Australian researchers achieve 44.2 Tbps from a single light source.

Researchers from Monash, Swinburne and RMIT universities in Australia have tested a single light source delivering 44.2 Tbps. The research, which is published in the journal Nature Communications, tested a device that replaces 80 lasers with one single piece of equipment known as a micro-comb.

The ultra-high data transmission occurred over 75 km of standard optical fibre using the single integrated chip source over the C-band at 1550 nm with a spectral efficiency of 10.4 bits s−1 Hz−1. Micro-comb spacing of 48.9 GHz enabled the use of 64 QAM - quadrature amplitude modulated.

Professor Moss, Director of the Optical Sciences Centre at Swinburne, says: “In the 10 years since I co-invented micro-comb chips, they have become an enormously important field of research. “It is truly exciting to see their capability in ultra-high bandwidth fibre optic telecommunications coming to fruition. This work represents a world-record for bandwidth down a single optical fibre from a single chip source, and represents an enormous breakthrough for part of the network which does the heaviest lifting. Micro-combs offer enormous promise for us to meet the world’s insatiable demand for bandwidth.”

Crehan: Server-class Ethernet adapter market up 30% YoY in Q1

Shipments of total server-class Ethernet adapters increased more than thirty percent year-on-year in the first quarter of 2020, according to a recent report from Crehan Research. This increase is the largest the market has had in over eight years – see accompanying figure – and resulted in record shipments. In correlation with these record shipments, server-class Ethernet adapter revenue also had a record quarter and posted an even higher growth rate.

“Data center operators added server networking capacity at record levels to ensure delivery of the digital-based services that have become so important as a result of the COVID-19 pandemic,” said Seamus Crehan, president of Crehan Research. “These services include telemedicine and food and merchandise delivery, as well as the enablement of working, schooling and entertainment from home. On top of this, data center operators had to ensure the continuity of existing bandwidth-hungry applications and initiatives in a very challenging and disrupted supply-chain environment.”

Other noteworthy results from Crehan’s Server-Class Ethernet Adapter report include:

  • The strength in the server-class Ethernet adapter market was broad-based with all speeds – from one gigabit Ethernet (GbE) up to 200GbE – experiencing shipment increases. However, 25GbE, 50GbE, and 100GbE growth was particularly strong during the quarter with combined shipments more than doubling year-over-year.
  • Intel accounted for the majority of total server-class Ethernet adapter shipment volumes and shipment growth.
  • Nvidia (Mellanox) comprised the majority share of shipment speeds of 25GbE-and-greater and drove most of the robust growth in this segment.
  • Marvell saw its 25GbE QLogic-based adapter shipments more than double year-over-year, as a result of strong blade server adoption of its FastLinQ products.
  • Vendor-built SmartNIC shipments more than tripled year-over-year but still comprised a relatively small portion of total server-class Ethernet adapter volumes. Broadcom’s Stingray product drove most of this growth.
“Given the migration to higher speed server-class Ethernet adapter connections, the bandwidth increase in the quarter was even higher than the shipment increase, which further accelerated a recent inflection in server networking bandwidth growth,” Crehan said.

Alibaba Cloud grew 58% YoY in March quarter

Alibaba's cloud division recorded sales of RMB 12.217 billion (US$1.725 billion) for its most recent quarter, up 58% YoY.  The growth was primarily driven by increased revenue contributions from both its public cloud and hybrid cloud businesses. Adjusted EBITA was a loss of RMB179 million (US$25 million).

Huawei develops CableFree antenna design for 5G masts

Huawei has developed a "CableFree" antenna design for 5G base stations that significantly reduces the internal complexity for multi-band services.

Huawei's new design features cable-free feeding and integrated phase shifters. This produces a distinct increase in antenna integration, tangibly improving antenna performance.

Highlights:

  1. Exceptional high-band coverage for 5G. CableFree improves antenna radiation efficiency by approximately 20%, boosting high-quality coverage of the 5G era.
  2. Higher output power to facilitate 5G multi-band and multi-channel applications. 5G is designed to meet high-capacity and high-speed requirements, and this highlights the necessity of introducing new spectrum and deploying high-order MIMO technology. To adapt to this trend, antennas must accommodate a high power of up to 1 kW, far above 500 to 600 watts of previous radio access technologies. CableFree increases the antenna power capacity by more than 80%, meeting the requirements for higher output power in the 5G era.
  3. Reduced antenna weight to facilitate installation. A higher level of antenna component integration offers an effective approach to reduce antenna weight. With CableFree, a six-band antenna can be 10 kg lighter. The weight of multi-band antennas can be kept below 50 kg. As a result, a crane is not required during installation, simplifying installation and reducing cost.
  4. Better PIM performance. PIM is short for passive intermodulation, reflecting signal interaction at the junction of two metal mechanical components of antennas. CableFree reduces screws and soldering points in antennas by 80%, reducing PIM risks while also ensuring long-term PIM stability. The resulting novel architecture and process further improve production automation and consistency among batches.

To date, CableFree has been successfully applied to Huawei's Munich Pro, Golden Mini, and London Pro series antennas, as well as 32T32R Massive MIMO products, helping customers quickly deploy high-quality 5G networks.


PAWR Project to test AI-Driven Spectrum Sharing

The Platforms for Advanced Wireless Research (PAWR) Project Office, led by US Ignite and Northeastern University, announces $2.7 million in new funding awarded by the U.S. Department of Defense for development work on advanced spectrum sharing technologies. 

The PAWR program will perform spectrum sharing tests on a live 5G-NR network at the POWDER wireless testbed site in Salt Lake City, Utah. The researchers hope to demonstrated how two mobile operators can occupy spectrum in the same CBRS channel autonomously using AI.

PAWR is funded by the National Science Foundation and a consortium of 35 industry partners.

“When we started the PAWR program to develop and deploy four city-scale wireless testbeds across the country, it was with the intention of creating shared infrastructure to enable new research into advanced communications network technologies,” said Joe Kochan, Principal Investigator and Project Director for the PAWR Project Office. “We’re gratified to be able to support the DOD’s mission today to further network performance with greater spectrum sharing capabilities in the transition to 5G and beyond.”
