Verizon upgrades its core network for 400G with Juniper's PTX series

Verizon is refreshing its core network with Juniper Networks' PTX series routers supporting 400G interfaces. 

Verizon said the new equipment is half the size of the existing equipment, reducing space requirements in core facilities and driving down both power usage per GB and cost per GB to operate. In addition, the new equipment offers an advanced level of automation, allowing for automated interfaces with other network systems.

Verizon also highlighted the redesign of its network architecture to spread the equipment out to additional facilities across geographies, building in an additional level of redundancy with the ability to reroute traffic onto a greater number of fiber routes when needed. 

“Our fiber network is the largely invisible foundation that is a key driving force behind providing the scalability and reliability our customers need and expect,” said Kyle Malady. “This new packet core will provide the reliability and capacity we need today, but more importantly will be able to scale to meet the forecasted future demands that will result from the incredible capabilities of our robust 5G network, the platform for 21st century innovation.”

In June of this year, Verizon announced that data traffic on its 5G Ultra Wideband network had already increased 249%, and it expects exponentially higher increases as more customers adopt the new technology and begin to experience the robust capabilities and performance of 5G Ultra Wideband. The new optical core, which is being built to meet customers’ growing demands through 2032, is upgradeable to future 800 Gbps and 1 Tbps per port optical technology, allowing Verizon to manage 230 Tbps of data at any given time.


  • Juniper’s PTX10000 line is optimized for scale-up and scale-out architectures, supporting future 800G and boasting system capacity of up to 230.4 Tbps. The PTX10000 line is powered by Juniper’s current generation Express4 silicon and upgradeable to the coming Express5 silicon. The PTX also features native 400G inline MACsec encryption. Three configurable PTX10000 models have been announced: PTX10004 (4-slot), PTX10008 (8-slot), PTX10016 (16-slot).

Cirion spins out of Latin American operations from Lumen

Cirion, previously the Latin American operations of Lumen Technologies, officially launched as an independent company with approximately 86,000 kms of fiber, an extensive subsea cable network, and data centers in major economic centers across Central and South America.

Stonepeak, a leading alternative investment firm specializing in infrastructure and real assets, acquired the Cirion assets for US$2.7 billion. 

Lumen acquired the Latin American business in 2011 when it acquired the business of Global Crossing.

Cirion and Lumen plan to maintain a strategic partnership covering reciprocal reselling and network agreements that leverage each other’s extensive fiber footprints, data centers, and other network assets. 

All of Lumen’s LATAM employees and employees in the United States who are part of the LATAM organization, including its current leadership team, transferred to Cirion as part of the transaction.

“We believe technology is key to our digital future and know what it takes to drive industry change. We are confident that we have the right people, partners, and resources to bring fast, reliable, and exceptional services to our customers,” said Facundo Castro, CEO of Cirion. “We are very enthusiastic about the opportunities that lay ahead and look forward to positioning ourselves as the technological partner of choice for Latin America’s most relevant industries.”

“Closing this transaction marks the beginning of an exciting new chapter for Cirion as the company continues to expand its fiber and data center network across its already strong footprint in Latin America,” said Stonepeak Managing Director and Co-Head of Communications Andrew Thomas. “We are excited to partner with Cirion’s team and apply our experience as active investors in global digital infrastructure to drive sustainable long-term growth.”

"This divestiture is an important step in achieving Lumen's strategic goals as we sharpen our focus on key strategic assets while also providing our LATAM employees and customers an opportunity for continued growth," said Jeff Storey, Lumen President and CEO. "This transaction also positions our Lumen Platform for long term growth, allowing Lumen to invest in a strategic mix of assets and alliances that allows us to deliver what our customers want anywhere in the world."

Reliance Jio becomes India's biggest spectrum holder

Reliance Jio was the largest purchaser in the auction of 5G spectrum conducted by the Department of Telecommunications, Government of India, over the past week.

Jio confirmed that it acquired spectrum in the 700MHz, 800MHz, 1800MHz, 3300MHz and 26GHz bands. The company said it will use equipment made in India for its 5G rollout.

Jio's total cost of acquiring the technology agnostic spectrum for a period of 20 years is Rs. 88,078 crore. As per terms of the spectrum auction, the spectrum payments have to be made over 20 equated annual instalments, with interest computed at 7.2% per annum. 

Through this acquisition, Jio’s total owned spectrum footprint has increased significantly to 26,772 MHz (uplink + downlink), which is the highest in India:

  • Sub-GHz: Jio has the highest amount of sub-GHz spectrum with at least 2X10 MHz contiguous spectrum in both 700 MHz and 800 MHz bands across each of the 22 circles.
  • Mid-band: Jio is the only operator which has at least 2X10 MHz in 1800 MHz band (with 2X20 MHz in six key circles), 40 MHz in 2300 MHz band and 100 MHz in 3300 MHz band across all the 22 circles.
  • mmWave: In addition, Jio also has right to use 1,000 MHz in the millimetre wave band (26 GHz) in each of the 22 circles which will be crucial to enable enterprise use cases as well as provide high-quality streaming services.

Shri Akash M Ambani, Chairman, Reliance Jio Infocomm issued the following statement:

“We have always believed that India will become a leading economic power in the world by adopting the power of breakthrough technologies. This was the vision and conviction that gave birth to Jio. The speed, scale and societal impact of Jio’s 4G rollout is unmatched anywhere in the world. Now, with a bigger ambition and stronger resolve, Jio is set to lead India’s march into the 5G era. We will celebrate ‘Azadi ka Amrit Mahotsav’ with a pan India 5G rollout. Jio is committed to offering world-class, affordable 5G and 5G-enabled services. We will provide services, platforms and solutions that will accelerate India’s digital revolution, especially in crucial sectors like Education, Healthcare, Agriculture, Manufacturing and e-Governance and make another proud contribution to Honourable Prime Minister’s DIGITAL INDIA MISSION.”
