Arista debuts 32-port 400G Ethernet switches

Arista Networks introduced its first two switches supporting 400 Gigabit Ethernet and designed for high-density leaf spine data center networks, including 100G connectivity to servers and 400G connectivity in the leaf-spine fabric.

Both of the new Arista 7060X4 Series switches are based on the Broadcom 12.8 Tbps Tomahawk 3 silicon, support 32 400G ports in a compact 1U chassis. In addition, each 400G port can be split into four 100G ports, which supports a total of 128 100G ports in a 1U chassis.

The switches uses industry-standard optics for 400G and offers the choice of two optical module form factors - OSFP and QSFP-DD. Both form factors offer a wide choice of 400G optics and cables, including optics that provide backward compatibility for 100G ports.

“We are delighted to introduce our first 400G switching platforms delivering four times the throughput, double the price/performance and double the power efficiency of our previous 100G platforms,” said Andreas Bechtolsheim, Arista’s Chairman and Chief Development Officer. “These products will address pent up demand for more bandwidth in cloud networks, allowing cloud service providers to build much more scalable networks.”

Arista said both switches are fully qualified for its EOS.

Highlighted features:

  • Enhancements in Arista EOS traffic management and load balancing take advantage of on-chip improvements in buffering and routing resources.
  • 4X increase in bandwidth density compared to existing 100G 1U switches
  • Optimized shared buffer to lower application latency for AI and storage workloads
  • Elephant Flow Detector for advanced traffic management
  • Traffic awareness with Dynamic Load Balancing and Dynamic Group Multipath to improve performance in large cloud and HPC networks
  • Increased routing capacity combined with 2X IO increase for hyperscale leaf-spine
  • Low power optimized with uncompromised performance at 12.8 Tbps
  • Consistent EOS support including cloud-based automation, analytics and availability
  • Choice of OSFP and QSFP-DD optics supporting 50G/100G/200G and 400G speeds
  • Moving network tiers to 400G with high density 100G compute maximizes the performance of next-generation applications such as artificial intelligence, machine learning, and server-less compute through greater network speeds and by eliminating oversubscription between leaf and spine tiers.


OIF completes Flex Ethernet and Common ACO Electrical I/O agreements

The OIF announced three Interoperability Agreements (IAs) aimed at expanded interoperability of Flex Ethernet and increased data rates. These include:

FlexE 2.0 -- initiated in 2016, the FlexE 2.0 project enables equipment to support new Ethernet connection types and FlexE allows network providers and operators to utilize optical transport network bandwidth in more flexible ways. FlexE can deterministically utilize the entire aggregated link, creating a more efficient alternative to the traditional IEEE 802.3ad or IEEE 802.1-based Link Aggregation (LAG) solutions which often can only utilize 70-80% of the available bandwidth. Key features of the FlexE 2.0 project include adding support for FlexE groups composed of 200GBASE-R and 400GBASE-R PHYs, in addition to groups composed of 100GBASE-R PHYs, and adding an option for the support of time and frequency synchronization at the FlexE group level.

FlexE Neighbor Discovery -- this project recognizes that FlexE capability discovery is still required to facilitate the setup of FlexE groups and clients. The project introduced some extensions to the Link Layer Discovery Protocol (LLDP) for FlexE capability discovery. It enables remote FlexE PHY and deskew capability discovery, PHY connectivity discovery and verifications, and FlexE Group subgroup integrity verification.

Common ACO Electrical I/O Project -- this implementation agreement follows the success of the CFP2-ACO optical transceiver implementation agreement but is form factor agnostic, so it also benefits analog coherent modules based on such form factors as CFP4, CFP8, QSFP, microQSFP, QSFP-DD and OSFP. The project defines the ACO electrical I/O independent of the choice of form factor and optical carrier count for 45 Gbaud and 64 Gbaud per-carrier applications.

“The completion of these projects reinforces OIF’s commitment to provide the industry with the flexibility and increased bandwidth solutions combined with increased data speeds it requires to keep up with market demands and drive solutions that enable the next generation of networks,” explained Dave Stauffer of Kandou Bus and OIF’s Physical and Link Layer (PLL) Working Group Chair.

FCC eyes 1200 megahertz of spectrum in 6 GHz band for unlicensed use

The FCC is proposing to make up to 1200 megahertz of spectrum in the 6 GHz band (5.925-7.125 GHz) available for use by unlicensed devices.

The FCC said its proposed rules will allow unlicensed devices to operate in the 6 GHz band without interfering with the operation of the licensed services that will continue to use this spectrum. 

In those portions of the 6 GHz band that are heavily used by point-to-point microwave links, the FCC proposes to allow unlicensed devices to operate where permitted by an automated frequency coordination system and invites comment as to whether this is necessary for devices operated only indoors.  In the other portions of the band where licensed mobile services, such as the Broadcast Auxiliary Service and Cable Television Relay Service, operate, the unlicensed devices would be restricted to indoor operations at lower power. 

FCC Commissioner Jessica Rosenworcel stated: "Today, Wi-Fi adds more than $500 billion to the United States economy every year—and $2 trillion globally.  It has democratized internet access, helped carriers manage their networks, and fostered all sorts of wild innovation.  In fact, it’s the perfect sandbox for experimentation, because access does not require contract or permission. As exciting as this is, it means the airwaves used by Wi-Fi are getting crowded.  Already our current Wi-Fi bands are congested because they are used by more than 9 billion devices.  By the end of the decade, we will see as many as 50 billion new devices connecting to our networks through the internet of things.  Add this up.  We’re going to need a significant swath of new unlicensed spectrum to keep up with demand. Now is the time to do something about it." 


FCC looks to open 3.7 and 4.2 GHz for 5G

The Federal Communications Commission has identified up to 500 megahertz of mid-band spectrum between 3.7 and 4.2 GHz that could be open for 5G wireless services.

A newly adopted FCC order sets forth several steps toward making more mid-band spectrum available for terrestrial fixed and mobile broadband use.  Specifically, the Order will require Fixed Satellite Service earth stations operating in the 3.7-4.2 GHz band to certify the accuracy of existing registration and license information and will collect additional information from space station licensees on their operations in the band to assist the Commission and commenters in developing a clearer understanding of how the band is currently being used.  The Commission will then use this information to evaluate the most efficient way to drive the deployment of mid-band spectrum for mobile services and more intensive fixed services.

The FCC said its Notice also proposes to add a mobile (except aeronautical mobile) allocation to all 500 megahertz in the band and seeks comment on various proposals for transitioning part or all of the band for flexible use, working up from 3.7 GHz, including market-based, auction, and alternative mechanisms.  The Notice also seeks comment on allowing more intensive point-to-multipoint fixed use in some portion of the band, on a shared basis, working down from 4.2 GHz and on how to define and protect incumbent users from harmful interference, and it seeks comment on service and technical rules that would enable efficient and intensive use by any new services in the band.

Corning cites a 22% rise in optical sales in Q3

In its Q3 financial report, Corning reported a year-over-year sales increase of 22% for Optical Communications. Sales exceeded $1 billion for the second consecutive quarter. Sales growth was driven by strong demand from both data center and carrier customers, and the acquisition of 3M’s Communication Markets Division. Net income was up 27% year over year, as capital investments yielded clear benefits.

The company said it saw increased customer commitments that support accelerated capacity expansion. Strong growth is expected to continue in the fourth quarter, as additional capacity ramps, and the company supplies large projects underway at multiple customers in both the carrier and data center businesses. Fourth quarter sales are expected to be up by a low-single digit percentage sequentially, resulting in year-over-year sales growth slightly better than the third quarter.

For full-year 2018, sales are expected to increase by a high-teens percentage over last year, with organic growth in the low teens and approximately $200 million in sales from the acquisition of 3M’s Communication Markets Division.

Corninng also cited share growth and said its optical business continued to progress faster than expected toward goal of $5 billion in annual sales by 2020.

Juniper posts Q3 revenue of $1,180 million, but sees slower cloud sales

Juniper Networks posted Q3 net revenues of $1,179.8 million, a decrease of 6.0% year-over-year, and a decrease of 2.0% sequentially. GAAP operating margin was 13.6%, a decrease from 18.4% in the third quarter of 2017, and an increase from 13.3% in the second quarter of 2018. Non-GAAP operating margin was 20.0%, a decrease from 23.5% in the third quarter of 2017, and an increase from 18.5% in the second quarter of 2018.

GAAP net income was $223.8 million, an increase of 35.0% year-over-year and an increase of 92.0% sequentially, resulting in diluted earnings per share of $0.64. Non-GAAP net income was $191.0 million, a decrease of 10.0% year-over-year and an increase of 12.0% sequentially, resulting in diluted earnings per share of $0.54.

"We reported better than expected Q3 results, as continued enterprise strength and better than expected service provider results more than offset weakness in the cloud," said Rami Rahim, chief executive officer, Juniper Networks. "While our Q4 outlook is being impacted by the pace of deployments at several cloud customers, we believe this is a temporary headwind and remain confident that we have the right products and strategy in place to grow the business in 2019."

"We delivered better than expected non-GAAP earnings during Q3, as gross margin exceeded the high-end of our forecast and operating expenses came in at the low-end of our outlook. We also completed our $750 million accelerated share repurchase in the period," said Ken Miller, chief financial officer, Juniper Networks. "While we believe we are making the investments needed to win in the market, we remain focused on capturing additional efficiencies and creating shareholder value."

Regarding its outlook, Juniper cited the slower pace of expected deployments by cloud customers for a likely year-over-year decline in revenues for Q4. The company has not seen any impact from Chinese tariffs but said customer buying behavior could be affected and gross margin could be slightly impacted.

Some highlights:

  • Routing product revenue: $496 million, down 15% year-over-year and up 1% sequentially, driven by Enterprise and Service Provider, partially offset by a decrease in Cloud. The MX product family declined year-over-year but grew sequentially. The PTX product family declined both year-over-year and sequentially.
  • Switching product revenue: $221 million, up 4% year-over-year and down 13% sequentially. While the EX product family grew year-over-year, the QFX product family slightly declined year-over-year due to the timing of deployments.
  • Security product revenue: $77 million, up 8% year-over-year and down 3% sequentially due to Enterprise, partially offset by an increase in Service Provider.
  • Service revenue: $385 million, down 1% year-over-year and up 2% sequentially. 


  • Cloud: $250 million, down 28% year-over-year and down 11% sequentially, due to lower routing and switching sales.
  • Service Provider: $544 million, down 6% year-over-year and up 4% sequentially. 
  • Enterprise: $386 million, up 15% year-over-year and down 4% sequentially.
