Telxius’ BRUSA hits 160Tbps with Ciena’s WaveLogic 5
turn those possibilities into reality.” Telxius is the global infrastructure company of the Telefónica Group, with one of the largest telecommunication sites portfolio in the world. Its more than 20,000 sites are located in Europe and Latin America: “Completing this trial showcases how WaveLogic 5 Extreme, which is an integral part of Ciena’s GeoMesh Extreme network solution, raises the bar in coherent optical technology and demonstrates how Telxius’ current network can be transformed to provide an even more superior digital experience for their customers,” added Rodolfo Vigliano, Ciena’s senior managing director of sales. interested in leveraging the principles of quantum physics to send unhackable information across long distances. Researchers at Argonne and UChicago plan to use the testbed to explore science underlying quantum engineering systems and to harness the properties of quantum entanglement, a phenomenon Albert Einstein famously characterised as “spooky action at a distance.” Quantum entanglement links two (or more) particles so that they are in a shared state — such that whatever happens to one immediately affects the other, no matter how far apart they have travelled.
50% more capacity per wavelength. Ciena’s GeoMesh Extreme, based on WL5e coherent optics, also demonstrated how BRUSA can benefit from open cable network designs, rapid scalability, and a lower total cost of network ownership. “WaveLogic 5 Extreme opens the door to a more scalable submarine network, which can support our customers as they continue to embrace new technologies that require unprecedented levels of bandwidth,” commented Carlos Dasi, Telxius’ Cable CTO. “This remarkable achievement is another example of how our collaboration with Ciena enables us to not only visualise what’s possible for our network, but to Scientists from the U.S. Department of Energy’s (DOE) Argonne National Laboratory and the University of Chicago launched a new testbed for quantum communication experiments from Argonne. The Argonne quantum loop consists of a pair of connected 26-mile fibre- optic cables that wind circuitously between Argonne to the Illinois tollway near Bolingbrook, IL, and back. At 52 total miles, it is currently among the longest ground-based quantum communication channels in the country. The loop will serve as a testbed for researchers
Telxius’ BRUSA submarine cable has successfully reached record 550 Gbps single-wavelength channel speeds during an advanced trial featuring Ciena’s WaveLogic 5 Extreme (WL5e) coherent optical solution. In addition, a commercially deployable solution was verified for a total capacity of more than 20 Tbps on a single fibre pair. With WL5e, the BRUSA cable is now able to reach a total transmission capacity of more than 160 Tbps. According to Ciena, the record-breaking trial has demonstrated how the BRUSA network can prepare for increasing connectivity demands from telecom operators, OTT services and other requirements driven
by high-bandwidth applications. BRUSA is the highest
capacity submarine cable connecting the Americas. It was opened for business in August 2018 and stretches approximately 10,200 km between Rio de Janeiro, Brazil, and Virginia Beach, USA. BRUSA enables ultra- high broadband services, improves communication reliability and overall network performance, and provides direct access to internet exchanges in Rio de Janeiro and São Paulo. The BRUSA network trial was powered by Ciena’s WL5e, the industry’s first programmable 800G solution. WL5e was used on the BRUSA cable to provide greater scale and increased economic efficiencies and deliver
CityFibre to buy FibreNation from TalkTalk
New quantum loop provides long national testbed for communication technology
UK alternative fibre to the home (FTTH) network operator CityFibre has agreed to acquire TalkTalk Group’s FibreNation FTTH infrastructure arm, including TalkTalk’s shareholding in Bolt Pro Tem Ltd, for £200 million has modified the terms of its FTTH roll-out agreement with Vodafone to enable CityFibre to more rapidly open to other service providers the fibre broadband infrastructure the agreement covers. (US$261 million) in cash. The company also says it
Service provider TalkTalk says the sale is contingent upon shareholder approval; the company expects the acquisition to close in March 2020. CityFibre adds the addition of FibreNation’s FTTH infrastructure will enable the company to expand its roll-out target from 5 million to up to 8 million premises. The agreement, if consummated, will see TalkTalk become a CityFibre customer for the provision of both residential and business services.
