Ciena adds L-Band to its subsea GeoMesh Extreme

Ciena is boosting the horsepower of GeoMesh Extreme submarine solution by adding support for L-Band spectrum. The platform also gains the ability to operate on TE SubCom’s L-Band wet plant system, nearly doubling the information-carrying capacity of a submarine cable.

Specifically, in addition to current C-Band (~ 1530nm to 1565nm) spectrum, Ciena’s GeoMesh Extreme solution now opens up the L-Band (~ 1656nm to 1625nm) in the same optical fiber, doubling the carrying capacity of an undersea cable.

Some highlights:

  • The same technology used by Ciena’s C-Band SLTE, which is deployed worldwide, is ported to the new L-Band SLTE to ensure the highest level of performance. Ciena has already deployed in the L-Band over terrestrial networks for many years and will leverage this extensive knowledge, expertise, and field experience to ensure a seamless migration into the L-Band in submarine networks.
  • TE SubCom announced earlier in 2017 that it has demonstrated a new transmission record of 70.4 Tb/s capacity over 7,600 km. This record transmission is made possible utilizing SubCom’s C+L technology, effectively doubles the available transmission bandwidth of the repeater by an unprecedented factor of two in supported capacity per fiber pair when compared to the same number of fiber pairs in traditional C-Band technology.
  • Submarine cable operators will also benefit from Ciena’s advanced Blue Planet MCP solution that allows for managing the Ciena C/L-Band SLTE and TE SubCom C/L-Band wet plant from a single, unified management platform for a seamless, end-to-end, best-in-breed Open Cable.

“Our partnership with TE SubCom has been critical in ensuring that customers can meet demand growth while delivering the highest level of performance. Leveraging L-Band, over and above the traditional C-Band, changes the economics of submarine network connectivity by providing unprecedented improvements in capacity, reliability, and simplicity,” stated Steve Alexander, Chief Technology Officer, Ciena.

Google Joins INDIGO Undersea Cable Project

A consortium comprising AARNet, Google, Indosat Ooredoo, Singtel, SubPartners and Telstra announced that they have entered into an agreement with Alcatel Submarine Networks (ASN) for the construction of a new subsea cable system.

On completion, the new INDIGO cable system (previously known as APX West & Central) will expand connectivity between Australia and South East Asia markets, and will enable higher speed services and improved reliability.

The INDIGO cable system will span approximately 9,000 km between Singapore and Perth, Australia, and onwards to Sydney. The system will land at existing facilities in Singapore, Australia and Indonesia, providing connections between Singapore and Jakarta.

The system will feature a two-fibre pair 'open cable' design and spectrum- sharing technology. This design will allow consortium members to share ownership of spectrum resources provided by the cable and allow them to independently leverage technology advances and implement future upgrades as required.

Utilising coherent optical technology, each of the two fibre pairs will provide a minimum capacity of 18 Tbit/s, with the option to further increase this capacity in the future.

In addition to Google, the INDIGO consortium is made up of: AARNet, a provider of national and international telecom infrastructure to Australia's research and education sector; Indosat Ooredoo, an Ooredoo Group company providing telecom services in Indonesia; Singtel of Singapore, with a presence in Asia, Australia and Africa; and SubPartners based in Brisbane, Australia, which focuses on delivering major telecoms infrastructure projects in partnership with other companies.

TE SubCom Carries 70.4 Tbit/s over 7,600 km using C+L

TE SubCom, a TE Connectivity company and provider of subsea communications technology, announced that it has demonstrated what it claims is a new record transmission capacity of 70.4 Tbit/s over a distance of 7,600 km.

The record transmission utilised SubCom's newly available C+L technology, which features amplifiers delivering nearly 10 THz of usable optical bandwidth, a transmission line designed to minimise noise accumulation and enhance performance, a new transmission format based on multi-dimensional coded modulation with hybrid probabilistic and geometrical constellation shaping, and digital signal processing providing mulitple stages of non-linear compensation.

SubCom announced earlier this year that it would deploy C+L technology in an undersea cable that it had started manufacturing in late 2016. SubCom's C+L is designed to effectively double the available transmission bandwidth of the repeater compared to the same number of fibre pairs utilising traditional C-band technology. As half the number of fibre pairs are needed compared to a C-band repeater, the C+L technology can enable higher performance and more cost effective submarine systems.

TE SubCom announced in January that it had begun manufacturing of C+L optical transmission technology, designed to provide cable system operators with ultra-wide, low-latency transmission performance and effectively doubling available bandwidth and capacity per fibre pair.

The C+L technology leverages a second length of erbium-doped fibre in undersea repeaters that provides both amplification and support for wavelengths on the long wavelength side of the traditional C-band for telecommunications applications. TE SubCom stated at that time that it was manufacturing cable with the new technology for a contracted system scheduled to launch in 2018. The company noted that a trans-Atlantic cable with eight fibre pairs equipped with C+L technology would be able to deliver capacity of up to 325 Tbit/s.

The results of the TE SubCom transmission technology demonstration were announced at the recent OFC conference in Los Angeles.

Alaska Comm Extends with Quintillion Subsea Cable

Alaska Communications announced that leveraging Anchorage-based infrastructure company Quintillion's new submarine optical cable it is bringing new services to Alaska's northernmost communities, including Utqiaġvik (formerly known as Barrow), Nome, Kotzebue, Point Hope and Wainwright.

Through the project, corporations, government agencies, healthcare and education institutions in the northwest region of Alaska will gain access to reliable high-speed broadband and managed IT services for the first time.

Quintillion's infrastructure will enable the provision of commercial high-speed connectivity in areas where previously only costly microwave and satellite communications were available from a single provider. The new fibre network will support lower cost, high-speed access to the communities in northwest Alaska.

Alaska Communications, the leading broadband and managed IT services provider in the state, noted that when the new network becomes available later in 2017 it will act as a reseller to select telecom carriers, as well as serving business customers using the expanded network. In addition, as part of the agreement Quintillion will purchase capacity services for its new terrestrial system linking the oil fields of the North Slope on Alaska Communications' fibre network from Fairbanks to the U.S.

Alaska Communications noted that it first partnered with Quintillion in 2015 when it acquired a fibre network from ConocoPhillips in the part of Alaska's North Slope where most recent oil and gas exploration is occurring. The new agreement allows Alaska Communications to connect the original fibre to its existing network via Quintillion's new terrestrial network, providing redundancy and extending broadband and managed IT services to more oil and gas companies on the North Slope.

Quintillion is aiming to deliver affordable, carrier-class broadband services in Alaska, and with partners is specifically seeking to develop Alaska's middle-mile capabilities via the construction of new cable systems.

In May 2016 Quintillion announced it had acquired the assets of Arctic Fibre as part of a plan to build a submarine fibre optic cable from Asia to Europe, with the first phase in Alaska. Arctic Fibre is planning to deploy a Europe-Asia submarine cable system linking Nome to Prudhoe Bay in Alaska, Nome to Tokyo, Japan and form Prudhoe Bay to England, with additional spurs to Arctic Canada.

Infinera Upgrades and Expands DTN-X Platform for Cloud-Scale Subsea Networks

Infinera is expanding its DTN-X family with new platforms to power cloud scale subsea networks, where bandwidth demand is rapidly rising due to Internet content providers who are moving content around the globe between data centers. This traffic is dominated by N x 100 Gbps elephant flows. Infinera said subsea operators need to maximize the fiber capacity of their cable plants and simultaneously optimize their networks to efficiently handle these 100 Gbps flows and support smooth scale-out of capacity.

Infinera introduced the XTS-3300 and XTS-3600 meshponders for subsea networks, and upgraded its DTN-X XTC Series to 12 Tbps of non-blocking Optical Transport Network (OTN) switching with a new 1.2 Tbs subsea line card. The solution features dynamic spectral sharing and access to real-time subsea link performance. Some highlights:

  • DTN-X XTS-3300 and XTS-3600 meshponders. The compact 1 rack unit (1RU) and 4RU plug-and-play subsea platforms integrate Infinera's new Infinite Capacity Engine with the Advanced Coherent Toolkit (ACT) for enhanced capacity and reach. The industry’s first meshponders combine 2.4 Tbps super-channels with sliceable photonics and in-flight line-rate Layer 1 encryption in a compact and lower-power form factor. They support Infinera’s unique Instant Bandwidth capability, providing rapid bandwidth management and service provisioning for success-based growth. The XTS Series features long-reach subsea-optimized modulation formats providing best-in-class capacity, as well as the industry’s first commercially available Nyquist subcarriers to improve transmission performance and soft-decision forward error correction (SD-FEC) gain sharing to maximize capacity. The new platforms seamlessly interoperate with Infinera’s DTN-X XTC and XT Series, providing a unified end-to-end Intelligent Transport Network portfolio that enables end-to-end services covering subsea, long-haul, metro and data center interconnect applications.
  • DTN-X XTC Series upgrade. The Infinera DTN-X XTC-4 and XTC-10 have been upgraded with subsea-optimized and Instant Bandwidth-enabled 1.2 Tbps line modules. The XTC-4 and XTC-10 platforms now have more than twice the switching and transmission capacity, enabling up to 12 Tbps of OTN switching via non-disruptive in-service upgrades. The new line modules coexist with previously deployed modules, thereby protecting prior investments in DTN-X platforms. The DTN-X XTC Series now offers up to 12 Tb/s of non-blocking switching capacity with ODU0-level switching granularity in a single unit, and unlike competitive systems, has no tradeoffs between client-side tributary capacity and line-side capacity.
  • New subsea software tools for open systems. Dynamic spectral sharing enhances Infinera’s open architecture, allowing subsea operators to partition and monetize valuable fiber spectrum so that it can be securely shared with multiple tenants, independent of both cable and submarine line terminal equipment suppliers. Mission-critical subsea link performance data is available in real time, on-demand, via open software-defined network application programming interfaces. This enables subsea operators to monitor transmission health as well as identify opportunities for capacity adjustments. In addition to these new tools, Infinera’s Time-based Instant Bandwidth enables operators to instantly change network capacity as well as duration, facilitating a dynamic Intelligent Transport Network. Now operators can closely match traffic patterns to address bursty service demands from customers, match bandwidth to revenue, and instantly reroute bandwidth in the case of network disruptions.
Infinera is also expanding the capabilities of its  Advanced Coherent Toolkit, which increases capacity and reach on submarine cables to include Nyquist subcarriers and SD-FEC gain sharing, 3QAM (quadrature amplitude modulation), matrix-enhanced phase-shift keying (ME-PSK) that surpasses binary phase-shift keying (BPSK) reach performance, and a new, high-gain SD-FEC algorithm.

Infinera has validated the benefit of Nyquist subcarriers in customer trials demonstrating approximately 20 percent increase in reach compared to single carrier transmission, facilitating increased capacity via higher spectral efficiency. The trials also validated SD-FEC gain sharing in which high-margin carriers share excess margin with carriers at lower optical signal-to-noise ratio (OSNR) to improve performance, increasing capacity. These new capabilities are controlled by Infinera’s Xceed Software Suite and managed by Infinera’s Digital Network Administrator (DNA).

The XTS-3300 platform is planned for availability in the second quarter of 2017, with the XTS-3600 platform and the 1.2 Tb/s subsea line module for the XTC-4 and XTC-10 platforms to follow shortly thereafter.

“Infinera is committed to bringing advanced features to the subsea market. The XTS Series offers unprecedented ease of installation and scale-out, advanced transmission performance, and the power of Instant Bandwidth to deliver real value to cable system operators,” said Scott Jackson, Vice President of Subsea Business Group at Infinera. “The new capabilities announced today deliver leading capacity and reach, and provide the tools essential for cloud scale subsea networks. We are pleased to show Infinera’s investment in the subsea market, with solutions enabling operators to rapidly and cost-effectively deliver scalable services across open networks.”

The third phase of construction includes a brand new 64,800-square-foot colocation facility, which could accommodate compute-heavy and content-rich applications that not only require a diverse carrier ecosystem, but also robust power density. In North America, NJFX has seven United States backhaul providers preparing to serve private fiber backhaul to cities across country, all while bypassing New York City and other legacy infrastructure.

The completion of Phase III coincides with NJFX’s powering of its first customer cage that uses the company’s 432 tie cable to provide ubiquitous connectivity across the NJFX campus and its Cable Landing Station (CLS) Meet Me Room. Moving forward, carriers across the United States will begin the process of interconnecting the NJFX campus with their self-managed fiber cables, using the NJFX 8 POE’s designed to support well over 300 varying terrestrial and subsea fiber cables, thereby allowing on and off ramps between South America, Europe and the Caribbean via its Atlantic Ocean gateway.

NJFX said its fully-built colocation campus now offers capacity for 1,000 cabinet equivalents with power densities up to 20kW/cabinet load.

“2016 was an outstanding year for NJFX,” states Gil Santaliz, Founder and Chief Executive Officer of NJFX. “We launched the facility in September and since then have developed key strategic partnerships with a multitude of networks and successfully completed our data center commissioning. As we head into 2017, we look forward to further developing our campus’ ecosystem, one of the most robust and diverse in the market.”

Italy's Retelit Powers Ultra-high Capacity Transport Network with Coriant

Retelit, a leading Italian provider of data and infrastructure services to the telecommunications market, has selected Coriant’s 100G technology to support end-to-end delivery of high-capacity, low latency services on its recently expanded fiber optic infrastructure.

The Coriant coherent optical transmission solution will power a resilient, 100G terrestrial transit network for end-user traffic traversing Europe and Asia via Retelit’s AAE-1 (Asia Africa Europe 1) subsea landing station in Bari, Italy. Retelit’s network project will serve as the backbone for AAE-1 transit traffic.

The deployment uses the Coriant hiT 7300 Multi-Haul Transport Platform and Coriant CloudWave Optics coherent interface technology. Coriant said its advanced transmission technologies and sophisticated optical layer planning tools enable Retelit to maximize the reach, capacity, and flexibility of its high-speed transport infrastructure, while reducing operational costs and complexity. Retelit will also use the Coriant Transport Network Management System (TNMS) to simplify and accelerate end-to-end service provisioning.

“The launch of AAE-1 will unleash new demand for high-capacity, low latency terrestrial transit across Italy,” said Richard Fellner, Regional Vice President, EMEA, Coriant. "We are pleased to be a strategic technology partner with Retelit and help them capitalize on emerging market opportunities with a best-in-class solution and unmatched service excellence.”
