Calix, Inc. (NYSE: CALX) has unveiled the AXOS E3-2 Intelligent PON Node. The system is designed to enable distributed access network architectures by moving the OLT, routing, and IP policy and accounting functions from the headend or central office into the network toward the subscriber. Such an architecture is particularly useful for cable operators who want to leverage PON technology in fiber deep architectures because it can significantly reduce opex, Calix asserts.
The AXOS E3-2 features an environmentally hardened, modular "deploy anywhere design" that can be mounted aerially, on a pole, on a wall, or in a pedestal. It also can be easily upgraded to 10-Gbps and eventual higher-speed PON technologies, according to the company. It enables operators to distribute network intelligence and consolidate existing headend or central office facilities.
The AXOS E3-2 also supports Calix's Software Defined Access (SDA) approach. Operators can deploy software features deep into the network while using the zero touch activation and nodal management capabilities of the AXOS operating system and Activate cloud-based element management system to simplify system and network management. The E3-2 therefore helps cable operators create virtualized architectures in an SDN multi-vendor, multi-technology environment as a PON-based alternative to distributed CCAP, Calix says.
The E3-2's Layer 3 support means it can be used in routed architectures and enforce Layer 3 policy and accounting. The system therefore provides visibility into the traffic entering the network and enables subscriber management, including subscriber accounting and the use of policy and filters to prevent network attacks, the company adds.
"As gigabit services have become the gold standard in highly competitive broadband markets, service providers of all types are looking for new ways to provision network infrastructure to support gigabit services to meet increasing customer demand," said John Kendall, principal analyst, Connected Home at IHS Markit. "Regardless of platform, service providers are increasingly looking to deploy PON deeper into their networks in order to leverage existing last mile access infrastructure and still deliver symmetrical gigabit residential services. Once deployed, an OLT at this point in the network allows the service provider increased flexibility and control over the configuration of their network infrastructure, allowing for a coexistence with remote PHY architecture and network function virtualization."
"The E3-2 allows operators to effectively extend the reach of the data center seven-fold and reduce their operational costs by up to 80%, while at the same time facilitating the transition to the Software Defined Access revolution of the future," added Michel Langlois, Calix senior vice president of systems products. "When combined with Compass products like Open Link Cable that allow seamless integration into DOCSIS provisioning systems and existing fiber-deep architectures, the E3-2 is unquestionably the transformative vehicle service providers need today to stay ahead of their competition and the demands of their subscribers."
