Advanced Upstream Blog Series Introduction In the Advanced Upstream blog series we will explore how cable operators have traditionally managed upstream bandwidth capacity planning, how market dynamics and technical innovation are driving changes, and where things are likely headed in the coming years. In this entry we will discuss the “more Nodes” approach – how […]
Rolling out DOCSIS 3.1 alone will not be enough to meet long-term subscriber bandwidth demands, which is why many operators are linking their DOCSIS 3.1 rollout with the migration to distributed access architectures (DAA) like Remote PHY. To learn more about how VIAVI can help simplify your transition to Remote PHY, download our new solution […]

In this entry we will lay the groundwork for discussion of the […]
DWDM is moving into access networks at a higher rate than ever before. This includes cable service providers upgrading to the newer distributed access architecture (DAA), both cable and traditional telecom service providers to deliver business services, and wireless service providers as part of their centralized RAN (C-RAN) approach as well as a key part […]

Fiber is being pushed deeper and deeper into access networks worldwide as service providers continue to address subscriber demands for higher capacity services. Going “fiber deep” could be part of G.fast deployments for telco operators or Distributed Access Architecture (DAA) upgrades for cable companies, but the next step (or end step) is full fiber-to-the-premise (FTTP) […]
Change Ahead – How Network Maintenance Practices Are Evolving With The Rapidly-Changing HFC The recent pace of change in HFC networks has been dizzying compared to our previous gradual evolutionary path, but fortunately plant maintenance practices including plant leakage detection have evolved to stay ahead of the curve. The rapid expansion of FTTH offerings combined […]
The HFC Evolves Through the years, with the demand for additional speed and bandwidth cable systems have: Migrated from analog channels to 6 MHz SC QAM channels Migrated from modulation schemes from 16 QAM up to 256 QAM channels Migrated to DOCSIS 3.1 OFDM carriers consuming much larger areas of the spectrum Began migrating from […]
The industry has been a buzz about Gigabit-to-the-Home (GTTH). People want higher speeds no matter where they live and providers are in a race to win new customers – and keep existing customers in this new frontier. One reoccurring question throughout the industry has been, “What’s the best strategy for deploying GTTH?” The question implies […]
It goes without saying that the relentless customer demand for faster broadband speeds is a double-edged sword for cable operators. It keeps all of us in this industry employed, but at the same time presents challenges to the way that things have always been done to deliver this service to our customers. Our old tricks […]
