What use cases are there for residential (or even most business) connection to be 25Gb/s (or even >10 Gb/s)? Are there 'practical' application for homes or offices to have this much?
At $WORK we have both 10 Gbps to both our office and our DC, and we don't come close to saturating that.
There's really only so many Linux ISOs that you can download at home.
(I'm not "against" having it, just curious on possible uses.)
A 5 minute download vs a 50 minute download is a totally meaningful difference in quality of life. It might sound crazy but a top end gaming rig can definitely take advantage of that 10G connection.
Unless something has changed in the last year, you’ll also have a lot of difficulty getting 10gbps of download speed from steam, let alone 25.
For instance: who in their right mind would have built Netflix in 1992?
Bandwidth is like speech. Once you’ve provided the basic framework you should have the right to as much or as little as wanted.
We don’t limit speech of some people that don’t talk as much and expand it only for those that talk a lot. That would be crazy.
If there is no real use , why spend for that kind of gear ?
I’m sure all the folks that have had to tear up 100Mbps LAN cables wished there was 1000Mbps cable in there instead.
I'm asking: why even get the 25Gig service over the 10Gig? What are you doing with a 25G down/uplink that you cannot accomplish with 10G?
The 1gibt service they have now is cheaper and intended for "regular users". It's now CGNAT and comes with a per-configured router. [2]
CGNAT? As in: The provider walls in customers behind a NAT - and customers can't forward their own IPv4 ports? That CGNAT?
Asking because that seems like a cruel restriction on 25Gbps upload.
Yes. But I'm asking: what is the need for it?
If you want and are willing to spend the money go ahead. But I'm asking for the use-case.
I used my symmetrical upload for work. I'd copy virtual machines home to fix and then copy them back. I hosted VMs that I used as a template. I'd host huge ISOs so I didn't have to carry install DVDs with me.
Past that, it's pretty sweet to be able to access every bit of my home network as if I were there.
But then I moved to an area with one internet option, a cable ISP. I now drive a LOT more than I used to.
Ever transfer a file more than a few hundred gigs? This makes that take less time. Even if I’m only pulling down files at 1800 mbps Ive got plenty of headroom for everything else.
Using a mapped remote drives for actual work, especially with multiple remote workers. (WFH kind of blurs residential/business use case distinctions.)
Not just the bandwidth but also the latency of fiber vs copper. With sub 10ms ping times and you're pretty much there.
You're saying fiber's low latency (within a metro area) is more tied to it's carrying capacity as opposed to it's transmission nature. You're correct. Maybe also pedantic but certainly correct.
MTP, like TCP but more squishy.
The book entangled-life was also a great read [1]

My various jobs in recent years is to run HPC data centres: a little while ago one with 12PB of total storage (along with lots of Ceph storage for ~300 on-prem, private cloud OpenStack instances), a more recent one had about a thousand GPUs (our power usage was high-five digit kWh each month).
Whenever I looked at our routers/firewalls, we never came close to saturating 10Gb/s even with all data sets we dealt with.
I believe that a synchronous clock is a given for broadband.

What does going to 10G, let alone 25G, get you? Are you really planning on 70-100 4K simultaneous movie streams on 10G, or 160-250 simultaneous streams on 25?
