Brownfield node upgrade strategy

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 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?
