I’ve noticed a lot of medium to large FTTH providers are very heavily leveraged, all their fiber assets are pledged as collateral to get loans to build more. I would guess as BEAD rolls out, the copays are also borrowed money. My gut tells me if revenue fails to meet projections there could be a lot of loan defaults.
Which gets me to my question. In the popular fiber architectures, what parts are generic and can easily be used by a new owner? The glass itself would seem to be useful no matter what. But what about ONTs, OLTs, and customer prem equipment like routers? And other headend equipment like routers. What happens if a fiber equipment manufacturer like Calix goes though a bankruptcy or liquidation (thinking about the Cambium situation). Is this stuff all proprietary, closed ecosystem?

PON is definitely easier. Everyone (including me) likes Ethernet when they're new at it because it seems more simple and familiar, but PON is easier to manage. I'd keep Ethernet around for enterprise stuff, but bulk tier3 services are better off on PON. There was also a business case for Ethernet in a rural area where you might have small clusters of potential customers. You could add a 24 port or 48 port Ethernet switch a lot more cheaply than adding an OLT, but in the past decade you could also use Ubiquiti's UFiber in that same scenario. Or use XGS-PON where you can get long reach by adjusting min and differential range and minding your link budget. In that case you can look at it as the cost of adding ports on a central system vs the cost of adding a new point-of-presence. In other words, I think the tech based argument for Ethernet was at least partially wrong from the start, and the most compelling business case for it has evaporated. I also see Ethernet in open access networks where they put each provider in a VLAN and each ISP is just providing a router and customer service. I won't go on that rant today, but that model seems incredibly dumb in my eyes. -Adam On Mon, Oct 5, 2026 at 5:22 PM Nate Burke <[email protected] <mailto:[email protected]> > wrote: I don't have any PON in the field, only Active, but I'm curious why you're converting your active network to a PON network?
