Ciena Adds Long-Haul Capability to Waveserver DCI System

Ciena announced long haul capabilities for its Waveserver data center interconnect (DCI) platform/

The Waveserver leverages Ciena’s WaveLogic 3 Extreme chipset to provide 200 Gbps wavelengths at greater than 1,000 km distances and 100 Gbps wavelengths in excess of 10,000 km.

Waveserver is in customer trials and will be generally available in October 2015. Long-haul optics capabilities on the platform are expected to be available in the first quarter of 2016.

“A direct response to customer demand on the heels of our Waveserver introduction earlier this year, the enhancements that support DCI for any distance deliver another industry first in coherent technology and overcome the DCI capacity and distance trade-off paradigm. Competing platforms lack the high-performance of our WaveLogic Extreme chips and its breadth of advanced network monitoring and optimization capabilities,” stated Francois Locoh-Donou, Senior Vice President, Global Products Group, Ciena.

UCSD Cites Major Advancement in Optical Transmission

Researchers at the University of California - San Diego announced a breakthrough in photonic transmission with the potential to increase the efficiency of long haul fiber optic cables.

Research published in the June 26 issue of the journal Science describes a solution to a long-standing roadblock to increasing data transmission rates in optical fiber: beyond a threshold power level, additional power increases irreparably distort the information travelling in the fiber optic cable.

“Today’s fiber optic systems are a little like quicksand. With quicksand, the more you struggle, the faster you sink. With fiber optics, after a certain point, the more power you add to the signal, the more distortion you get, in effect preventing a longer reach. Our approach removes this power limit, which in turn extends how far signals can travel in optical fiber without needing a repeater,” said Nikola Alic, a research scientist from the Qualcomm Institute, the corresponding author on the Science paper and a principal of the experimental effort.

In lab experiments, the researchers at UC San Diego demonstrated transmission over a distance of 12,000 kilometers with standard amplifiers and no repeaters (electronic regenerators). The breakthrough relies on wideband “frequency combs” that the researchers developed. The frequency comb described in this paper ensures that the signal distortions — called the “crosstalk” — that arises between bundled streams of information travelling long distances through the optical fiber are predictable, and therefore, reversible at the receiving end of the fiber.

“Crosstalk between communication channels within a fiber optic cable obeys fixed physical laws. It’s not random. We now have a better understanding of the physics of the crosstalk. In this study, we present a method for leveraging the crosstalk to remove the power barrier for optical fiber,” explained Stojan Radic, a professor in the Department of Electrical and Computer Engineering at UC San Diego and the senior author on the Science paper. “Our approach conditions the information before it is even sent, so the receiver is free of crosstalk caused by the Kerr effect.”

Coriant Supplies 100G for UNINETT's Arctic Optical Network

UNINETT, a non-profit provider of telecom and data network connections to Norwegian universities and research institutions, selected Coriant to build a new 100G-capable subsea optical transport infrastructure connecting Ny-Ålesund and Longyearbyen on the Svalbard archipelago. The network will enable UNINETT to scale optical transmission capacity and meet the low latency connectivity requirements of demanding, high-bandwidth scientific research and education traffic and applications.

The deployment uses the Coriant hiT 7300 Multi-Haul Transport Platform and the Coriant Transport Network Management System (TNMS), serving as Submarine Line Terminal Equipment (SLTE).  The Coriant hiT 7300 LH/ULH platform will provide UNINETT with coherent 100G connectivity between Ny-Ålesund and Longyearbyen in a DWDM subsea application spanning approximately 260 kilometers.

The northernmost civilian year-round settlement in the world, Ny-Ålesund is an important international research community that hosts a broad range of life, earth, and environmental scientists. Eleven institutions from ten countries have established permanent research stations in Ny-Ålesund, and an increase in research activities, including plans for a new astronomical research observatory, is one of the primary drivers behind the need for higher network capacities. Real-time and near-real time astronomy data transmission is one example of the types of research and education applications requiring reliable, high-speed connectivity.

“High-speed global collaboration and real-time exchange of media-rich data and applications are critical to research and educational institutions, and serve as the life blood of research communities like Ny-Ålesund,” said Vidar Faltinsen, Chief Technology Officer, UNINETT. “In order help us achieve our goal of bringing our customers state-of-the art broadband communications, we needed a proven technology partner that could deliver a highly reliable and flexible DWDM solution, with the service expertise to support network deployment and service commissioning in Svalbard’s particularly harsh environment. Coriant proved the ideal partner on all fronts.”

“Coriant has a wealth of experience in providing robust and reliable optical transport solutions for hybrid subsea and terrestrial networks,” said Uwe Fischer, Chief Technology Officer, Coriant. “We continue to build our industry leadership on superior photonic layer performance, stability, and scalability, with proven features such as active power transient management and integrated high-density LH/ULH ROADMs that ensure the high-availability required by UNINETT’s customers.”

Facebook Deploys Infinera for Multi-Terabit European Network

Facebook has deployed an Infinera Intelligent Transport Network  to light the world's longest terrestrial optical network route, spanning 3,998 kilometers without any regeneration.

The network, which is capable of delivering up to eight terabits per second (Tbps) of data transmission capacity, stretches from Facebook's data center in Lulea, Sweden across major hubs throughout Europe. Facebook deployed the Infinera portfolio of products, which includes the DTN-X platform, to connect these hubs, harnessing Infinera’s unique FlexCoherent solution to deliver terabits of capacity on a single fiber across the continent.

Infinera said its DTN-X platform enables Facebook's European network to deliver 100G coherent transmission via 500 Gbps super-channels, with the ability to support 1.2 Tbps super-channels in the future. The high capacity super-channels are enabled by 500 Gb/s photonic integrated circuits (PICs) developed and fabricated by Infinera – the only supplier providing 500 Gb/s of transmission capacity from a single line card. PICs enable the DTN-X platform to integrate wavelength division multiplexing super-channel transmission with up to 12 Tbps of non-blocking optical transport network switching, providing seamless scaling as traffic requirements grow in the future. The DTN-X also features SDN-ready application programming interfaces that enable network programmability and automation of network operations to reduce both operational cost and service delivery times while facilitating new services.

"The Infinera Intelligent Transport Network makes it easy for us to rapidly grow network capacity while keeping operations simple,” said Niclas Comstedt, Director of Network Engineering at Facebook. “Once the equipment is in place we are able to turn up as many terabits as we need."

“I’ve worked closely with service providers around the world to test and deploy ultra-long-haul optical transport systems for over a decade,” said Steve Grubb, Fellow at Infinera. “The route we are announcing with Facebook is delivering multi-terabit capacity today and I believe this is the world’s longest 8 Tb/s capable route in production.”

"Facebook's deployment of the Infinera Intelligent Transport Network underscores the value Infinera brings to Internet content providers and datacenter operators around the world," said Tom Fallon, Infinera CEO. "Facebook is a classic example of how leading Internet content providers are building global networks that interconnect their datacenters to accelerate the delivery of high bandwidth, feature rich services worldwide.”

Verizon Builds its 100G ULH Backbone

Verizon continues to expand the number of 100G routes in its ultra-long-haul network in the U.S. and Europe, adding 100G technology to more than 4,800 miles of its global IP network during the first half of 2013.

The 100G expansion includes almost 4,500 miles on the Verizon U.S. network, bringing to approximately 21,400 the total number of 100G miles currently deployed on the network. Among the new 100G routes are Seattle to Salt Lake City, Indianapolis to St. Louis, St. Louis to Memphis, Charlotte to Nashville and Cleveland to Detroit.

The company has a goal of deploying an additional 8,700 100G miles in the U.S. by the end of the year.

In Europe, Verizon deployed 100G on an additional 350 miles between Brussels and Frankfurt, bringing to 5,100 the total number of 100G miles in Europe. The company plans to deploy an additional 1,400 miles by the end of this year.

Verizon is using Juniper PTX packet transport routers and the Ciena 6500 Packet-Optical Platform.

"Not only does Verizon have one of the largest global networks, we have one of the most robust and sophisticated networks with 100G technology deployed on multiple routes in the U.S. and Europe,” said Kyle Malady, senior vice president of global network operations and engineering. “As long as our bandwidth demand grows, we’ll continue deploying high bit-rate technology that underlies the superior experience that our business and consumer customers expect."

Last month, Verizon completed a field trial of 200G technology on a network route between New York and Boston.

The trial, which ran for more than a month on the live network, used the same hardware that currently supports Verizon's 100G ultra-long-haul traffic, along with pre-production software to configure a Ciena Wavelogic3 coherent optical processor. The trial used 16QAM (quadrature amplitude modulation) on a single wavelength with the typical 50GHz channel spacing to increase the amount of traffic carried.

Verizon said the test proves the ability to double spectral efficiency while reducing the cost per bit when compared with 100G technology.
