It describes the roles of the OLT, passive optical splitters, ONTs, and the customer router or gateway, including how providers share feeder fiber among subscribers and provision authorized ONTs. ### Source excerpt If you've spent any time looking into fiber Internet, you've probably run across terms like GPON, XGS-PON, OLT, and ONT. These are all parts of what's called a Passive Optical Network, or PON. Most residential fiber providers use PON because it lets them connect alot of homes without having to pull a separate fiber from ...

It proposes neutral last-mile fibre infrastructure, allowing ISPs to compete on service quality, and discusses contention in PON and AON networks. ### Source excerpt The recent debate around Airtel's priority 5G generated plenty of noise. Personally, I'm not a fan of it either but Airtel and Jio are private companies. Their job is to maximise shareholder value, not to maintain market competition. The real question is why competition remains so limited. And by competition, I don't mean another mobile operator. I mean fixed-line broadband. Two long-standing problems continue to hold India's internet ecosystem back. 1. Every ISP builds its own last mile In the early days of FTTH this was understandable. In 2026, it feels increasingly wasteful. At my home in Haryana, around a dozen FTTH providers are available. The pole outside carries 14 fibre cables from different operators -- all solving the same problem independently. The last mile isn't where ISPs differentiate. Fibre from ISP A isn't inherently "faster" than fibre from ISP B. The real differentiation is in the network behind that fibre capacity, routing, peering, resilience and customer support. Yet every provider continues deploying duplicate infrastructure. Even Airtel and Jio increasingly push Fixed Wireless Access because expanding FTTH remains expensive. Instead of parallel deployments, we should encourage neutral last-mile infrastructure. A small number of regulated fibre providers could deploy high core count cables, while ISPs lease strands and compete on service quality rather than digging the same streets repeatedly. This will also help in fixing streets which look quite ugly with excess fibre routing in all directions. Earlier this year, Stefan Schüller published an excellent article, The Free Market Lie: Why Switzerland Has 25 Gbit Internet and America Doesn't comparing broadband infrastructure in Switzerland, the US and Germany. It's well-researched and provides useful context for many of the points discussed here.I do disagree with one aspect of the article - its comparison of Passive Optical Networks (PON) and Active Optical Networks (AON).

It covers obtaining an ONT and PPPoE credentials, configuring VLAN 35 and PPP, setting up iptables, and providing DHCP for the local network. ### Source excerpt Orange FTTH on a custom router Here in Poland, Orange has a decent FTTH offer - less than $16 for 300Mbit down, 50Mbit up. People reversed it over the years, most impressively Pierre Kim in 2016: Recently, it has been possible to replace the router the provider gives, called "FunBox 3.0", with a custom one. There are couple of reasons for that: - My understanding it's impossible to get a stable IPv6 on FunBox 3. - FunBox is proprietary and evil.
