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.”

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".

LightCounting sees demand for DCI as mega data centres go metro-regional

LightCounting forecasts in its latest Mega Datacenter Optics report that there will be growing demand for high bandwidth interconnectivity as Alibaba, Baidu and Tencent move to a distributed network of data centres in metro areas due to restrictions on building larger facilities in China, while mega data centres operated by the big western cloud companies are transforming into metro-regional clusters.

More specifically, LightCounting notes that Amazon recently disclosed that it operates 25 data centres interconnected with 3,500 fibres in Ashburn, Virginia, while Facebook has expanded its mega data centres by building new facilities near to existing ones, and Microsoft has announced it intends to build more metro and regional data centres to reduce the time involved in planning new facilities.

The research firm states that most of these facilities will be interconnected using DWDM technology, thereby expanding the market opportunity for suppliers of data centre interconnect (DCI) equipment to the cloud companies. Such customers are expected to be early adopters of 200 and 400 Gbit/s DWDM technology.

In terms of vendors, LightCounting notes that Cisco recently introduced the term 'fog computing', referring to adding compute and storage capabilities in facilities located closer to enterprises to facilitate migration of private data centres to the cloud. Meanwhile, Equinix and other colocation providers are increasing their business with enterprise customers as they migrate to the cloud.

In addition, cloud companies are beginning to use colocation data centres to extend reach closer to the end users. LightCounting notes that storage (or caching) of popular videos in local data centres or the central offices of service providers was necessary to meet rising demand for video on demand, while new applications such as SnapChat and Instagram are creating the need to support these applications locally to reduce the load on long haul networks.

The research firm adds that in the future applications such as self-driving cars and IoT will require the use of edge data centres to deliver low latency performance. All of these requirements are driving a transition in the way data centres are deployed and operated.

NTT Carriers One Petabit per Second over Single Fiber over 200 km

NTT has demonstrated a record inline optical amplified transmission of 1 petabit (1000 terabit) per second over a 205.6 km single strand of 32-core (light paths) optical fiber.

The experimental system used 32-core fiber with a new arrangement of cores to reduce inter-core light leakage, a fan-in/fan-out (FI/FO) device to couple light into the multi-core fiber, along with new digital coherent optical transmission technology. The result aws 31.3 Tbit/s capacity per core (680 Gbit/s per wavelength x 46 wavelength channels).  Multiplied by 32 cores, adn the total transmission capacity exceeded the petabit milestone.

The test was conducted in collaboration with the Technical University of Denmark, Fujikura Ltd., Hokkaido University, the University of Southampton and Coriant.

The transmission occurred within a single optical amplifier bandwidth (C-band), which is half the bandwidth used in a previous experiment the used C-band + L-band. NTT said its research indicates that it is potentially possible to carry 1 petabit per second over 1000 km, which is approximately the distance between major cities both in Japan and in Europe.

Ciena's Waveserver Ai solution allows increased capacity and service densities with minimal footprint in data centres where space may be limited. Leveraging the WaveLogic Ai coherent technology, the platform can scale to 2.4 Tbit/s in a single rack unit of space, representing a claimed 50–100% higher density compared to other compact DCI platforms. Additionally, with low power per bit performance, the solution can also help operators  reduce overall energy consumption.

Waveserver Ai can also help to simplify DCI planning and deployment leveraging a programmable coherent chipset that can be tuned from 100 up to 400 Gbit/s to optimise capacity over any distance, ranging from metro and regional to long-haul networks. As a result, with a single Waveserver Ai platform an operator can deliver single wavelength 400 Gbit/s capacity on short-haul links and 200 Gbit/s capacity for long-haul DCI applications.

Additionally, leveraging web-scale attributes the Waveserver Ai platform is designed to enable a simplified lifecycle, from planning and ordering to provisioning and maintenance, combined with a server-like deployment model. Via a suite of open APIs and management interfaces, the platform can be integrated into existing or new DCI networks and existing operational processes. Ciena noted that operators can also use its Emulation Cloud simulation environment to create, test and fine-tune customised applications.

Waveserver Ai is scheduled to be generally available in the second quarter of 2017.

RETN Deploys Infinera Cloud Xpress

RETN, which operates a backbone network that stretches over 32,000 kilometers of fiber and connects 29 countries across Europe, Asia and North America, has deployed the Infinera Cloud Xpress for connectivity between Frankfurt, Munich and Vienna.

The Infinera Cloud Xpress delivers a 500 Gb/s super-channel in a compact, two rack unit appliance for efficient transport of Ethernet services. Cloud Xpress also incorporates Infinera’s Instant Bandwidth technology to allow customers to software-activate line-side bandwidth in 100 Gb/s increments as and when needed, closely matching their end-customer demands.

RETN has been operating Infinera’s Intelligent Transport Networks for several years to enable construction, modernization and upgrade of its DWDM cross-border network ring infrastructure in Europe and Russia, including major transboundary routes across Scandinavia and Ukraine. In 2015, RETN announced deployment of 500 Gb/s super-channels using the Infinera DTN-X packet optical platform across its pan-European network. RETN selected the Infinera Cloud Xpress to provide 100 Gb/s DWDM services on two of its routes in Western Europe.

“RETN is experiencing growth in high-traffic regional networks across Europe,” said Tony O’Sullivan, RETN COO. “RETN prides itself on being an early adopter of new and innovative technologies. As we upgrade our networks, we turn to innovators in the industry bringing new solutions to the market first, like Infinera. We are delighted to have successfully deployed Cloud Xpress to power our regional networks in Western Europe, enabling us to deliver simple, scalable and reliable services for our customers.”

“RETN’s deployment of the Cloud Xpress highlights the value the Cloud Xpress Family delivers to network operators globally,” said Nick Walden, Senior Vice President, EMEA at Infinera. “The Cloud Xpress Family’s compact design, ease of use and scalability stand out, enabling operators to grow capacity rapidly while minimizing the cost of space and power.”
