Xtera's subsea repeaters enable C+L transmission on Seaborn's ARBR cable

Seaborn Networks will use Xtera’s wideband repeater to enable C+L band capability for its new ARBR cable between São Paulo and Buenos Aires.

The ARBR submarine fibre optic cable system, which is a fully-funded project developed jointly by Seaborn Networks and the Werthein Group. The 2,700 km open system, 4-fibre pair, 48Tbps, direct PoP-to-PoP subsea cable will connect Argentina and Brazil. The ARBR subsea cable system will allow for direct onward connectivity to New York, via the new Seabras-1 system.

Xtera’s wideband repeater is a hybrid Raman / EDFA design and can be configured to provide bandwidth in the C band alone, or across the C+L bands. First deployed in 2015, Xtera’s addition of Raman amplification to standard repeater technology has been used to achieve bandwidths of approximately 70 nm, while also offering very low noise solutions. Xtera said development continues to increase the capacity on a fibre pair to well over 100Tbit/s, further demonstrating that high capacity solutions do not have to mean large and costly fibre count systems.

In comparison, standard subsea repeaters use a single frequency band to carry the traffic. Seaborn said that by putting both the C and L frequency bands into ARBR’s cable on a fiber pair basis, it can pick and choose which fiber pair uses both bands and which use a single band, therefore enabling a choice between the most cost-efficient deployment of a fiber pair (single band) or an ultra-high capacity fiber pair (C+L). Seaborn is therefore able to tailor the subsea solution of each fiber pair to match the needs of different customers. For instance, carriers, ISPs and enterprise customers need affordable bandwidth from Argentina, whereas hyper-scalers need the assurance of ultra-high capacity throughout the life of the cable system.

“We work constantly with our partners and customers in this dynamic Latin American market to develop subsea cable systems that meet their future bandwidth demands,” says Larry Schwartz, Chairman & CEO of Seaborn. “Use of Xtera’s technology on the ARBR system will allow Seaborn to offer the most advanced system under the sea with on-demand capacities of up to 44Tbit/s per fiber pair. Disruptive innovation like this resonates with our content provider customers and positions us to respond to their needs well into the future.”

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.


ASN will undertake construction of the subsea cable system, which is expected to be completed by mid-2019

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.
