CommScope Advances 10G Broadband Roadmap

CommScope announced several areas of progress on its 10G Broadband roadmap
  • A low-latency DOCSIS system deemed crucial to next-generation broadband performance. The company is demonstrating IP video running alongside traditional QAM video over an EPON channel at 10 Gbps. 
  • A software-configurable Frequency-Division Duplex (Soft FDD) system with the potential to deliver 10G speeds over traditional coaxial wiring. Soft FDD uses FDX technology and provides a foundation for symmetrical services.
  • The E6000 vCore fully virtualized converged cable access platform (CCAP) core. This offers automated provisioning and capacity tools for end-to-end service provisioning and smart capacity additions; and orchestration and intelligence tools to manage multi-access configurations and produce better analytics about network performance.

The three technologies will be demonstrated at the ANGA COM trade show.

CommScope notes that these announcements come fewer than six months after it revealed its role in pioneering the core technologies for 10 Gbps broadband (10G), and just four months after it announced a 8.5 Gbps network trial with Virgin Media.

In addition, Vodafone Germany is underway with a nationwide upgrade to support 1Gbps service. Some 12 million customers will enjoy the high-speed Gigabit service through an ARRIS broadband device when the rollout is complete. Swiss provider Sasag last month became the first European operator to announce upgrading its entire network to use DOCSIS 3.1 (D3.1) for both the upstream and downstream channels.

“As cable operators embark on their far-reaching network transformation, which includes the migration to 10G and virtualization of the CCAP, CommScope is rising to the challenge, delivering the complex solutions they will need such as low latency DOCSIS, soft FDD and virtualized CCAP,” said Liliane Offredo-Zreik, principal digital transformation analyst with consulting and market analysis firm ACG Research. “Operators’ needs in this transformation will be far from homogeneous; they will require a vendor with the depth and breadth of expertise and solutions to meet their evolving needs.”

CommScope completed its acquisition of ARRIS International in April.

TIM carries 550G wavelength with Nokia's Photonic Service Engine 3

 Nokia, in collaboration with Telecom Italia (TIM), set a new European record for data transmission over a long-distance backbone network -- a wavelength speed of 550 Gbps carried more than 350 km on TIM's operational network between Rome and Florence. In addition, TIM and Nokia carried a 400G wavelength over 900 km between Rome and Milan, and a 300 Gbps wavelength over 1,750 km.

The trial used the new Nokia Photonic Service Engine 3 (Nokia PSE-3). TIM'a DWDM backbone is based on the latest generation of Nokia's 1830 Photonic Service Switch.  The network is fully automated and currently carries optical signals with a capacity of 100 Gb/s over distances of up to 1,800 kilometers, and 200 Gb/s up to 800 kilometers. The backbone, with a coverage of over 16,000 kilometers of fiber, and connecting to 65 national POPs (Point of Presence), has carried over 9,000 petabytes of data traffic in the last year.

Elisabetta Romano, Chief Technology & Innovation Officer at TIM, said: "We are proud of this European record which confirms TIM's technological leadership, the high quality of our network, our commitment to develop innovative solutions in order to guarantee the best experience to our customers. Today's result, which triples transmission speed compared to the current one, confirms that TIM's network is the most advanced infrastructure capable of offering new digital services and platforms, also with a view to developing 5G."
