Sweden doesn't use much PON either. If a countries fiber build out started before gpon was released or got popular you likely continue a lot with point to point. There's a small drawback, TDM/A for the uplink, introduces some jitter but guessing it's not as bad as cable.
- martinald 7mo agoWell a GPON frame is 0.125ms. So the best jitter is ~0.125ms, but even if the entire upstream segment was saturated you'd be looking at probably 1-2ms at absolute worse case. The OLT will not allow one user to hammer the upstream badly like you get with DOCSIS. So it's really a non issue (XGS-PON is even better as more data per frame means heavy upstream 'clears' the frames quicker), IME consumer routers add more jitter themselves even with ethernet on the LAN side (and WiFi is a lot worse).
- Hikikomori 7mo agoNot great but much better than cable. I remember mmthe difference in smokeping as I switched from cable (very oversubscribed as well) to fiber.
