Fujitsu, NTT and NEC Target 400G Coherent Optical Transmission

Fujitsu, NTT and NEC are jointly developing 400 Gbps/channel-class digital coherent optical transmissions technology.

The companies have undertaken a joint R&D project that aims to leverage the technological capabilities that have enabled the commercialization of 100Gbps-class optical transmission. The R&D initiative was commissioned and is sponsored by Japan's Ministry of Internal Affairs and Communications (MIC) as part of the "Research and Development Project for the Ultra-high Speed and Green Photonic Networks".

Specifically, Fujitsu, NTT and NEC have pursued R&D on 100Gbps-class digital coherent optical communications technology as part of the MIC's "Research and Development on High Speed Optical Transport System Technologies" program (2009) and "Research and Development on Ultra-high Speed Optical Edge Node Technologies" program (2010-2011).

As a result of the previous research, a digital coherent DSP-LSI was commercialized in 2012 and is now being being deployed by each company. The new initiative will accelerate this work for 400Gbps-class optical transmissions.

The joint research project is targeting dual-polarization quadrature phase shift keying (DP-QPSK)(3), which is currently in use for 100Gbps transmissions, together with dual-polarization 16 quadrature amplitude modulation (DP-16QAM), which takes advantage of an even greater number of quadrature carriers.

The companies said that by incorporating these modulation techniques into a high-density 60-channel fiber, the technology will be able to bring about optical networks capable of 24 Tbps/fiber.  The goal will require development of the first compensation technology for nonlinear optical effects within an optical fiber.  This is the primary limiting factor standing in the way of long-distance transmission of multiple quadrature modulated signals. When employed together with enhanced-performance versions of existing compensation technologies for chromatic dispersion and polarization mode dispersion, the new technology will achieve longer transmission distances.

The companies will pursue the implementation of adaptive modulation/demodulation technology that can employ a host of modulation techniques depending on the transmission route using a single hardware device, thereby leading to the construction of flexible network


FCC Approves Changes to AWS-4 Spectrum Requirements

The FCC voted unanimously to approve an order that frees up 40 MHz of underutilized satellite spectrum for land-based mobile broadband, including 4G LTE.  The decision removes regulatory barriers that limited this spectrum to satellite use.

The FCC said its action balances technical requirements and will unlock value in both the AWS-4 band and the 10 MHz H Block.

DISH issued a statement supporting the action.  “The FCC has removed outdated regulations and granted terrestrial flexibility for most of the AWS-4 band. We appreciate the hard work and focus of the FCC and its staff throughout this process. The Commission has taken an important step toward facilitating wireless competition and innovation, and fulfilling the goals of the National Broadband Plan. Following a more thorough review of the order and its technical details, DISH will consider its strategic options and the optimal approach to put this spectrum to use for the benefit of consumers,” stated Jeff Blum, DISH senior vice president and deputy general counsel.

The FCC also unanimously approved a proposal setting the stage for an auction of the H
Block in 2013. Proceeds from this auction will help fund a nationwide Public Safety Network for first responders and reduce the deficit.


Berlin's ECIX Internet Exchange Upgrades to 40 GbE Trunks

Berlin's ECIX, the second-largest German Internet exchange, has upgraded its fabric with Extreme Networks' BlackDiamond X8 switch and is now offering 40 GbE connections to its members.

The European Commercial Internet Exchange (ECIX), with locations in Dusseldorf, Berlin and Hamburg, serves more than 120 carriers and Internet service providers. The BlackDiamond X8 switching systems will be implemented in all of its locations.

ECIX currently operates 204 active physical ports, 52 of which are 10 gigabit ports. Its peak bandwidth is greater than 100 Gbps. At the moment 191 autonomous systems from carriers and internet service providers are connected.

Extreme Networks BlackDiamond X8 switch can handles 20-Terabit non-blocking traffic with up to 768 ports for 10 GbE or 192 ports for 40 GbE in a 14.5 RU chassis or 1/3 rack.

"Availability of the BlackDiamond X8 came for us at precisely the right time as we are upgrading our performance," said Stefan Wahl, CEO of Peering GmbH and Managing Director of ECIX. "For our members, price and availability are very important factors. With its high port density, extremely competitive price and the low energy consumption, the system offers comparatively reasonable costs per port which we can then pass on to our customers."


  • In September, DE-CIX, the Internet exchange located in Frankfurt am Main (Germany), hit a new data throughput record last week  as Internet traffic across its switching fabric exceeded the 2 Tbps (terabits per second) mark for the first time.

    DE-CIX currently servers over 480 Internet service providers from over 50 countries.  At DE-CIX, more than 12 petabytes of data are exchanged per day.

    "Although the traffic peak of over 2 Tbps marks a new high,” says Harald A. Summa, CEO at DE-CIX Management GmbH, “we do not see an end to data traffic growth on the horizon. We assume that Internet traffic will continue to grow by about 80 per cent per year in the future”. At DE-CIX, HD-TV, video and multimedia content, online gaming and cloud computing are considered the main drivers behind the continuing increase in data traffic."

    The switching fabric of DE-CIX has the potential to scale to 40 Tbps, according to Arnold Nipper, Technical Manager at DE-CIX. "The DE-CIX peering infrastructurehas a star-shaped topology and is spread out over a total of twelve data centers operated by different providers in the Frankfurt metropolitan area.  The center of the DE-CIX peering star is composed of two redundant core switch clusters, one active and the other in hot standby mode.  If there are any problems with the operative switch cluster, data traffic is immediately and automatically, in other words within milliseconds, routed to the other switch cluster so that data streams can flow continually without interruption.  The central core switch clusters are redundantly connected to 14 other switches which are in turn connected to the ISPs."http://www.de-cix.net/about/statistics/ 

  • Equipment deployed in the DE-CIX distributed fabric includes Force10 Networks' Terascale platform.

Defense Dept Data Center Tries Direct-to-Chip Water Cooling

The U.S. Department of Defense (DoD) will retrofit one of its data centers with direct-to-chip liquid-cooling technology from Asetek.

The $2 million project will use Asetek's RackCDU (Rack Coolant Distribution Unit) technology, which is a hot water, direct-to-chip, data center liquid cooling system that removes heat from CPUs, GPUs, memory modules and other hot spots within servers.  No power is used to chill the water.  The direct-to-chip cooling loops replace existing air heat sinks, with tubes exiting through an unused PCIe slot in the server chassis.

Johnson Controls Federal Systems is the installer and integrator for the project.

Asetek claims a more than 50% cooling cost savings.

“The Department of Defense has become very serious about improving data center efficiency, and they are seeking new approaches to address this mission-critical problem,” said Andre Eriksen, Asetek’s CEO and founder. “Hot water direct-to-chip liquid-cooling is a powerful approach that can capture more than 80% of the heat generated by a data center and remove it from the building, where it can be cooled for free by ambient air or even reused for building heating and hot water. No power what so ever goes in to actively chilling the water.”


  • Asetek is headquartered in San Jose, California with offices in Denmark, China and Taiwan. The company was founded in 2000.
