Comcast lights 10G connection powered by DOCSIS 4.0

Comcast activated the first multigigabit, symmetrical Internet connection powered by 10G and full duplex DOCSIS 4.0, connecting a business location in the Philadelphia region to its live network.  The test involves a DOCSIS 4.0-enabled 10G node and multiple cable modem.

Comcast anticipates offering 10G-enabled services to customers in the second half of 2023.

“This live trial combines years of technology innovation and versatility to create a clear path to next-generation speed, reliability and performance for all the homes in our footprint, not just a select few,” said Charlie Herrin, President, Technology, Product, Experience at Comcast Cable. “What excites us most about 10G technology is the ability to continue our longstanding commitment to delivering our best technologies to everyone we serve.”

“We started this year with the announcement of our world-first test of 10G modem technology capable of delivering multi-gig speeds to homes and, as of today, 10G is a reality with the potential to transform and evolve the Internet as we know it,” said Elad Nafshi, EVP and Chief Network Officer at Comcast Cable. “It’s been an incredible year of progress, and we look forward to continuing to refine and harden our 10G technology as we work to make this service—and all its incredible benefits—available to all customers in the years ahead.”

Microsoft acquires Lumenisity, a developer of hollow core fiber

Microsoft has acquired Lumenisity Limited, a start-up based in the UK developing hollow core fiber (HCF). Financial terms were not disclosed.

Lumenisity’s next generation of HCF uses a proprietary design where light propagates in an air core, which has significant advantages over traditional cable built with a solid core of glass, including:

  • Increased overall speed and lower latency as light travels through HCF 47% faster than standard silica glass.
  • Enhanced security and intrusion detection due to Lumenisity’s innovative inner structure.
  • Lower costs, increased bandwidth and enhanced network quality due to elimination of fiber nonlinearities and broader spectrum.
  • Potential for ultra-low signal loss enabling deployment over longer distances without repeaters.

Microsoft said it made the acquisition to optimize its global cloud infrastructure and serve its Cloud Platform and Services customers with strict latency and security requirements.

  • Earlier this month, Lumenisity completed the development of the world’s first dedicated HCF manufacturing facility in Romsey, UK. The state-of-the art building spans 40,000 sq ft and will enable scaled up production of HCF technology in the future.

Ericsson completes first live 5G data call on Ericsson Cloud RAN

Telstra completed the first Ericsson Cloud RAN 5G data call on its commercial network in Queensland, Australia. 

Ericsson’s Cloud RAN solution virtualizes the RAN baseband as cloud-native network functions for the CU (centralized unit) and DU (distributed unit).

Telstra’s implementation of Ericsson’s Cloud RAN technology employs an architecture in which both the CU and DU baseband functions are centralized versus approaches that only centralize the CU and leave the DU at the base station site. By placing both the CU and DU functions at a central site such as a Telstra local exchange or data center, Telstra will achieve more efficient utilization of compute resources leading to improved cost and capacity outcomes.

The centralized Cloud RAN architecture deployed by Telstra is facilitated by the recently announced world-first commercial network deployment of Ericsson’s packet fronthaul technology based on the Ericsson Router 6673. Packet fronthaul technology allows existing site radios to be connected to the centralized Cloud RAN solution using eCPRI (enhanced CPRI). eCPRI is both more bandwidth efficient and places the radio information in an ethernet-based format that easily connects to cloud infrastructure running the Cloud RAN CU and DU baseband functions. 

Another unique aspect of Telstra’s Cloud RAN commercial network trial is that it is the first deployment of the Cloud RAN solution on Ericsson’s Cloud Native Infrastructure Solution (CNIS), - a bare metal infrastructure that is specifically optimized for hosting cloud-native 5G applications both at central data centers and at the edge. The combination of Ericsson’s Cloud RAN running on CNIS as a system-verified solution reduces Telstra’s deployment and operational risks and ensures the best mobile network performance for Telstra’s customers.

Iskra Nikolova, Telstra’s Network and Infrastructure Executive, says: “Telstra’s ongoing partnership with Ericsson has reached another new milestone this week with the first 5G Cloud RAN data call over our commercial network utilizing Ericsson’s industry-leading Cloud RAN technology. This achievement clears the way for the wider deployment of Ericsson’s Cloud RAN technology, which will enable the full benefits of 5G for Telstra’s customers across Australia.”

Emilio Romeo, Head of Ericsson, Australia and New Zealand, says: “Ericsson’s Cloud RAN technology is a key enabler of 5G-as-a-service-based architecture and supports Telstra’s move towards the widespread virtualization and automation of its network infrastructure. This Australia first Cloud RAN trial further demonstrates the industry leading innovation made possible by Ericsson’s ongoing partnership with Telstra while marking the next step in the transformation of Australia’s largest mobile network.”

Orange to provide landing in Marseille for Medusa Mediterranean cable

Orange will offer a high-performance interconnection solution to all partner operators of the new Medusa Submarine Cable System -- the first and longest submarine cable to connect the main Mediterranean countries. 

Medusa is an 8,760 km subsea system linking the North African countries and six EU member states (Portugal, Spain, France, Italy, Greece, and Cyprus). 

Medusa is an open system that includes 16 landing points around the Mediterranean Sea. The cable will have segments withup to 24 fiber pairs with a capacity of 20 Tbps per fiber pair. Its festoon architecture gives it a unique design. 

It is expected Medusa cable reaches Marseille during the last quarter of 2024. The system will be ready for service end of 2024 for the West Med region and first half of 2025 for the East Med region.

Orange is building submarine cable landing infrastructure in Marseille to make France more attractive as a digital gateway for global exchanges.

Construction includes new urban infrastructure to increase the resilience and diversity of access and landing points in Marseille while connecting all the city’s data centers.

Orange will handle all the technical, regulatory, security, and environmental aspects, enabling its partners to enjoy a prime position in Marseille and strengthening France’s attractiveness

"We are particularly pleased to welcome the Medusa cable to Orange's infrastructure in the heart of the Mediterranean hub of Marseille, as part of a strategic and ambitious project. By combining our submarine cable landing stations with our new urban infrastructure, we are strengthening Marseille's attractiveness as a digital gateway to Europe, and beyond that, France's sovereignty," explains Michaƫl Trabbia, interim CEO of Orange Wholesale & International Networks.

Norman Albi, CEO of Medusa, stresses the importance of this agreement: “Marseille has always been a strategic Mediterranean interconnection point and joining forces with Orange means we can offer a cutting-edge service, against a background of growing needs in the digital economy. With this agreement, all Medusa landings in the western Mediterranean are totally secure and ready to be implemented.”

T-Mobile US advances deployment of 1900 MHz mid-band

 T-Mobile has achieved its year-end goal of covering 260 million people with Ultra Capacity 5G weeks ahead of schedule. In addition, T-Mobile has now deployed an additional, new layer of 1900 MHz mid-band Ultra Capacity 5G spectrum nationwide.

The operator has also begun lighting up three-carrier aggregation — combining three channels of mid-band 5G spectrum — which in tests produced peak speeds topping 3 Gbps on T-Mobile’s 5G standalone network. Customers with the Samsung Galaxy S22 are leveraging the capability in parts of the network now. Three-carrier aggregation will expand nationwide, and be accessible by additional devices, in the near future.

"We’re rapidly executing on our vision to deliver the highest capacity network this country has ever seen,” said Neville Ray, President of Technology at T-Mobile. “We’ve led in 5G coverage from the beginning, delivering a massive 5G footprint that continues to grow. And with Ultra Capacity 5G, it’s undeniable that T-Mobile customers have access to the most powerful 5G network around.”
