DustPhotonics and MaxLinear demo silicon photonics + integrated lasers

DustPhotonics and MaxLinear demonstrated a silicon photonics chipset with integrated lasers directly driven from a DSP without the use of any external driver chip.

The MaxLinear Keystone DSP (Digital Signal Processor) and DustPhotonics Carmel Silicon Photonics chip were shown together to support direct-drive operation, which reduces the overall cost and power dissipation of optical transceivers for data communication. 

Potential applications include 400 Gbps and 800 Gbps pluggable modules and on-board optics.

The DustPhotonics chip includes an integrated DFB (Distributed-feedback) laser and DustPhotonics Low Loss Laser Coupling technology (L3C), achieving a very efficient coupling of light into the Photonic Integrated Circuit (PIC). This unique technology enables the use of 1 laser for every 4 channels.

The MaxLinear Keystone chip is part of a family of DSPs capable of both 400 Gbps and 800 Gbps operation, based on TSMC’s 5nm process. The Keystone DSP provides a rich set of features for transceivers, CPO (Co-Packaged Optics) modules and on-board optics while achieving significantly lower power than competitive solutions. The integrated drivers are optimized for silicon photonics direct-drive and provide the best industry performance for this application.

The companies say their combined solution enables performance that significantly exceeds all IEEE specifications. In terms of power consumption, 400 Gbps transceivers can now be designed to reach sub 7W.

“DustPhotonics is focused on enabling best-in-class Silicon Photonics chips to simplify the efforts of transceiver and systems designers,” said Yoel Chetrit, Vice President R&D of DustPhotonics. “Not only can our Carmel chip simplify the overall system design by reducing the total number of lasers to a single laser for 4 channels, but it also eliminates the external driver, which reduces the cost, power and complexity of the overall system.”

“The combination of our Keystone 5nm integrated driver DSPs with DustPhotonics’ silicon photonics demonstrates the significant power and performance advantages achievable with our integrated drivers,” said Drew Guckenberger, Vice President of Optical Interconnect at MaxLinear. “With double-digit year-on-year growth in market demand for 400Gb/s and 800Gb/s transceivers, this integrated solution can create tremendous value for our customers. We look forward to seeing full transceiver deployments in the near future.”

FCC rejects Starlink for RDOF funding

The FCC rejected the long-form applications of Starlink and of LTD Broadband to receive support through the Rural Digital Opportunity Fund program. 

Starlink is delivering broadband access via thousands of LEO satellites. 

LTD Broadband offers a fixed wireless access service and has built over 2500 tower sites covering over 50,000 square miles of Iowa, Minnesota, Missouri, Nebraska, North Dakota, South Dakota, Tennessee, and Wisconsin. 

The FCC said these applications failed to demonstrate that the providers could deliver the promised service.

“After careful legal, technical, and policy review, we are rejecting these applications. Consumers deserve reliable and affordable high-speed broadband,” said Chairwoman Rosenworcel. “We must put scarce universal service dollars to their best possible use as we move into a digital future that demands ever more powerful and faster networks. We cannot afford to subsidize ventures that are not delivering the promised speeds or are not likely to meet program requirements.”

“Starlink’s technology has real promise,” continued Chairwoman Rosenworcel. “But the question before us was whether to publicly subsidize its still developing technology for consumer broadband—which requires that users purchase a $600 dish—with nearly $900 million in universal service funds until 2032.”

In the initial auction results announced December 7, 2020, LTD Broadband won $1,320,920,718.60, and Space Exploration Technologies Corp. (Starlink) won $885,509,638.40.

In rebuttal, FCC Commissioner Brendan Carr issued the following statement: “I am surprised to find out via a press release—while I am on a work trip to remote parts of Alaska—that the FCC has made this significant decision. I will have more to say because we should be making it easier for unserved communities to get service, not rejecting a proven satellite technology that is delivering robust, high-speed service today. To be clear, this is a decision that tells families in states across the country that they should just keep waiting on the wrong side of the digital divide even though we have the technology to improve their lives now.”

  • Separately, the FCC  announced that is ready to authorize $21,112,263 in broadband funding to three companies to deploy gigabit service to almost 15,000 locations in four states Tennessee, Texas, Utah, and Wyoming.
  • To date, the RDOF program has authorized more than $5 billion in funding to bring primarily fiber gigabit broadband service to over 3,000,000 locations in 47 states.

Dell'Oro: Smart NICs to drive Ethernet adapter market to $5B by 2026

 Driven by SmartNICs, the Ethernet Controller and Adapter market is expected to reach $5 Billion in 2026, according to a new report from Dell'Oro Group. Server network connectivity will transition to higher speeds, with 100 Gbps and higher-speed ports accounting for 44 percent of the shipments in five years.

“We predict Smart NICs will account for 38 percent of the total Ethernet Controller and Adapter market by 2026,” said Baron Fung, Research Director at Dell’Oro Group. “Smart NICs will displace traditional NICs for most of the hyperscale cloud infrastructure for general-purpose and high-end workloads such as accelerated computing. There are also opportunities for Smart NICs in the Tier 2 Cloud, Enterprise and Telco segments, with compelling use cases such as network protocol offloads, distributed storage, and virtualized network security applications. However, vendors would first need to address cost-of-ownership and implementation challenges before we see broader Smart NIC adoption outside of the hyperscale cloud market,” added Fung.

Additional highlights:

  • Total Ethernet Controller and Adapter market revenue is forecast to grow 10 percent by 2026.
  • 100 and 200 Gbps will be the dominant server port speeds for the Top 4 US Cloud SPs—Amazon, Google, Meta, and Microsoft—over the next five years.
  • Smart NIC revenues are projected to grow at a 21 percent compound annual growth rate over five years, compared to 5 percent growth for traditional NICs.

Australia's TPG Telecom deploys Adtran's Gfast

TPG Telecom Group (TPG), Australia’s second-largest telecommunications provider, is leveraging the Adtran second generation Gigabit Gfast fiber extension portfolio to upgrade existing broadband services to Gigabit speeds and attract new subscribers.

Adtran is enabling TPG to rapidly roll out Gigabit broadband services to more than 230,000 premises and over 2,000 buildings across Eastern Australia.

TPG has a large footprint of both single- and multiple-dwelling locations that were connected by VDSL technology. The service provider wanted to offer Gigabit services to these existing subscribers as well as everyone else in its DSL services footprint. TPG is the first major telco in Australia to deploy Gfast and it selected Adtran’s latest Gfast technology to rapidly launch fast, competitive broadband service speeds that are 10 times faster than similar services offered by competitors in the region.

“In today’s global digital economy, having access to Gigabit services is a big competitive advantage for any carrier that wants to offer the best connectivity solutions to residential and business customers. The launch of Gfast has helped us offer some of the fastest broadband speeds available in Australia today and will be a game-changer for TPG’s wholesale business and customers,” said Jonathan Rutherford, Group Executive, Wholesale, Enterprise and Government at TPG Telecom Group. “We’ve been proud to work with Adtran—it has overcome global component supply constraints to ensure we were able to quickly and efficiently roll out this new technology.”

Adtran’s Gfast VDSL coexistence technology enables Gfast-based services to uniquely support the delivery of symmetric and asymmetric Gigabit speeds even when delivered in coexistence with legacy VDSL2 services.

Dell'Oro: Wireless LAN market impacted by backlogs

The overall market for enterprise wireless LAN equipment is expected to exceed $10 billion by 2026, and see a healthy CAGR over the next five years, according to Dell'Oro Group.  However, enterprise Wireless LAN backlogs will balloon to over 100 percent of revenues in 2022, leaving companies to get inventive in their search for Wi-Fi coverage.  A boost in unit shipments is not expected until late 2023, with a return to normal unit growth still two years away.

“Wireless LAN market sales are being dragged down by manufacturers’ record-breaking backlogs,” said Si├ón Morgan, Wireless LAN Research Director.  “Our recent interviews have revealed that the lead time for receiving Wireless LAN Access Points has stretched to between six months and a year – a significant change from the ‘weeks-to-months’ that enterprises were waiting at the end of 2021. Supply constraints have shifted, including not just the main Wi-Fi chips but also secondary or even tertiary components.  With a limited ability to fulfill the orders flooding in, manufacturers will focus their late 2022 and early 2023 shipments on working down outstanding backlogs:  mainly orders for Wi-Fi 6.  Unit shipments should start to loosen up later in 2023, about the time Wi-Fi 7 appears on the market.

“Enterprises are going to creative lengths to procure Wi-Fi solutions, such as prolonging existing support contracts, using older equipment or even repurposing consumer-grade routers. Systems integrators are recommending ways to enable more applications, squeezing more value from the existing network infrastructure. In sum, now is a time characterized by invention,” added Morgan.Additional highlights from the Wireless LAN July 2022 5-Year Forecast Report:

  • A calculation on published backlog levels of manufacturers outside China reveals order books swell to over ten times their normal level, exceeding the size of their annual revenues.
  • This year’s market growth of nine percent will be mainly fueled by price increases, with unit shipments remaining constrained. Increased prices will boost 2023 revenues as manufacturers pass on higher costs, but price erosion will begin to take hold in 2024 and beyond.
  • The first enterprise-class Wi-Fi 7 shipments in the fourth quarter of 2023 are predicted to dampen the take-up of Wi-Fi 6E.
  • While the adoption of public cloud-managed Wireless LAN will expand, a substantial portion of customers will prefer private cloud and on-premises solutions as enterprises reevaluate their cloud strategy.
