Calix AXOS Accelerates Delivery of World’s First and Only True Gigabit Over Copper Solutions to MDUs

PETALUMA, CA– February 22, 2017 – Calix, Inc. (NYSE: CALX), the world leader in Subscriber Driven Intelligent Access, today announced the expansion of its industry-leading family of AXOS solutions to support a true gigabit experience to copper-fed subscribers in MDUs. Cutting-edge Collective Dynamic Timing Allocation (cDTA) technology has been added to the industry’s only bonded portfolio, delivering the world’s first symmetrical gigabit speeds over loops lengths up to 240 meters. An ideal solution for MDUs with copper wiring – especially those buildings passed by fiber infrastructure – this unique combination of technologies and solutions from Calix puts the promise of gigabit speeds within reach of millions of new subscribers around the globe. Since Calix solutions are built on AXOS, the world’s only true Software Defined Access architecture, they can be implemented into existing networks in a fraction of the time of traditional solutions.

“MDUs have always been a challenge for service providers – highly competitive, difficult to access, and operationally and financially challenging for new technology deployment,” said Teresa Mastrangelo, principal analyst and founder of BroadbandTrends. “ has reinvigorated interest in MDUs by mitigating many of those operational and financial barriers by utilizing existing copper to advanced broadband services to gigabit speeds. Now, innovations like cDTA and bonding will keep copper thriving within MDUs, giving service providers fiber-like performance to stay ahead of their competition while leveraging their existing infrastructure that provides a winning scenario for the service provider, the owner, and the subscriber tenant.”


cDTA is a game-changing technology for service providers leveraging over copper, as it allows service providers to fully utilize all the bandwidth available across a single or bonded copper pair. When a subscriber requires more upstream or downstream bandwidth, cDTA will dynamically change the ratio between upstream and downstream in less than 100 milliseconds. A powerful differentiated feature uniquely available today only in the latest chips from Sckipio, Calix was able to leverage the power of AXOS to quickly integrate this cutting-edge technology into its systems and enable service providers to be first-to-market with an unmatched subscriber experience over copper.  


Calix true gigabit solutions over are end-to-end, comprised of multiple AXOS-enabled system form factors, a variety of premises devices, and a family of Calix Cloud services that provide insights to lower OPEX and CAPEX while enabling an unmatched subscriber experience:


  • The Calix AXOS E3-16F Sealed Access Node and E5-16F Access Node feature 16 ports as well as support for cDTA and bonding for symmetrical gigabit speeds
  • The 844FB GigaCenter featuring Carrier Class Wi-Fi and the 801FB GigaPoint are the world’s only premises solutions that support bonding and a full symmetrical gigabit throughput
  • Calix Cloud provides powerful cloud analytics and management services, allowing service providers to discover new service offerings, simplify network operations and subscriber support, and transform their business

“AXOS has allowed Calix to stay on the leading edge of innovation and allowed our customers to rapidly integrate and deploy our solution in their networks,” said Shane Eleniak, Calix vice president of product line leadership. “That is why we have the most commercial deployments of technology in world, including North America’s largest deployment, while others are still struggling in trials. Now, our customers can further differentiate their services by leveraging cDTA and bonding to offer an experience to their subscribers that no other systems vendor in the world can enable – true symmetrical gigabit services over copper in MDUs.”
