NTT and Tokyo Institute of Tech achieve 100 Gbps using terahertz band

NTT and Tokyo Institute of Technology have jointly developed an ultra high-speed IC for wireless front-end that operates on a terahertz frequency band, and in the 300 GHz band they have achieved a record 100 Gbps wireless transmission data rate.

The researchers implemented a mixer circuit that applied a unique proprietary high isolation design technology with an Indium phosphide high electron mobility transistor (InP-HEMT). NTT said this process enlarged the transmission bandwidth, which is a problem in the conventional 300 GHz band wireless front end. It also improved the signal-to-noise ratio (SNR). In addition, using this we realized a 300 GHz band wireless front-end module, and we achieved wireless transmission of 100 Gbps (gigabits per second).

NTT said future work will extend to multiple carriers by making use of the wide frequency band of 300 GHz band, and using spatial multiplexing technology such as MIMO and OAM. The researchers hope to produce an ultra high-speed IC that enables wireless transmission of 400 Gbos.

Deutsche Telekom extends broadband rollout

Deutsche Telekom confirmed plans to lay 60,000 kilometers of optical fiber in 2018. This compares to 40,000 kilometers laid in 2017.

Telekom's full fiber-optic network now measures 455,000 kilometers -- the largest in Europe. It would wrap around the Earth ten times.

Telekom calculates that it costs between 50,000 and 150,000 euros to lay a kilometer of optical fiber cable.

Deutsche Telekom kicked off a fiber-optic build-out in the port area of the Free and Hanseatic City of Hamburg.

The rollout will bring fiber connections to an estimated 1,000 businesses in the area. The effort will involve laying more than 80 kilometers of fiber-optical cabling and installing 28 distribution cabinets.

“Among the federal states, Hamburg is already taking on a leading role in the provision with digital infrastructure. Fiber-optic connectivity is no
longer just a vision for our city: it’s a reality. The on-going expansion needs to make quick progress. Business parks and the Port area are particularly important in this effort to ensure that Hamburg remains an ultra-modern, highly future-ready business and industrial location. We welcome the fact that Deutsche Telekom too is driving on with the fiber-optic build-out in Hamburg,” says Frank Horch, the Hanseatic City’s minister for economy, transport and innovation.

Deutsche Telekom also noted that more than 832,000 households across Germany are now eligible for 100 Mbps service thanks to its expanded use of vectoring technology over its copper network.

“Carriers and service providers are now realizing that they need to position themselves to meet the challenge of increased capabilities and capacities for themselves, as well as their end users. NJFX is helping to make this possible,” confirmed Gil Santaliz, founder and CEO of NJFX.

Tintri teeters at edge on insolvency, less than 1 year after IPO

Less than one year after completing its IPO, Tintri (NASDAQ: TNTR), which specializes in enterprise cloud platforms, reported that it is currently in breach of certain covenants under its credit facilities and likely does not have sufficient liquidity to continue its operations beyond June 30, 2018.

The company said it continues to evaluate its strategic options, including a sale of the company.

Q1 revenue is expected to be approximately $22 million and GAAP net loss per share is expected to be approximately ($1.14) for its fiscal quarter ended on April 30, 2018.

The closing bid price of the company’s common stock on the Nasdaq Stock Market has been less than $1.00 per share since May 22, 2018.

Tintri warned that even if it able to secure a strategic transaction before the end of the month, there is a significant possibility that the company may file for bankruptcy protection, which could result in a complete loss of shareholders’ investment.

Tintri offers Lego-like Enterprise Cloud Amidst Fierce Competition


Tintri, a networking start-up from Silicon Valley, made its initial public offering (IPO) on June 30,2017 and its shares are now trading on NASDAQ under the symbol 'TNTR'. The IPO raised approximately $60 million for the Mountain View, California-based company – a lukewarm Wall Street response considering earlier speculation that the shares might debut in the range of $10.50 to $12.50. Many expected the IPO to occur at the start of last week and at the higher price range. It was not clear why the IPO was delayed by a few days, but the lower price must have caused consternation for early investors and employees. Post IPO, Tintri, which means 'lightning' in the Irish language, currently has a market capitalisation value of about $225 million.

Tintri was founded in 2008 by Kieran Hearty, who had previously led engineering at VMware, and Mark Grittier, who had previously worked on software engineering at Sun Microsystems. The first products were introduced nearly 3 years later in March 2011. In August 2015, Tintri raised a $125 million Series F funding round led by Silver Lake Craftwork and included existing investors Insight Venture Partners, Light speed Ventures, Menlo Ventures and NEA. In December 2016, Charles Giancarlo, the former CTO of Cisco Systems, joined the Tintri board.
Tintri prides itself of having developed an enterprise cloud platform with a 'Lego-like' design that allows for every storage action at the individual virtual machine level. The value proposition is simple: scale the enterprise cloud from terabytes of storage to multiple petabytes as efficiently as possible. The Tintri CONNECT web services architecture use the 'Lego' building-block approach predicated on REST APIs and VM and container level abstraction. The frameworks runs applications on resource pools that span VMware, Citrix,Microsoft and OpenStack. This supports a DevOps model, where resource can be spun up or torn down on-demand, including via automated bots or modern interfaces such as Slack or Amazon's Alexa. To deliver this, Tintri's platform integrates cloud management software, web services and a range of all-flash storage systems.

A key ingredient is a virtualisation-aware file system that allows an organisation to view, manage and analyse application performance and quality of service. In a sense, it enables a private version of a public cloud. Use cases include server virtualisation, virtual desktop infrastructure, or VDI, disaster recovery and data protection, and development operations, or DevOps. Tintri says it has an advantage because innovation in storage has lagged and lacked granular level operation at the VM and container level.

Huawei announces 5G-oriented Discrete Spectrum Aggregation

Huawei released its 4.5G-based, 5G-oriented eLTE Discrete Spectrum Aggregation (eLTE-DSA) for energy utilities

Huawei said traditional narrowband solutions based on VHF (30 MHz to 300 MHz) and UHF (300 MHz to 3000 MHz) bands are flawed with low data rates, long latency, small capacity, which means they are unable to meet the demand for sustaining IoE growth.

Huawei has designed the eLTE-DSA solution to overcome the obstacles of traditional narrowband solutions and support IoE developments through leading advantages in Wireless Communications developed over the years.

By aggregating discrete narrowband resources, Huawei said its solution achieves access with an end-to-end delay as low as 20 ms and a huge capacity of up to 4,000 users in a single cell. The transmission rates reach kbpss to Mbps and the module power consumption is as low as 0.15W. This solution noticeably improves spectrum efficiency, capacity and performance of the networks, enabling the energy industry to move seamlessly towards 5G-oriented IoE. 

Eric Sun, President of Huawei Enterprise Wireless Business, said: "Going wireless will provide the foundation for the Internet of Energy. 4.5G technology will enable the Internet of Things, and 5G will accelerate the connection of people and things. With leading technological advantages in 4.5G and 5G, Huawei has successfully developed the 4.5G-based, 5G-oriented eLTE-DSA solution."
