Infinera and DANTE Demo Single-Card Terabit Super-Channel

Infinera and DANTE, the European advanced technology research network organization, successfully demonstrated a single card terabit super-channel on an active segment of GÉANT's production network between Budapest, Hungary and Bratislava, Slovak Republic.

The demonstration showed for the first time how a single photonic integrated circuit (PIC) can enable more than a terabit of super-channel coherent capacity from a single line card with a single fiber connector.

Infinera said the demonstration illustrated how the single card could plug into the existing line card slot of the Infinera DTN-X packet optical networking platform, which will be able to upgrade service to 1.2 Tb/s per slot in the future with a total of 12 Tb/s of non-blocking switching capacity in a single rack. This design is intended to provide forward-scale to support up to twelve 100 GbE interfaces or three of the emerging 400 GbE per 1.2Tb/s slot in the future, and the DTN-X will be able to support up to ten of these slots per chassis. In addition to the 12 Tb/s in a single bay, the DTN-X platform is designed to scale up to 240 Tb/s of non-blocking capacity managed as a single large switch.

"This is not only a single line card super-channel -- it is also a single chip super-channel," said Geoff Bennett, Director of Solutions and Technology at Infinera. "Large scale PIC technology is fundamental to making terabit scale super-channels a practical reality. The small footprint of the terabit scale PIC means we will be able to more than double the capacity of our line cards and our DTN-X chassis in the same rack space; and for all of the DTN-X customers around the world that means they can more easily scale to meet the ever-growing demand from the Internet."

"This is a great example of how the GÉANT network facilitates the innovation of new networking technologies, helping to shape the Internet of today and tomorrow," said Michael Enrico, CTO of DANTE. "This prototype service from Infinera will help us to continue to support the ever growing needs of our NREN (National Research and Education Network) partners and the research and education communities we all serve."

South Africa's MTN Tests 2.4 Tbps Wavelength with Huawei

South Africa-based MTN has conducted a live trial of Huawei's Transport Software-Defined Networking (SDN) and 2.4 Tbps wavelength-division multiplexing (WDM) system.

The ultra-fast single-channel 2.4 Tbps field trial took place on MTN’s national fibre backbone network in South Africa. In the first scenario, 2.4 Tbps with 16QAM (Quadrature Amplitude Modulation) was achieved over a transmission distance exceeding 300 km. In the second scenario, 2 Tbps with QPSK was achieved over a transmission distance of 1031 km.

Huawei described the system as the biggest in terms of capacity tested to date. In addition to the large system capacity, the "world’s first" transport SDN new features were also tested. Huawei Transport SDN solutions, using physical network modeling and resource abstraction, have realized transmission pipe virtualization. These advances allow traditional communication technology networks to be "IT-like". This trial successfully demonstrated SDN features such as Bandwidth on Demand (BoD), Virtual Transport Service (VTS) and Automatic O&M functions.

Mr. Navi Naidoo, Group Technology Officer, MTN, said: "With this successful field trial, we have demonstrated our commitment to digital innovation. MTN continues to invest in future-proof transport networks to realize world class technologies, not only to our existing markets, but to extend our technology offerings globally. We believe that networks such as cloud computing, streaming media and mobile broadband must be scalable, intelligent and flexible. To this end, Huawei's next generation optical evolution concept 'SDN-based flex optical network' properly fits our requirements."

Mr. Zha Jun, President of Huawei's Fixed Network Business Unit, said: "Huawei will maintain cooperation and joint innovation with MTN, and continue to promote the commercialization process of SDN and ultra-high speed optical transmission technology, in order to jointly meet the challenges of a digital future.

Coriant and Allied Fiber Test 1 Terabit Super-Channel

Coriant and Allied Fiber successfully transmitted a 1 Terabit-per-second (Tbps) super-channel over a 1,700 km fiber optic ring connecting West Palm Beach to Jacksonville, Florida.

The terabit field trial was conducted on Allied Fiber’s Southeast Florida segment using the commercially available Coriant hiT 7300 Multi-Haul Transport Platform and pre-commercial software, over Allied Fiber's new Corning fiber. The trial demonstrated 1 Tbps super-channel transmission in a 368.7 gigahertz (GHz) grid over 1,700 km. In addition, it showed a greater than 35 percent improvement in spectral efficiency which significantly increases the capacity of the system compared to conventional fixed grid technology.


The trial also demonstrated the flexible allocation of the 1 Tbps super-channel by placing it in three separate locations within the C-band, thus maximizing the usability of existing fiber resources.

Coriant said this capability comes with an improved spectral efficiency of 3.4 bits per second per Hertz (b/s/Hz) and provides a maximum fiber capacity of 13 Tbps over a distance of 1,700 km on field-installed fiber while using commercial-grade equipment.

"We are pleased to team with Allied Fiber to demonstrate the value that next-generation optical networking technologies can bring to broadband users," said Pat DiPietro, CEO, Coriant. "We are committed to helping our partners like Allied Fiber meet the capacity requirements of residential and business end-user services with systems capable of seamless and efficient scalability to 1 Terabit per channel and beyond."

"We are excited with the results of the trial with Coriant on our network-neutral infrastructure," said Hunter Newby, CEO of Allied Fiber. "It highlights how our new Corning SMF 28e+ fiber has performed carrying 1 Terabit transmission which should be encouraging news for all network operators looking to light their own transport route both for the capabilities of the technology and for the availability of the long-haul dark fiber to run it on."

Allied Fiber, which was founded in 2008, offers a combination of long-haul and multi-access point, short-haul fiber coupled with its own colocation facilities that provide control of the underlying physical assets to its network operator customers.

Huawei Launches 1T WDM Line Card

Huawei launched the world's first 1T WDM line card.

The line card delivers 800-km transmission based on common G.652 fibers and erbium-doped fiber amplifiers (EDFAs), but without regeneration. It can encapsulate client signals of any rate into an OTN-based 1 Tbps channel for transmission.

A demonstration was shown at the Next Generation Optical Networking Forum last week using Huawei's flagship OSN 9800 platform.

Huawei said its line card uses Optical Digital Signal Processing (oDSP) algorithm for processing high-speed signals. Switching between short-haul metro mode (ultra-high-capacity transmission) and ultra-long-haul backbone mode (ultra-long-haul transmission) can be implemented through software-based modulation scheme reconfiguration. The short-haul metro mode reaches a capacity of more than 20 Tbit/s per fiber, nearly triple that of current mainstream commercial 100G systems. The ultra-long-haul backbone mode supports more than 10 Tbit/s transmission per fiber over a distance of 3,000 km.

Huawei noted that it has deployed over 200 commercial 100G networks worldwide to date.

http://pr.huawei.com/en/news/hw-346706-1twdm.htm#.U7F1PfldVF4


  • In 2013, Huawei demonstrated a 40T Wavelength Division Multiplexing (WDM) prototype at the OFC/NFOEC 2013 event in Anaheim, California. The prototype supports simultaneous transmission of 20 C-band optical channels running at 2 Tbps, providing an industry-leading capacity of up to 40 Tbps per fiber. Huawei cited three innovations in its platform:
    The combined use of Electrical Orthogonal Frequency Division Multiplexing (eOFDM) and frequency-domain Hybrid Quadrature Amplitude Modulation (QAM) technologies substantially improve spectrum efficiency to 10 bit/s/Hz.

    The combined use of Flex-Optical Digital Signal Processing (Flex ODSP) and Hybrid Soft-/Hard-Decision Multi-level Coding (HMLC) technologies extend the transmission distance to beyond 1,000 km over common single-mode fiber and Erbium-Doped Fiber Amplifiers (EDFAs).

    Software-implemented transceiver technology allows optical modulation formats such as Quadrature Phase-Shift Keying (QPSK), 16QAM, 32QAM, and 64QAM to be adjusted or combined, achieving a configurable transmission rate and distance for each service. As a result, dynamic service needs in varied scenarios can be easily met.

  • In 2012, Huawei completed a 2 Tbps WDM field trial with Vodafone, achieving up to 3,325 km transmission for 2 Tbps signals. The 40T WDM prototype is another major breakthrough in high-speed transmission proving current commercial optical networks will be ready for the upcoming flood of digital traffic.

Tera Santa Consortium Demos 1 Tbps with ECI, Finisar, Technion

ECI Telecom, Finisar, MultiPhy, and the Technion Israel Institute of Technology have successfully demonstrated 1Tb/s transceiver transmission with the Tera Santa Consortium.

In the trial, the consortium transported non-regenerated 1Tb/s coherent super channel signal through the German Research Network - Deutsches Forschungsnetz e.V. (DFN-Verein) optical network. The trial, which took place at the Technische Universität Dresden, ran over DFN’s live X-WiN network, and used the 1Tb/s transceiver developed by the Tera Santa Consortium, as part of its research on 1Tb/s adaptive coherent channel behavior. It demonstrates the advanced capabilities of the Tera Santa 1T transmission system and technologies in compensating for channel impairments and chromatic dispersion utilizing advanced QAM16 and OFDM modulations and algorithms.

The Tera Santa Consortium was established in 2011 as an initiative of the Israeli Chief Scientist Office in the Ministry of Economy, through the Magnet Program which promotes cutting-edge technologies for the future. The Tera Santa Consortium brought together Israeli technology companies and universities to develop the world’s first Orthogonal Frequency Division Multiplexing (OFDM)-based optical transceiver. The members of the consortium are ECI Telecom, Finisar Corporation, MultiPhy, Cello, Civcom, Bezeq International, the Technion Israel Institute of Technology, Ben-Gurion University, the Hebrew University in Jerusalem, Bar-Ilan University and Tel-Aviv University.

For the trial, ECI deployed its Apollo family of packet-optical transport solution across DFN’s X-WiN’s network in 2012, and has since upgraded it to support the delivery of 100G services

Finisar demonstrated the software-defined 1 Terabit optical transceiver, which hosted the different algorithms developed by the consortium, in an end-to-end transceiver platform utilizing Finisar Flexgrid™ - WSS used to add/drop the 200GHz super channel signal. The OFDM algorithms were developed by both MultiPhy (128 OFDM carriers) and the Technion (1024 OFDM carriers), using two different implementation approaches.
"ECI and our technology partners Finisar, MultiPhy and the Technion, members of the Tera-Santa consortium, demonstrated the power of 1-terabit optical link coherent technology. With such high transmission rates, DFN can exponentially increase its network capacity and provide its users better and more cost effective services," stated Shai Stein, CTO, ECI Telecom and Consortium Chairman.

OVH, the leading web hosting in Europe with more than 140,000 physical servers online, will deploy the Infinera DTN-X platform to interconnect its data centers via its pan-European network. The OVH pan-Eureopan network links data centers throughout 10 major European cities in seven countries.

Infinera said its platform was selected for its ability to provision large amounts of bandwidth very quickly.  The Infinera DTN-X enables long-haul 500 Gbps super-channels across the optical transmission network.  I also offers integrated OTN switching, enabling efficient utilization of long-haul capacity while at the same time enabling OVH to rapidly deploy large amounts of optical bandwidth for customer services.
