Equinix tests 400G to link Paris-London data centers over Zayo

 Equinix is testing a 400G connection between its data centers in London (Slough) and Paris on Zayo’s subsea fiber network. 

As part of the trial, Zayo deployed a 500G optical channel on its 800G-enabled, DWDM network. The company used the additional bandwidth to deploy an extra 100G wave for enhanced monitoring capabilities, creating increased visibility to ensure the consistent viability of the network. The connection was able to withstand full-load testing without any traffic loss.

Zayo said the 400G technology produced many benefits by reducing hardware from four separate 100G optical cards to just one 400G card. This resulted in a simple application with fewer handoffs between the customer and Zayo, reducing the potential points of failure. Equinix streamlined operations by having fewer circuits to manage and operate its network while reducing costs. These achievements mark key differentiators for customers who build their networks around high bandwidth capacity.

As part of the trial, Zayo also reduced power consumption per gigabit by 40% compared to prior generation hardware. In addition to reducing energy costs for customers, the achievement aligns with commitments by both Zayo and Equinix to sustainable business practices and efforts to reduce environmental impacts. Zayo has also achieved efficiencies in hardware and equipment usage.

Zayo also confirmed that it is working to deliver 400G wavelength services across the majority of its U.S. and European routes by the end of 2022.

“As the first global data center platform to trial 400G, we see tremendous potential in how it will help power our next generation of services,” said Muhammad Durrani, Senior Director, Global Network Architecture, Equinix. “Our success in this trial is about more than faster speeds; it’s about the outcomes it will enable for our customers, such as achieving the low-latency requirements of critical devices transforming everything from transportation to healthcare.”

“At Zayo, not only are we focused on our customers’ connectivity needs today, we are preparing for their speed, latency, and capacity needs of tomorrow while simultaneously driving efficiencies and simplifying the overall network design,” said Yannick Leboyer, Zayo’s COO, Europe. “Equinix is sitting at the epicenter of several trends that are reshaping the industry – from digital transformation and big data to IoT and AI. Together, we’re future-proofing the ecosystem to help companies grow and innovate.”

Comcast demos 10G technologies

Comcast reached download speeds faster than 8 Gbps and upload speeds faster than 5 Gbps during a 10G event at CableLabs headquarters.

For the demo, Comcast connected a 10G-enabled Virtualized Cable Modem Termination System (vCMTS) linked by more than 80 kilometers of fiber to the demonstration site. The fiber terminated into a production switch, which connected to what is believed to be the world’s first fully functional 10G-enabled Full Duplex DOCSIS 4.0 node, along with a 10G prototype modem at CableLabs headquarters. Today’s demonstration is a first in a production-ready network environment, showing how live 10G deployments will work, orchestrated by Comcast’s Distributed Access Architecture (DAA) technology, which is already widely deployed.

“These 10G technologies represent the fastest, most efficient path to deliver multigigabit symmetrical speeds at scale everywhere, not just in select neighborhoods or towns,” said Elad Nafshi, EVP & Chief Network Officer at Comcast Cable. “The pace of 10G innovation is only accelerating, and Internet users around the world will reap the benefits.”

Comcast also demonstrated how its DAA network virtualization technology will deliver not just ultrafast 10G speeds, but also greater reliability and adaptability to support a range of next-generation network architectures. The DAA demo included two key components:

The demo showed how a single DAA-enabled vCMTS can seamlessly and simultaneously operate both 10G connections and PON (passive optical network) connections and deliver multi-gig services with identical levels of visibility and orchestration. While Comcast is primarily focused on 10G, the ability to easily blend 10G and PON provides enormous flexibility to support the widest range of geographies and customer needs.

The demo also showed how 10G and DAA will deliver greater reliability by leveraging the unprecedented visibility the technology provides into Internet performance at every level of the network from the core, all the way to individual customer gateways.

Comcast also offered a first look at a 10G node that will become a key element of 10G trials and deployments.

NeoPhotonics: strong growth in 400G, supply chain issues

NeoPhotonics reported Q1 2022 revenue of $89.3 million, up 47% year-over-year on growth in 400G and above capable products and up 11% quarter-over-quarter. Supply chain shortages negatively impacted revenue by approximately $10 million in the first quarter. 

The company said demand remains strong, but supply chain constraints are likely to persists throughout 2022 and revenue will vary based on chip supply. First quarter revenue was approximately $10 million lower due to supply chain constraints. Supply chain impacts in the quarter were primarily shortages of analog and power semiconductors. 

 

“Our business remains on a strong growth path with revenue of $89 million, 47% above the same quarter last year. Our 400G and above products grew more than 70% year-over-year, and now comprise 61% of total revenue, despite the impacts of semiconductor chip shortages. Moreover, we are now shipping production 400ZR coherent DCO module products to leading customers, and we have extended our product reach to higher speeds and to new applications, such as communications in low earth orbit satellites,” said Tim Jenks, Chairman and CEO of NeoPhotonics. “Looking forward, while we continue to see strong demand for our products, we also expect continuing challenges with IC chip supply shortages, which could materially impact our results near term.”

Mr. Jenks continued, “The Lumentum transaction, announced last November, remains on track having been approved by our shareholders and received antitrust clearance from US regulators. We believe Lumentum is an ideal partner to serve our customers on a larger scale and we look forward to securing regulatory approval in China and closing the transaction. Our 47% year on year revenue growth, non-GAAP operating profit and significant growth from western customers reflects our success in pivoting our business. We have overcome the loss of the majority of our revenue from our prior largest customer due to Department of Commerce restrictions, with growth from leading customers in high growth markets.”

Mr. Jenks concluded, “I would like to thank NeoPhotonics employees for their continued commitment, which over the years has built the Company’s strong technology leadership for high speed over distance applications and has resulted in the Company’s strong performance in the first quarter of 2022.”

CompoundTek demos hybrid Si O+C+L-Band wavelength-tunable laser

Singapore-based CompoundTek, a global foundry in emerging Silicon Photonics (SiPh), has demonstrated a hybrid Silicon O+C+L-band wavelength-tunable laser module in collaboration with a stealth-mode product company.

The company said the laser modules operated simultaneously in the O-, C-, and L-wavebands. The laser engines have a wavelength tuning range of 175 nm across the three wavebands, with an output power and side-mode suppression ratio as high as 40 mW and 50 dB, respectively.

While distributed feedback (DFB) laser arrays and microelectromechanical systems (MEMS) vertical cavity surface emitting lasers (VCSEL) have been shown to demonstrate wavelength-tuning functionality, there are limitations in terms of DFB array coupler loss and mechanical instability, respectively. Littman/Littrow-configured external cavity lasers (ECL) have also indicated wide operating wavelength range; however, the application-space of these class of lasers are limited by their bulk, as well as higher vulnerability to environmental vibrations.

CompoundTek’s Chief Operating Officer, KS Ang, said, “The challenge is for the development of a solid state-based laser diode with compact footprint, good performance that can be manufactured in a scalable, high-yield, and low-cost process. CompoundTek’s silicon photonics platform poses an attractive proposition for the realisation of the technology.”

“While there are many ways to build a tunable laser, what sets CompoundTek’s technology apart is our ability to integrate with Silicon Photonics devices which offer low propagation loss and high integration densities. Kudos to Dr. Brian Sia and the team, we are indeed very proud of this latest achievement,” he added.

More Key Findings from the 4Q21 Optical Components Report:

  • Supply chain difficulties limited Telecom optical components market growth the most in 2021. However, the segment is forecast to grow more than 8% in 2022.
  • Consumer component revenue for 3D sensing applications was flat YoY as lower-cost components offset higher unit shipments.
  • Industrial optical components used for welding and medical applications grew 18% in 2021, following a weak 2020. Following the acquisition of Coherent, II-VI is poised to control over 50% of this market.
  • 1.8M QSFP-DD Datacom modules shipped during 2021, most of which were DR4 format. The report also tracks SR4, FR4, and LR4 Datacom transceivers.
  • Over 60k 400Gbps pluggable coherent modules shipped last year, the majority of which were QSFP-DD ZR. The report captures the shipment details of all the emerging derivatives of this format, including ZR, ZR+, 0dB ZR+, and CFP2 based ZR+.
  • Shipments of 200Gbps coherent CFP2 modules grew 17% to just over 200k units during 2021 as Chinese OEMs ramp this speed (which is less dependent on western technology) for longer distance metro and long haul applications.

team.blue Denmark deploys Ciena's Waveserver Ai

team.blue Denmark has selected Ciena’s Waveserver Ai platform to serve as the foundation for its WAN-ring, providing point-to-point metro data center interconnect (DCI) network service between sites.

Ciena’s Waveserver Ai platform delivers high capacity – up to 2.4 Tb/s in a single rack unit. 

“We needed a solution to extend the capabilities of our current dark fiber infrastructure. It needed to be powerful, easy to use, and extremely stable while also being ultra-efficient in terms of power and size,” said Michael Munk Lassen, Principal Systems Architect & Head of Technology, Infrastructure, team.blue. 

“Ciena’s Waveserver Ai platform meets this need and enables us to create a simple point-to-point network between sites currently providing up to 8x100G on a single dark fiber which can be scaled further if needed.”

“Cloud and content providers across the globe are investing in their DCI capabilities to increase network efficiency, reduce energy consumption and enable highly resilient connectivity at the edge of their network,” said Jean David Fabre, Director, Datacenter Connectivity Solutions, Ciena. “Rolling out Ciena’s Waverserver Ai platform allows team.blue Denmark to provide cutting-edge services.”

Dell'Oro: Sharp decline in China optical transport equipment market

The Optical Transport equipment market contracted 2 percent year-over-year in the first nine months of 2021 due to lower sales in China, according to a recently published report from Dell’Oro Group. Outside of China, however, the demand for optical equipment continued to increase, outpacing supply.

“Optical equipment revenue in China took a sharp turn for the worse in 3Q 2021,” said Jimmy Yu, Vice President at Dell’Oro Group. “As a result, optical revenue in China declined at a double-digit rate in the quarter, resulting in a 9 percent decline for the first nine months of 2021. At this rate, we are expecting a full year optical market contraction in the country. Something that has not occurred since 2012. Helping to offset some of this lower equipment revenue from China was the robust demand in North America, Europe, and Latin America.”

“We estimate that Optical Transport equipment revenue outside of China grew 6 percent year-over-year in the third quarter. However, we believe this growth rate could have been higher, closer to 10 percent, if it was not for component shortages and other supply issues plaguing the industry. So, fortunately while optical demand is hitting a rough patch in China, it seems to be accelerating in other parts of the world,” added Yu.
