has really got cheap.

On the other hand users are reporting issues with actually using
2.5ghz cable with this router in particular, halving the achieved rate
by negotiating 2.5gbit vs negotiating 1gbit.

Yes, it's very cheap and getting cheaper.
Since its price fell to the point I thought was cheap, my home has a 10 GigE fiber backbone, 2 switches in my main centers of computers, lots of 10 GigE NICs in servers, and even dual 10 GigE adapters in a Thunderbolt 3 external adapter for my primary desktop, which is a Skull Canyon NUC.
I strongly recommend people use fiber and sfp+ DAC cabling because twisted pair, while cheaper, actually is problematic at speeds above 1 Gig - mostly due to power and heat.
BTW, it's worth pointing out that USB 3.1 can handle 10 Gb/sec, too, and USB-C connectors and cables can carry Thunderbolt at higher rates. Those adapters are REALLY CHEAP. There's nothing inherently different about the electronics, if anything, USB 3.1 is more complicate logic than the ethernet MAC.
So the reason 10 GigE is still far more expensive than USB 3.1 is mainly market volume - if 10 GigE were a consumer product, not a datacenter product, you'd think it would already be as cheap as USB 3.1 in computers and switches.
Since DOCSIS can support up to 5 Gb/s, I think, when will Internet Access Providers start offering "Cable Modems" that support customers who want more than "a full Gig"? Given all the current DOCSIS 3 CMTS's etc. out there, it's just a configuration change.
So when will consumer "routers" support 5 Gig, 10 Gig?

Heat issues you mention with UTP are gone; with the 803.bz stuff (i.e
Base-N).
It was mostly due to the 10G-Base-T spec being old and out of line with the
SFP+ spec ; which led to higher power consumption than SFP+ cages were
rated to draw and aforementioned heat problems; this is not a problem with
newer kit.
It went away with the move to smaller silicon processes and now UTP based
10G in the home devices are more common and don't suffer from the fragility
issues of the earlier copper based 10G spec. The AQC chipsets were the
first to introduce it but most other vendors have finally picked it up
after 5 years or feet dragging.

Thanks, That's good to know...The whole SFP+ adapter concept has seemed to me to be a "tweener" in hardware design space. Too many failure points. That said, I like fiber's properties as a medium for distances.

another valuable featur of fiber for home use is that fiber can't contribute to
ground loops the way that copper cables can.
and for the paranoid (like me :-) ) fiber also means that any electrical
disaster that happens to one end won't propgate through and fry other equipment

Yes but as much as I like fibre; it's too fragile for the average household
structured cabling real world use case. Not to mention nothing consumwe
comes with SFP+ in the home space.

To add to Joel's point,
I can do my own catX cable runs and connect sockets/plugs to the cables, but I lack the tools for fiber-splicing... as cool as that would be it is going to be hard to justify multi-100s EUR for a splicer.. That still leaves short distance in the main computing area of an appartment/house, but I doubt that many consumers have a concentration high enough to justify the costs even there.
What I do see over here in Europe, with FTTH-roll out speeding up, is CPE that offer SFP/SFP+ cages for the WAN side though, SFP+ becoming more common since ISPs started to deploy XGS-PON (gross 10Gpbs bidirectionally, after FEC ~8.5 Gbps).
Regards
Sebastian
P.S.: I have not started jumping on the 2.5 Gbps or higher train just yet, none of my devices seems massively underserved with just 1Gbps yet (with the potential exception of a single link where >= 2Gbps would be nice since I am one cabe short and >2Gbps would allow to multiplex two 1Gbps connections over that cable).

The XG PON ONT units from Nokia/Huawei are coming with only 10G NbaseT
(usually singular port) only in the consumer access space. No SFP+
We have rolled out XG PON on the PON side to 70% of the country here (NZ)
over the last 2 years. Only a small % of that are actually making use of
the XGPON on the consumer side and retailers vary in offering it as a
service mainly due to having to truck roll a new ONT and lack of in home
10G kit on the market. But the access network is there.
Similar stories in other regions I know of that offer XGPon - lack of
consumer demand, lack of ONTs in the market that are suitable for
residential use.

Completely aside I have never got Cake SQM to work with connection's beyond
about a gigabit biderectional ; without loosing gigabits of throughput even
when running on beefy hardware. Has been a problem here for some time now.

Yes, ISPs are not that keen on distributing SFP/SFP+ modules, but there are some CPE that already come with SFP ports (AVM's Fritzbox 5530 Fiber, Telekom's Speedport Pro), IMHO only a question of time until these or their successors will sport SFP+ cages. I probably should add, that Germany (in unusual leadership in consumer-focus) actually has a "router-freedom" rule on the books, requiring ISPs to allow end-users to use any (compatible) router they like, and there is a current discussion about extending this right to choose your own also to ONTs; and at least in the enthusiasts' circles there seems to be a desire to use SFP-type ONTs to directly add to the router. (Personally I have no strong opinion on this, and will probably happily use my ISP's ONT once FTTH comes to my home, but I clearly see others already jumping through hoops to use SFP-GPON-ONTs).
>
> We have rolled out XG PON on the PON side to 70% of the country here (NZ) over the last 2 years. Only a small % of that are actually making use of the XGPON on the consumer side
So these are OLT's then that allow simultaneous GPON and XGPON? Any idea how much more expensive such OLTs are compared to either pure GPON or pure XGPON OLT's and do you know whether XGPON capability is something an ISP needs to pay for per connected customer (so some sort of per-user license)?
> and retailers vary in offering it as a service mainly due to having to truck roll a new ONT and lack of in home 10G kit on the market. But the access network is there.
Sweet! Sees like a reasonably forward looking deployment! That is something probably going to happen here as well, but since almost all CPE are explicitly rented out for an additional fee from the ISP (and shipping is charged extra) I do not think that the "truck-roll" part is going to be a big hurdle (not that any ISP here actually offers XGPON, but at least they are testing it).

Yah, I am not surprised, you need to invest heavily into the home network before > 1 Gbps access results in any noticeable improvement, and IMHO there are diminishing returns for adding more "bandwidth" to a link. E.g. I am currently on a 100/40 plan, so a far cry from GPON's local max of 1000/200 let alone XGSPONs yet unkown rate-plans, but I rarely think "if I only had faster internet access" (I will still switch to FTTH ASAP, since I would like not having to bother/monitor the DSL link parameters to check for errors and changes in sync rates).

Sebastian

Mmmh, I guess our approach at traffic shaping does not scale well at those speeds. Maybe this could be fixed with larger batching?
I think it might be worth trying to switch to simple.qos/fq_codel and set a somewhat larger burst/quantum duration in defaults.sh, then disable BQL on the NIC and configure a beefy txqueuelen on the interface. This might help making SQM limp along to higher rates. If that would actually work, we could try to see whether we can make cake learn coarser batching ("bursts" and/or quantum) at high rates (but I did not check what cake does internally, it might already do this, @jonathan?)....

I fear the problem is rather the lack of multithreading. I have a fairly
beefy 8-core ARM box for my main router these days, and even that can't
forward at a gigabit on a single core. There was a bug in the HW
configuration so all traffic was sent to a single core, which resulted
in 50+ms of bloat and traffic capping out way short of a gigabit. Now
that it's fixed and traffic is mixed over all eight cores I have smooth
sailing and no bloat. Thankfully I don't need to shape, so I'm just
running straight mq+fq_codel on the physical interface....

Leviton has wallplates for fiber, and the tools for fiber are cheaper than the tools for CAT6.
Pulling fiber through walls hasn't been a problem for me. No more than pulling CAT6.
I know I shouldn't kink or pull fiber hard. In the worst case, I pull light flexible conduit through walls with pull strings so I can add arbitrary numbers of fibers. This is good practice, anyway (for wires or fibers).

This is what I recommend to my friends/family when they talk about remodels
and having the walls open: Run 1" flexible conduit to any place that you
think you'd want to run a cable to, while the walls are open, it's cheap
and easy then, and a massive reduction in headaches later on, if you find
you want to replace coax with cat6, or cat5 with fiber, etc..
