Adtran has introduced its environmentally sealed, 10G-EPON virtual Remote-OLTs, further broadening its software-defined access portfolio. These new elements provide cable MSOs the ability to further execute on their 10Gbps FTTH and SD-Access strategies, while seamlessly integrating into existing DOCSIS back office provisioning and operational systems.

This combination of three critical and field proven capabilities — DOCSIS provisioning of EPON (DPoETM), native SDN integration and remote outside plant packaging — enables the company to capitalise on evolving distributed access architecture deployments as cable operators look to leverage next-generation FTTH to enhance support for high-bandwidth services.

“The network impact of supporting more bandwidth is demanding that service providers make a significant architectural shift. The emergence of low latency augmented and virtual reality applications is also forcing providers, including cable MSOs, to re-evaluate their network infrastructure,” said Rupert Wood, research director at Analysys Mason.

“Distributed, Remote-OLT access architectures, by moving FTTH electronics into the outside plant, afford the operator a network that can support much higher access speeds and subscriber capacity while also alleviating head end space congestion.”

Traditional FTTH network growth required MSOs to overcome capital, operational and regulatory hurdles, while requiring time-consuming and costly permits for adding new fibre from the headend, which slowed their ability to turn up services in a timely fashion. DAA and R-OLTs alleviate many of these issues.

Virtualisation alternative
Alternatively, the Layer 3 and other functionality can be virtualised affording additional cost reduction benefits as the R-OLT architecture is simplified further. Adtran’s OLTs bridge the management horizon with support of both DPoE management and modern SDN control protocols allowing MSOs to effectively execute over time their transition to virtualised, managed and orchestrated SD-Access service architectures.

Hossam Salib, VP cable and wireless strategy at Adtran, said, “Combining this OSP experience with our field-proven, standards-compliant DPoETM solution and our SD-Access leadership uniquely qualify Adtran to meet the requirements of a range of evolving DAA strategies.”

Adtran Mosaic is facilitating the MSO community’s transition to standards-based SD-Access through distributed, virtualised energy-efficient 10Gbps fibre architectures. The company’s virtual R-OLTs portfolio of multi-port 10G-EPON devices reduces time-to-market and subscriber connection costs by using the desired FTTH and DAAs needed to effectively deliver higher-speed triple play services.

The company showcased these differentiated solutions at Cable-Tec EXPO in Denver, Colorado, US, between October 17-20.
