DCI and long-reach optical transport. Paired with PSE-V DSPs within Nokia platforms, they are also available independently to industry partners for integration into pluggable transceiver modules available to the broader market.
Nokia’s 400G pluggable coherent transceiver modules are optimized to address a range of platforms and applications, including Nokia’s broad portfolio of optical transport, IP, fixed access and mobile solutions. The portfolio includes 400G ZR/ZR+ capabilities in the QSFP-DD form-factor and a higher performance, more feature rich 400G multi-haul variant in a CFP2-DCO form-factor.
Nokia said will help Indian telecom provider Idea Cellular meet ever-increasing bandwidth demand by deploying Nokia's 1830 Photonic Services Switch (PSS) based Wavelength Division Multiplexing (WDM) solution.
The optical transport network solution will be implemented across fiber-constrained geographies on the Idea network in India. Once the technology is deployed, Idea will be able to provide high-bandwidth services to its subscribers.
"With the roll-out of Idea's pan-India wireless broadband network in the last one year, we have witnessed massive data growth leading to high bandwidth demand,” said Anil Tandan, Chief Technology Officer, at Idea Cellular. “We have a long standing partnership with Nokia and we are confident that Nokia will bring the same expertise and commitment in deploying optical network as it does in Radio, Core and IP domains.”
Nokia's 1830 Photonic Services Switch allows service providers to extend reach by providing a cost-effective alternative to expensive fiber. The solution will be strategically deployed in fast-growing areas to allow Idea to offer high-bandwidth services to its subscribers without worrying about the added load on the network.
Nokia WDM helps in creating a new access layer, is easily scalable and ensures optimized power consumption and space utilization. The new transport network will also be able to support the increased demand in the future.
“Through a combination of new operator offerings, aggressive data plans and continued mass adoption of smartphones, India has witnessed unprecedented data usage growth since the beginning of 2017,” said Nitin Dahiya, Head of Customer Team - Idea, at Nokia. “We are delighted to be working with Idea to deploy an optical transport network that will help address the high-bandwidth data demands of its customers.”
Telia Carrier announced that it has launched two PoPs in the Portland area in Oregon, US, bringing improved diversity and high speed connectivity to service, content and cloud providers in the Pacific Northwest.
Telia’s new PoP locations include Hillsboro, a key connection point for sea cable landings coming from the west as well as international traffic from Asia. Telia’s expansion to the Portland area gives (OTT) providers, hyperscale cloud networks and carriers the ability to directly connect in market rather than backhauling traffic to other regions, which adds latency.
The Portland metropolitan area or Silicon Forest as it is commonly referred to has become a hub for carriers and content providers as well as regional education and city networks connecting to greater Portland and Eastern Oregon. Tax incentives and green power sources have driven significant growth in the last two years. Large-scale data center construction in the region is accelerating due to terabit traffic demands and an abundance of sustainable, low cost hydro-power.
As a new market entrant, Telia Carrier’s two PoPs in the region provide unique network routing. The Hillsboro location is designed with long haul routes that establish diversity from downtown Portland, where many of the legacy carrier facilities are located. Careful selection of the routing at river crossings ensures additional reliability.
“With continued investment in large-scale data centers and as new sea cable landings come online next year to support traffic demand from the Asia Pacific region, Hillsboro is a prime location for us to introduce new PoPs,” said Art Kazmierczak, Telia Carrier’s director of business and network development.
“By expanding to Portland, we continue to deliver best-in-class IP transit performance for education and broadband customers with minimal network hops, high resilience and inherent route diversity. These capabilities ensure our customers get the best possible connectivity and ultimately, they enhance the online experience for end users.”
Orange and Nokia have achieved the world's first optical transmission of 250 Gigabits per second (Gb/s) per wavelength over 870km through Orange Poland's existing network infrastructure. This milestone was reached when a six-carrier 1.5 Terabits per second (Tb/s) superchannel occupying a bandwidth of 300GHz was transmitted between Warsaw and Wroclaw over standard single mode fibre.
The trial demonstrates how Orange Poland can stay ahead of surging bandwidth demand as cloud networking continues to grow. Optical systems typically achieve maximum transmission capacity over short distances and lower capacity across long distances. This trial demonstrated how capacity and distance can be improved in tandem using Nokia technology, resulting in a 250% increase in bandwidth over commonly deployed 100Gb/s networks using the same amount of spectrum.
"At Nokia we continue to push the limits of optical technology with our customers. The massive bandwidth demands brought on by cloud networking - and the anticipated continued growth of that demand - means we never stop innovating,” said Sam Bucci, head of Nokia's Optical business. “Our recently announced photonic engine, the PSE2, and our 500G muxponder, in combination with Orange's talented engineers and rock solid network infrastructure, made this technical feat possible. We're proud of this accomplishment and look forward to more innovation as the telco cloud network takes hold."
The 1.5Tb/s superchannel is based on six carriers of 250Gb/s capacity each. With electrical speed 30% faster than current technology, the capacity is maximized while the channel spacing remains aligned with the 50 GHz ITU-T grid. The field trial used an 870km fibre link with flexible grid infrastructure and standard erbium-doped fibre amplification applied to 20dB spans of standard single mode fibre. The size of the superchannel and its 50GHz spacing between channels, which is the same as existing 100Gb/s channels, will ease network planning and operation.
Orange and Nokia also demonstrated with a real-time transponder a record spectral efficiency of 5 bits/Hz with 250Gb/s in 50GHz over 870km by using 16QAM modulation format. The new optical link could transmit up to 24Tb/s of traffic in total if 96 channels amplifiers were used.
"This ground-breaking milestone will be the basis for faster networks and a better user experience for our customers,” said Christian Gacon, Vice President in charge of Orange's transport networks. “Bandwidth demands are continuing to skyrocket, but we also need to keep our infrastructure costs in check. Reaching these new heights in optical transmission proves we can meet bandwidth demand while maintaining the lowest cost per bit so our business can continue to flourish."
