Cignal AI: North American optical sales rebound in 2019

Sales of optical equipment in North America rose more than 25% for 4Q19 and 10% for all of 2019, according to the most recent Transport Hardware Report from research firm Cignal AI.

The North American packet market for Access and Aggregation routing devices also grew strongly in the fourth quarter as demand for Edge and Core switching and routing dropped off dramatically. 5G and other access rollouts boosted growth in the Access and Aggregation market segment.

“After three years of North American spending declines as operators focused capex on wireless and access, optical hardware sales for the region revived and grew at a healthy pace for 2019, while packet hardware sales remained flat,” said Scott Wilkinson, Lead Analyst at Cignal AI. “Market leaders Ciena, Infinera, and Cisco all achieved optical sales growth of more than 25% in 2019.”

Some highlights:

  • Long haul optical spending reached record levels in 2019. Growth slowed in 4Q19 but the segment finished the year up over 10%.
  • Transport equipment sales in China declined slightly in 4Q19 as packet sales declined and optical sales growth cooled to single digits. When adjusted for the influence of ZTE’s shutdown in 2Q18, optical hardware sales grew less than 10% in 2019.
  • Japan ended an extraordinary year of optical sales growth up 25% in Q4 and almost 40% in 2019.

Fujitsu's TransLambda delivers 3X optical capacity in C-band

Fujitsu Network Communications unveiled TransLambda technology,  an ultra-high capacity, wavelength-division multiplexing (WDM) multiband transmission system (MTS) that substantially expands the transmission capacity of optical fiber networks without deploying new L- and S- band dedicated transceivers.

Fujitsu's TransLambda packs multiple transmission bands into a single fiber using all-optical wavelength conversion (AOWC). TransLambda enables up to three times the capacity for data center interconnect (DCI) and long-haul transport networks. Specifically, TransLambda fiber capacity multiplier technology offers ultra-high capacity — up to 76.8Tb/s of data using 192 channels at 400G speeds per 75GHz channel — in a plug-and-play blade using C-band transponders.

The company said this 3X boost is particularly crucial for those applications where C-band transmission is the only available option for the foreseeable future, such as optical links that use direct-attach or transponder-attach ZR/ZR+ pluggable coherent optics.

The Fujitsu TransLambda Test Kit, which is currently being used in customer lab trials, is offered in a single blade configuration that can be used with any legacy WDM network architecture including multi-vendor systems.

“TransLambda technology is just the latest in a line of innovations from Fujitsu to achieve the highest network speed and capacity as cost-efficiently as possible, helping our customers gain true competitive advantage in today’s demanding marketplace,” said Paul Havala, vice president of global planning at Fujitsu Network Communications. “Our TransLambda fiber multiplier approach is a much more cost-efficient way to achieve significant capacity increases without installing L-band equipment, addressing cost and operational overhead while seamlessly integrating into existing network architecture to fully leverage deployed fiber assets.”

Dell'Oro: DWDM systems revenue grew 8% Y/Y in 1H19

The market for DWDM systems significantly grew year-over-year (Y/Y) in the first half of 2019, according to Dell'Oro Group, in part because the comparative period, 1H 2018, includes much lower sales into China caused by the US ban on ZTE.



Some highlights:

  • In 1H 2019, Ciena held nearly 30 percent share of the optical DWDM market outside of China due to the company’s dominance in North America and growing share in international markets. 
  • Ciena’s revenue grew over 20 percent Y/Y. 
  • During this period, Huawei held the second-highest share outside of China even though the company’s market share declined slightly from both full-year 2018 and 1H 2018. 
  • Nokia continued to hold the third-highest share outside of China with revenue growth in the period exceeding the market average percentage growth of 5 percent.

ADVA hits new benchmarks for bandwidth/reach on terrestrial long-haul

ADVA announced new benchmarks for bandwidth and reach on terrestrial long-haul using its FSP 3000 TeraFlex platform.

The new records were achieved in a commercial long-haul terrestrial network originally built for 100Gbit/s services. ADVA’s partners included the Poznan Supercomputing and Networking Center (PSNC), EENet of HITSA and Tele2 Estonia.

Using an optical spectrum-as-a-service approach, the terminal achieved 200Gbit/s per wavelength transmission over a distance of 5,738km with 2.5bit/symbol, and 500Gbit/s over 1,016km with 5bit/symbol modulation. Record-breaking results also included 300Gbit/s per wavelength transmission over 3,751km with 3bit/symbol, and 400Gbit/s per wavelength across 1,792km with 4.5bit/symbol modulation. Feasibility of 800Gbit/s transmission over 1,016km in a single 125GHz spectral slice was also demonstrated.

ADVA said one of the keys to achieving this performance is the ability of the FSP 3000 TeraFlex to utilize network telemetry and fractional QAM to maximize reach and capacity through the automated configuration of modulation format and baud rate.

The trial also highlighted how a disaggregated open line system (OLS) approach can enhance network flexibility and leverage the most value from existing optical infrastructure.

“Our terminal technology is now redefining terrestrial long-haul data transport. Just as we proved in trials with DCI and metro networks, the software-defined transmission of our FSP 3000 TeraFlex™ is the ultimate response to soaring bandwidth needs,” said Jörg-Peter Elbers, SVP, advanced technology, ADVA. “With its programmable signal shaping and ultra-flexible modulation capabilities, our unique solution balances distance and capacity for maximum spectrum utilization and optimal performance over any reach. This gives communication service providers the power to massively increase bandwidth without the expense of a major upgrade. This demo also shows how an open coherent optical layer removes all restrictions, even when interconnecting across multiple countries. And, with our FSP 3000 TeraFlex deployed as part of a disaggregated OLS solution, it delivers complete agility for best cost efficiency.”

TIM carries 550G wavelength with Nokia's Photonic Service Engine 3

 Nokia, in collaboration with Telecom Italia (TIM), set a new European record for data transmission over a long-distance backbone network -- a wavelength speed of 550 Gbps carried more than 350 km on TIM's operational network between Rome and Florence. In addition, TIM and Nokia carried a 400G wavelength over 900 km between Rome and Milan, and a 300 Gbps wavelength over 1,750 km.

The trial used the new Nokia Photonic Service Engine 3 (Nokia PSE-3). TIM'a DWDM backbone is based on the latest generation of Nokia's 1830 Photonic Service Switch.  The network is fully automated and currently carries optical signals with a capacity of 100 Gb/s over distances of up to 1,800 kilometers, and 200 Gb/s up to 800 kilometers. The backbone, with a coverage of over 16,000 kilometers of fiber, and connecting to 65 national POPs (Point of Presence), has carried over 9,000 petabytes of data traffic in the last year.

Elisabetta Romano, Chief Technology & Innovation Officer at TIM, said: "We are proud of this European record which confirms TIM's technological leadership, the high quality of our network, our commitment to develop innovative solutions in order to guarantee the best experience to our customers. Today's result, which triples transmission speed compared to the current one, confirms that TIM's network is the most advanced infrastructure capable of offering new digital services and platforms, also with a view to developing 5G."

Germany's M-net tests Nokia's probabilistically shaped wavelengths

M-net Telekommunikations GmbH, a German service provider, has conducted the first field trial of probabilistically shaped wavelengths using Nokia Photonic Service Engine 3 (PSE 3) super coherent technology. 

Specifically, M-net and Nokia enabled a 500 Gbps, single, probabilistically shaped wavelength over a regional DWDM network spanning the German state of Bavaria.

M-net used probabilistic constellation shaping (PCS) to shape the signal from its maximum capacity of 600G to a rate optimized for the specific fiber route used in the test.

Dr. Hermann Rodler, CTO at M-net, said: "This field trial clearly underlines the innovative strength of M-net. We are very proud to collaborate with Nokia to push the technology envelope on our state-of-the-art fiber-optic network, and to be the first carrier to publicly test the PSE-3 and its probabilistic constellation shaping technology."

Sam Bucci, head of optical networking at Nokia, said: "We're excited to partner with M-net on the implementation of its new fiber optic backbone network. The Technical University of Munich played a key role in the development of PCS, and the PSE-3 was largely developed at Nokia's R&D facility in Nuremberg, so it's only appropriate that the first field trial of PSE-3 technology would take place in Bavaria."

Nokia's PSE-3 chipset leverages probabilistic constellation shaping

Nokia unveiled its Photonic Service Engine 3 chipset featuring probabilistic constellation shaping (PCS) that pushes fiber-optic performance close to the Shannon limit to fully exploit channel capacity.

PCS is a new modulation technique pioneered by Nokia Bell Labs that the company says enables maximum capacity over any distance and on any fiber - from metro to subsea - increasing capacity up to 65% over currently deployed networks while reducing power by 60%. This includes 200G rates over most terrestrial and subsea links, as 400G over most shorter distances.

The PSE-3 chipset, which is the first coherent digital signal processor to implement PCS, provides finely adjustable wavelength capacity from 100G to 600G with a single, uniform modulation format, baud rate, and channel size. This simplifies network operations and planning.

"This is a breakthrough in how we can maximize the performance of optical networks and, at the same time, vastly simplify operations. The Photonic Service Engine 3 is the culmination of a decade of research and first-hand experience building the largest, highest capacity optical networks in the world. By introducing this extreme and yet remarkably simple programmability, our customers can now maximize the capacity of every link in their network, whether that's 10 km, 10,000 km or beyond. They will be able to keep their costs under control while handling the huge bandwidth demands that video, cloud, and soon 5G will be throwing at them."

Nokia is planning to introduce the PSE-3 chipset across ist packet-optical portfolio, including a new version of the 1830 Photonic Service Interconnect, a compact modular WDM platform for data center interconnect. The 1830 PSI-M will use modular chassis architecture with high-performance modules based pm the PSE-3. Commercial availability is expected in Q3 2018.

IX Australia deploys Smartoptics’ low cost 100G Open Line System

Internet Exchange Australia (IX Australia) has deployed Smartoptics' DCP-M40 Open Line System and Pluggable DWDM QSFP28 PAM4 transceivers to provide high capacity links to metro locations in Sydney.

The new, automated, network was delivered by Independent Data Solutions (IDS) and provides IX Australia with lowest cost 40 x 100 Gb/s traffic capability over a single pair of fibers.

The new Smartoptics DCP-M40 Open Line System enables up to 40x100G wavelengths over spans exceeding 50km with fully automated addition of new channels for ease of use.

Oslo-based Smartoptics AB said space and power considerations were important factors in the technology choice due to the cost of colocation and available power in hosting facilities. The 1U form factor and max 45W power consumption for a fully loaded 40 channels system were significantly differentiating factors over more traditional coherent transponders. 

Magnus Grenfeldt, CEO Smartoptics, commented, “In winning this important network expansion project, Smartoptics demonstrates continued success in commercializing PAM4 technology, our unique open line system and network automation technology as new foundation for Data Centre Interconnectivity. IX Australia has seamlessly expanded the capabilities of its network selecting the most optimal technology for their interconnects. Selecting PAM4 over coherent technology for less than 80km interconnects is clearly significantly advantageous in terms of cost, complexity, availability and latency.”

Ekinops debuts flexible line rate modules

Ekinops based in Lannion, France, a global supplier of next-generation optical networking equipment, introduced two new flexible rate line modules for its optical transport platform in metro, regional or long-haul deployments.

The two new modules – the PM 200FRS02 and PM 200FRS02-SF – employ dual QSFP28 client ports with software-selectable line side modulation that can be provisioned as either DP-QPSK or 16QAM to create 100G or 200G transport links. The new generation modules occupy only one-third the space of previous equipment, occupying only a single slot in an Ekinops 360 chassis, for three times the capacity per shelf. This makes it possible to fit up to 1.2 terabits per second of capacity in only two rack units. In addition, the PM 200FRS02-SF provides single fiber operation, giving service providers the option of cutting fiber costs in half.

Ekinops is also adding to the flexibility of the modules by introducing the PM 100G-AGG companion card for multiplexing up to ten 10G multiprotocol client services into a G.709 standard OTU4 that connects to one client port on the PM 200FRS02 or PM 200FRS02-SF.

Ekinops said its new modules will help service providers to reduce their capital and operational costs, improving the business case for deploying new capacity.

Aire Networks, which is Spain's fourth largest wholesale operator, is now using the Ekinops modules in its 27,000-kilometer fiber network that covers 90 percent of the country. The single fiber capability was key for Aire Networks, which was looking for a solution supporting 200G transmission in single fiber mode.

“We have been able to reduce the form factor in these new modules by a factor of three while reducing power requirements by a factor of two. That delivers an order of magnitude improvement in service density and network cost, key factors for Aire Networks and for other Ekinops customers when it comes to profitability,” said Mark Burton, EMEA Vice President of Sales at Ekinops. “This demonstrates Ekinops’ continued commitment to providing our customers the most efficient and flexible optical transport solutions.”

Infinera intros Auto-Lambda tuning for DAA cable networks

Infinera introduced an Auto-Lambda capability to simplify Distributed Access Architecture (DAA) for cable network operators.

Auto-Lambda provides auto-tuneable 10 Gb/s DWDM automation for optical cable access networks. The capability, which operates over up to an 80-kilometer reach over both single and dual fibers, addresses the need for a “plug-and-go” installation model for service activation. First, central office equipment is configured to a desired wavelength. Later, when a field technician installs the customer premise equipment, Auto-Lambda ensures that the proper wavelength is selected automatically, significantly simplifying the installation. This will enable network operators to scale to extremely large numbers of 10G access points.

The capability is expected to be available in the Infinera XTM Series in the first half of 2018.

Infinera said its Auto-Lambda technology builds on its experience deploying optical networks for several of the top cable operators across North America and Europe.

“With our history of innovation in DWDM access and cable networks, we are excited to directly address DAA,” said Sten Nordell, CTO, Infinera Metro Business Group. “Auto-Lambda demonstrates our ability to greatly simplify access network operations for next-generation cable network architectures.”

ECI announced the continued deployment of its 400 Gbit/s solution to enable faster connectivity and meet growing bandwidth demand, with projects at key customers across Europe that have upgraded their networks using ECI's Apollo family of optical products with integrated 400 Gbit/s flex-grid blade.

ECI's Apollo platform is designed to enable service providers to meet current and future demand. The platform combines high-capacity, low-latency OTN transport and switching with software configurable, colourless, directionless and gridless optical routing, for enhanced efficiency. Equipped with the 400 Gbit/s blade, the solution allows for the flexible allocation of transmission rate and spectrum in accordance with service type, preference or distance.

In addition, the ability to configure a mix of rates on both client and line sides provides customers with improved efficiency and flexibility and reduced costs.

ECI cited companies that have recently implemented its 400 Gbit/s solution including:

  • The Dutch National Research and Education Network SURFnet, which established a 400 Gbit/s connection between Utrecht and Breda as part of an upgrade of its next generation network, SURFnet8. The link provides a direct connection, with high capacity to support the transfer of information between educational and research organisations at two major university cities.

  • German service provider NetCom BW, which already operates a major Apollo network, launched the 400 Gbit/s platform to provide a link between Stuttgart and Frankfurt, which will serve as the basis for a direct connection to Internet Exchange Frankfurt; the solution also allows for future growth via up to 88 parallel connections.

  • Romanian cable TV operator UPC, which has deployed the Apollo platform in its core ring that services the main cities in Romania such as Bucharest, Brasov, Cluj, Oradea and Timisoara. The Apollo 88 channel ring provides 400 Gbit/s connectivity with 100 Gbit/s service interface, replacing 10 Gbit/s interfaces.

  • German data centre operator New Telco, an ECI customer for nearly a decade, which deployed ECI's Apollo DWDM technology across the Frankfurt metro area to upgrade the existing 100 Gbit/s interfaces to 400 Gbit/s to provide higher port density and throughput.

Infinera achieves 19 Tbit/s capacity on trans-Atlantic route

Infinera announced the completion of a submarine field trial with a major subsea network provider over a modern trans-Atlantic route that involved the Infinera XTS-3300 meshponder and demonstrated the potential to support 19 Tbit/s per fibre pair, achieving what it claimed is the highest spectral efficiency on a trans-Atlantic route with stable, commercial-ready performance margin.

Infinera's XTS-3300 leverages its new Infinera Infinite Capacity Engine 4 (ICE4) and comprises part of the Infinera Intelligent Transport Network portfolio optimised for long-haul subsea applications. The new meshponder delivers the performance of Infinera's ICE4 technology, including enhanced pre- and post-dispersion compensation, digitally synthesised Nyquist subcarriers and soft-decision forward error correction (FEC) gain sharing.

The trial over the trans-Atlantic link was designed to validate ICE4's transmission of 8QAM 600 Gbit/s super-channel in 140 GHz of spectrum, delivering what is claimed to be the highest spectral efficiency of 4.3 bits per second, per hertz together with commercial-ready performance margin.

The ICE4-based Infinera DTN-X XT Series and XTS Series are expected to be generally availability later in the quarter. Infinera's Cloud Xpress 2 platform, also based on ICE4, began shipping in the second quarter of 2017.

Commenting on the field trial, Andrew Schmitt, lead analyst at Cignal AI, said, "While optical vendors have demonstrated experimental approaches to boost subsea fibre capacity, the Infinera XTS-3300 is the first commercial platform to deliver over 19 Tbit/s capacity on a trans-Atlantic route… the XTS-3300 trial used tighter channel spacing and advanced compensation techniques in the DSP".


  • Infinera unveiled its Infinite Capacity Engine, a multi-terabit optical subsystem in 2016, combining its next generation FlexCoherent Processor and the photonics of its fourth generation photonic integrated circuit (PIC). The technology enables optical super-channel capacity of up to 2.4 Tbit/s and reach up to 12,000 km in a single compact package.
  • The solution also features Advanced Coherent Toolkit (ACT), providing a claimed 60% more capacity-reach performance for submarine and terrestrial networks versus current generation optical technologies.
