Infinera lights 10,600km Seabras-1 subsea cable

Seaborn Networks (Seaborn) announced the deployment of Infinera’s new XTS-3300 meshponders on its Seabras-1 submarine cable, which spans 10,600-km and offers a direct connection between São Paulo, Brazil and New York City.  The new subsea cable, which is now ready for commercial service, enables Seaborn to offer SeaSpeed, its proprietary lowest-latency route, between these key global financial centers.

Seabras-1 is the longest uncompensated cable connecting North and South America. It has multiple branching units and is designed to provide additional route diversity to Virginia Beach, Miami, St. Croix, Fortaleza, Rio de Janeiro, southern Brazil and Cape Town.


Infinera said Seaborn selected its XTS-3300 to deliver the industry’s highest subsea spectral efficiency and lowest power consumption. While many subsea cables can take days to activate capacity, the Seaborn team was able to configure the XTS-3300 and light the fiber in an impressive 30 minutes.

Infinera noted that its unique large-scale photonic integration technology delivers terabit super-channels and, along with the Advanced Coherent Toolkit (ACT), enables rapid activation of subsea links. Infinera Instant Bandwidth enables Seaborn to deploy bandwidth in 100 Gb/s increments within minutes and a few clicks of a mouse, while the XTS-3300 platform enables scalability up to 11.8 terabits per second on a fiber.

Infinera also noted that the XTS-3300 seamlessly integrates with Seaborn’s existing Infinera terrestrial backhaul networks in Brazil and New York, which include Infinera’s XTC and XTM Series.

“Infinera continues to push the physics of the optical transport world for the benefit of our customers and the networks they run. The XTS-3300 is purpose-built for subsea applications, delivering industry leading subsea performance while integrating seamlessly into Seaborn’s existing terrestrial and subsea network,” stated Tom Fallon, Infinera Chief Executive Officer.

Infinera also confirmed that the ICE4-based XT-3300 and XTS-3300 are now shipping. Earlier this year Infinera began shipping the ICE-4 based Cloud Xpress 2, the second generation of its metro data center interconnect platforms.

NEC begins construction of 3 subsea cables in Micronesia

NEC, in partnership with Belau Submarine Cable (BSCC) and the government of the Federated States of Micronesia (FSM), announced it has commenced construction of three submarine cable links that will connect the islands of Palau, Yap and Chuuk in the western Pacific Ocean to the global network.

BSCC, supported by a loan from the Asian Development Bank (ADB), has signed a supply contract with NEC to build the spur to Palau, while FSM, backed by a grant from the World Bank (WB), has signed a supply contract with NEC to construct the spur to Yap, and recently signed an additional agreement for the extension from Pohnpei to Chuuk.

The spurs to Palau and Yap will both interconnect with the SEA-US cable system, also under construction by NEC, which connects the Philippines and Indonesia to the west coast of the U.S. via Guam and Hawaii. In addition, the extension from Pohnpei, the capital of FSM, to Chuuk branches out of another existing cable linking FSM, the Marshall Islands and Guam. All three routes feature transmission speeds of 100 Gbit/s per channel.

BSCC is a state-owned entity of the Republic of Palau with responsibility for the submarine cable project. BSCC has signed an IRU agreement with GTI (a subsidiary of Globe Telecom) for the provision of 5 x 100 Gbit/s wavelengths and a branching unit (BU) on the SEA-US West subsystem linking Indonesia, the Philippines and Guam. It has also contracted NEC to supply a spur cable linking the BU on the SEA-US West subsystem to Palau.

On completion of the project, BSCC will provide open bandwidth access to the international cable system for domestic telcos.

In addition, DTCI has signed an IRU agreement with Telkom Indonesia (Telin) for 5 x 100 Gbit/s wavelengths and a BU on the main trunk of the SEA-US West subsystem, plus a supply contract with NEC to deliver a spur cable linking the BU on the SEA-US West subsystem to Yap, along with a contract extension that includes a cable linking Weno Island Chuuk to the existing spur on to the HANTRU-1 cable system in Pohnpei to Guam.

Ownership and implementation responsibilities for the cable systems will pass from DTCI to the newly established FSM Telecommunications Cable (FSMTCC) which, as owner of the Yap and Chuuk cable systems, will provide open bandwidth access to the international cable systems for domestic telcos.
