BASKING RIDGE, NJ – Verizon is supercharging the core of its fiber network by upgrading older router equipment with new equipment, capable of utilizing the latest 400 Gbps per port optical technology. When the overhaul of the fiber core network (the superhighway Verizon uses to move customers’ data) is complete, Verizon will be able to manage 115 Tbps of data, the equivalent of almost 24 billion streaming songs, at any given moment. This upgrade will significantly increase the bandwidth needed to support wireless, home internet, enterprise, small business and FIOS customers.

“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.

In addition to providing the increased bandwidth needed for data growth over the next decade, the new equipment provided by Juniper Networks, Inc. offers many additional operational benefits:

  • The 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.

  • The new equipment offers an advanced level of automation, allowing for automated interfaces with other network systems to make faster decisions and changes, improving reporting telemetry to advance analytics and real-time adjustments to address congestion or other performance improvements, and incorporating protocols like segment routing to make more intelligent routing decisions. These automations will make the Verizon network even more reliable, programmable and efficient. 

  • Additionally, because this new equipment is so dense with such large capacity, Verizon will be able to redesign 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.
