Facebook tests trans-Atlantic 700 Gbps wavelength with Infinera's ICE6

 Facebook achieved two significant optical transmission records during recent testing of Infinera's ICE6 optical engine over the MAREA trans-Atlantic cable system:

MAREA hero results over 6,640 km

  • 30 Tbps of total capacity on a single fiber pair
  • 700 Gbps data rate per wavelength
MAREA deployable results over 6,640 km:
  • 28 Tbps of total capacity on a single fiber pair
  • Up to 650 Gbps data rate per wavelength


The hero result is considered maximum performance because it offers no additional deployment margin.

The MAREA cable system, which spans 6,640 km from Bilbao to Virginia Beach, has been used by multiple vendors for testing state-of-the-art equipment and is considered the benchmark for testing because it was specifically optimized for maximum capacity per fiber pair. MAREA uses a low-loss optical fiber type based on a pure silica core. It also features short amplifier spacing of 56 km.

Infinera cited several factors for the record-breaking performance of its ICE6 engine in this trial, including the use of Nyquist subcarriers, the advantage of long code words for probablistic constellation shaping (PC), nonlinear algorithms and mitigation techniques (e.g., super-Gaussian distributions), as well as dynamic bandwidth allocation. 

In a blog post, Steve Grubb, Global Network Optical Architect, states "the higher data rate per wave, the better the cost per bit – and that includes the fact that we need fewer transponders that consume less rack space and less electrical power. The 28 Tb/s option with ICE6 reduces the network element count by 60% vs. the boxes previously required for 24 Tb/s…that’s a huge improvement, especially in cable landing stations where real estate and power are often at a premium."

Cisco's NCS 1004 platform tested over MAREA subsea cable

Cisco's NCS 1004 platform was successfully tested over MAREA, the 6,600 km subsea cable system connecting the United States to southern Europe (Virginia Beach, Virginia to Bilbao, Spain). Several channel capacity combinations were tested to maximize the performance and spectral efficiency on the cable. For the Virginia to Bilbao trial, 400G error-free performance was demonstrated; channels with record spectral efficiency of 6.445 b/s/Hz were achieved,...

A team of researchers from Infinera has achieved new benchmarks for efficiency for transatlantic fiber optic cables. By employing 16QAM modulation on the MAREA transatlantic cable, the researchers generated signal speeds topping out at 26.2 terabits per second, a 20 percent increase over what the cable designers originally thought feasible. By comparison, the most common way signals are modulated for MAREA today only reaches 9.5 terabits per second....

AWS to lease fiber pair on Marea's transatlantic cable

Amazon Web Services (AWS) signed an IRU agreement for the use of a fiber pair on MAREA, the transatlantic submarine cable partially owned by Telxius. MAREA is the highest capacity submarine cable in the world and provides the lowest latency route between the U.S. and Southern Europe. The route is further south than other transatlantic cables, with landing points in Virginia Beach and Sopelana, Spain. “We have developed a deep relationship with...

A field demonstration conducted by Acacia Communications, in collaboration with Microsoft and Facebook, achieved the first 400G single carrier DWDM transmission over the 6,600 km Marea submarine cable between Virginia Beach, Virginia and Bilbao, Spain. The transmission employed Acacia’s AC1200 coherent module, which is powered by its Pico digital signal processor.  Utilizing Acacia’s patented Fractional QAM modulation, the field demonstration...


IDC: Public cloud IT infrastructure revenue growth stays strong

Vendor revenue from sales of IT infrastructure products (server, enterprise storage, and Ethernet switch) for cloud environments, including public and private cloud, increased 9.4% year over year in the third quarter of 2020 (3Q20), according to the International Data Corporation (IDC) Worldwide Quarterly Cloud IT Infrastructure Tracker. Investments in traditional, non-cloud, IT infrastructure declined -8.3% year over year in 3Q20.

Some highlights:

  • Spending on public cloud IT infrastructure increased 13.1% year over year in 3Q20, reaching $13.3 billion. During the previous quarter spending on public cloud IT infrastructure exceeded non-cloud IT infrastructure spending for the first time ever, but non-cloud IT infrastructure spending was back on top in 3Q20 at $13.7 billion. 
  • IDC expects public cloud IT infrastructure spending to surpass non-cloud IT infrastructure spending again in the near future and expand its lead going forward.
  • Spending on private cloud infrastructure increased 0.6% year over year in 3Q20 to $5.0 billion with on-premises private clouds accounting for 63.2% of this amount.
  • IDC believes the hardware infrastructure market has reached a tipping point and cloud environments will continue to account for an increasingly greater share of overall spending. 
  • Within cloud deployment environments in 2020, compute platforms will remain the largest segment (49.1%) of spending, growing at 2.3% to $36.4 billion while storage platforms will be the fastest growing segment with spending increasing 27.4% to $29.2 billion, and the Ethernet switch segment will grow 4.0% year over year to $8.5 billion.
  • Spending on cloud IT infrastructure increased across most regions in 3Q20, with the highest annual growth rates in Canada (32.8%), China (29.4%), and Latin America (23.4%). Growth in the United States was 4.7%. Japan and Western Europe declined by -6.7% and -3.4%, respectively. In all regions except Canada and Japan, growth in public cloud infrastructure exceeded growth in private cloud IT.
  • Inspur, Huawei, and Lenovo had double-digit year-over-year growth while most other major vendors, including the ODM Direct group of vendors, had single-digit growth. Cisco was the only major vendor with a year-over-year decline.


IDC: PC sales rocket ahead at 26% growth rate

 Due to ongoing work-from-home and school-from-home trends during the pandemic, global sales of traditional PCs (inclusive of desktops, notebooks, and workstations) experienced a 26.1% year over year growth during Q4 2020 to 91.6 million units, according to preliminary results from the International Data Corporation (IDC) Worldwide Quarterly Personal Computing Device Tracker. The same category of devices grew 13.1% year over year for the full year 2020 with the catalysts being work from home, remote learning, and restored consumer demand.

"Every segment of the supply chain was stretched to its limits as production once again lagged behind demand during the quarter," said Jitesh Ubrani research manager for IDC's Mobile Device Trackers. "Not only were PC makers and ODMs dealing with component and production capacity shortages, but logistics remained an issue as vendors were forced to resort to air freight, upping costs at the expense of reducing delivery times."
