Provided by Telekom Deutschland. This is a 2.5 Gbit/s DOWN, 1.25 Gbit/s UP shared GPON. The Fiber terminates in our rack cabinet. CPE is a "Telekom Glasfaser Modem 2", behind is a Fritzbox 7530 AX which does the PPoE Dial-In.
Interesting is the first-hop latency which is 1.4ms in the best-case. I don't have any explanationf or the packet loss.

Both the ADSL Line and the FFTH line terminate in the same building and seem to use the same POP. The first-hop looks to be the same. So I did some mutual pings.
This underlines the first-hop response time of ≈ 1.5ms for the Fiber and ≈19.8 for ADSL. I don't have any explanation for the packet loss.

Provided by Vodafone. CPE is a Fritzbox 6591 Cable . Downstream uses DOCSIS 3.0 only, Upstream uses 1 Channel of DOCSIS 3.1 and 4 Channels of DOCSIS 3.0. This line is in the same building as the GPON Fiber line.
Unfortunately, this connection needs a reboot of the modem every ≈ 3 weeks, as the upstream direction will loose the 64 QAM Modulation and Fall back do 16 QAM. The line seems to be disturbed in the rf spectrum, but the customer service won't do anything about it.
The modem gets a static IPv4 without CGNAT. I consider the first-hop latency to be 7.4 ms

Test location is a single family home in département 38.
The ISP is Orange (ex. France Télécom).
The CPE is a orange livebox 5. The monthly package includes 2 Gbit/s DOWN , 600Mbit/s UP with no data cap and is 50€ (2022).
The speed tests needed multiple devices, as there are only 1 Gbit/s Ethernet Ports on the router. We were able to saturate the 2 Gbit/s DOWN , 600Mbit/s UP simultaneously (measured with iperf over 120 seconds).
Measured with mtr . Started roughly after midnight and lasted for 9000 seconds, i.e. the least busy time of the day. The router does dual-stack. Measurement PC is attached via cable. WIFI disabled.
The first-hop latency is 1.2ms in best-case ipv4. What I find interesting is that ipv6 seems to be consistently slower, even the best-case first-hop latency for ipv6 is 1.9ms and thus 0.7ms slower than on ipv4.
End-to-end however, the average is nearly the same, and stdDev is lower for ipv6.
Using an WAN Latency Estimator gives the lower limit at 9.6 ms (600km), so roughly 2/3 of the latency a attributable to the link itself, and 1/3 to processing and devices.

I personally think that Interleaving is the problem. After a Line Reset from ISP, it feels great for 1-2 days (like ADSL) then it is worse than before. After I got sick of all the tuning bullshit and pseudo-tweaks for networking, I switched to console gaming to get the same environment than others with console. So the only tweaks I can try are on router base. There I tested also several things like Draytek Modem, Fritzbox etc.
Sadly no ISP allow to disable interleaving -.-
