WWZ Cuts Operating Costs in Half As it Partners With Calix to Build a Future-Proof Broadband Business

Leading Swiss cable operator is simplifying a next-generation network with the Intelligent Access EDGE, and tapping market insights to grow its broadband business

SAN JOSE, CA – October 22, 2020 – Calix, Inc. (NYSE:CALX, news, filings) announced that WWZ Energie AG, a leading Swiss quadruple-play cable broadband provider is future-proofing its business by partnering with Calix. WWZ is using the Calix Intelligent Access EDGE solution to complete a migration from coax-based DOCSIS to fiber, enabling it to offer high speed symmetrical bandwidth and deliver unmatched services to subscribers. At the same time, market insights from Calix position WWZ to build an end-to-end, data-driven business and own the subscriber experience. Since operationalizing this 10G-capable fiber-to-the-home (FTTH) network in the last year, WWZ has cut its operating costs by 50 percent.

Working with partner Broadband Networks, WWZ first deployed FTTH service last year. In the face of continuously increasing subscriber bandwidth demands, WWZ is turning up XGS-PON service across its network. The Swiss operator leveraged the AXOS® E9-2 Intelligent EDGE System to provision services in eight hours—a process that typically takes months. The simplified architecture has enabled the Swiss operator to embrace an everyPON strategy, upgrading to the 10G technology of its choice, when and where it is required.

“From the beginning, our shared vision for the future of the broadband business and focus on the needs of our subscribers have aligned well with Calix,” said Stefan Willi, chief technology officer for WWZ Energie AG and a keynote speaker on October 29 at ConneXions 2020. “The Intelligent Access EDGE gave us the flexibility we needed when we began deploying full fiber to replace our copper-based network, knowing that we would eventually use the 10G capacity. Deploying XGS-PON drives new value and greatly expands our ability to deliver innovative new services. All future physical layer investments will be fiber—not DOCSIS—and Calix Marketing Cloud will help us be strategic as we continue to develop our migration strategy and significantly improve our subscribers’ broadband experience.”

Zug-based WWZ, one of the leading cable operators in Switzerland, first announced its digitization initiative last year. The initiative enables it to provide a rich broadband experience with the benefits of symmetrical high-bandwidth broadband—previously unattainable through the legacy DOCSIS infrastructure.

“WWZ dramatically simplified its network architecture and operations with the Intelligent Access EDGE and has benefitted from decreased operational costs,” said Michel Langlois, chief development officer, Intelligent Access EDGE products for Calix. “Operationalizing Calix solutions has given it unmatched scalability, enabling it to easily deliver consistent services over the PON technology of its choice. WWZ is upgrading service to XGS-PON with ease thanks to its simplified network and innovating at the pace subscribers demand. This is another example of how Calix is helping a cable operator evolve from coax to fiber, leveraging the power of software to accelerate that transition. We are thrilled to grow this partnership with WWZ as it continues to innovate and deliver differentiated services to its subscribers.”
