I recently had GPON installed at my house. They installed a Calix ONU inside, fiber thru the wall, and out to the overhead plant a few houses down. That part seems to work fine.
Now, I am rather bothered by lag, after the whole Puma6 shenanigans many have experienced in DOCSIS-land for a few years now, and I found some disturbing latency that nearly mimicks this in-action on my GPON.
They provided me with their low-end router, because apparently there is a shortage of newer dual-band routers in the market. I am running presently with an Actiontec C1900A ...
Disclaimer: I'm on Wifi, with both the 802.11n 2.4ghz Centurylink Router SSID, as well as with an EnGenius EAP1750H https://www.engeniustech.com/engenius-products/indoor-wireless-ceiling-ap-eap1750h/ and the results are the same; this leads me to rule out one or the other AP doing it. There is also the possibility my laptop is being strange, but at my last residence wifi never had these problems.
So far I cannot rule out the router itself as none of my devices currently have an Ethernet port (soon will, so I will test more in the upcoming days.)
Has anyone seen such cyclic jitter with GPON before?
This can also be probed with PingPlotter, as has been discussed in the Puma6 threads at length.
To get this graph yourself, with any of OSX, Linux, or Ubuntu in Windows/Cygwin, use MTR as follows:
mtr --curses somewhere;
