When developing a long-term access network transformation plan, network operators tend to focus on demand growth as the key trigger for upgrades. While accommodating demand growth remains a key driver for upgrading a network, in reality other triggers may enforce a different upgrade strategy and alter the preferred upgrade path and the required investment profile.

An operator wants to move all subscribers to Fiber to the Home. He decides on an aggressive strategy to no longer invest in DSL technology upgrades but migrate network elements to FTTH when they need to be upgraded and wants to understand what is the best starting point: go with GPON or directly introduce XGS-PON?

A cable operator is planning to use Extended Spectrum DOCSIS (ESD) technology to upgrade their access network. They are considering two network powering options – central powering vs distributed powering. Which powering model would be best suited for their future network upgrades?

An operator would like to develop a roadmap to reach 10G capacity on their access networks. To make an informed decision he wants to understand the effect of multiple technology paths on total cost, investment profile, technology availability risk and ability to support his product roadmap.

An operator would like to develop brownfield SFU upgrade guidelines. They have access to different access technologies such as Fiber Deep and Fiber To The Home in their portfolio. Question is what are the guidelines for deploying technologies for different node densities?

An operator is interested in understanding what is the operating cash flow (OCF) opportunity by installing different fiber deep technologies to brownfield MDUs in a market. They have a hypothesis that different fiber deep technologies will have different take rates.

An operator would like to develop a focused short-term greenfield expansion plan with an understanding of short-term and longer-term cost trade-offs. Currently, XGS-PON is more expensive than GPON. Should they initially execute their expansion plan with GPON or XGS-PON?

A brownfield N+5 DOCSIS3.0 node is running out of capacity and needs to be upgraded. Which option should be used to upgrade the node to achieve the lowest 10-year total cost?
