I'm in a top 10 most expensive city in the world (Canada) and the best I can get for $50 is 80 Mbps (and even that is only available as a promotion that you can't get by simply going to the ISP's website and buying a plan).

Have you looked at smaller ISPs? I live in rural BC and I'm was able to get 80Mb for $35 using a no-name internet only provider with no contract. If I went with one of the big cable companies I would be paying at least double for the same thing

i signed up with one of the small ISPs in rural Canada. month after, they were bought by Rogers... :-(

On behalf of all tech-minded Americans, I would like to say... I hate you. I just got a notice in the mail that my ISP is "upgrading" their network so now I can pay $200 USD/month to get a whopping 2gbps, which I actually thought was pretty amazing until I read your post. So, thanks. In all seriousness, congrats! You made a good case for why one would need that much bandwidth. Also, we need to catch up here. :)

One thing most people ignore: the prices these days for many thing don't have a direct correlation with the cost, but with how much people are willing to pay. This is happen especially in quasi-monopoly situations, like housing and internet services.

For example I have 3 Internet connections at home that I pay ~ $30 in total, from 150 Mbps to 1 Gbps. I think the 1 Gbps is ~ $12/month, it is so cheap because there are so many options and I can afford to keep all 3 for redundancy (1 is a 4G mobile data capped at 200GB/month, it works even when there is a power failure in the entire neighborhood).

But if there is no variety of options and no competition, then price is high. From what I read, most ISP in USA are squeezing as much as they can from their clients, sometimes to ridiculous levels.

> Can you share, at least vaguely, what was your work? We work with gis/satellite data. Nothing groundbreaking technically, but we aggregate it into products that are useful for social science researchers who aren’t comfortable with or don’t have the computing resources to use this data by themselves.

What exactly about gis/satellite data required such an insane uplink?

I can think of two things. Large time series data for large areas with a lot of attributes like temperature or other atmospheric data or a huge amount of point clouds or comparable 3D Data.

Mikrotik makes a whole bunch of 10G hardware. The 8 port ones are fanless and have a heatsink on the back, and the 16 port model has a fan that only gets switched on when needed. I have one sitting behind me and it's been off all day. It's also easy to open and replace the fan with something less noisy. Just remove a few screws, it's a standard size with a normal connector on it. There's also big external heatsink so…

I had issues with 10G copper SFP+ modules even when there was only one installed in the switch (Mikrotik CRS305-1G-4S+IN), the other modules installed being DAC/fiber. I got random disconnects I could not attribute until I checked the switch logs - the module was shutting down because it was reaching >90C when the ambient temp was 26C. I had to add a fan.

Not all transceivers are created equal; some need more power (and then dissipate the heat), some are satisfied with less. Some can do only 30m distance, others will run over 80m distance.

The Mikrotik ones (S+RJ10) are based on Marvel chip and they are the more power hungry / run over 30m only variety. On the other hand, they can negotiate 2.5G or 5G if necessary and support a proprietary protocol to tell the switch about it, so you will that in SFP+ properties.

As I have written in the sibling comment, I have good experience with BCM84891-based transceivers. CRS305 can handle two (still not next to each other, obviously).

Firstly … 25Gbit symmetrical … WOW. Secondly - as a person living my whole life in IT - both passion and professionally - I have no idea what would 25Gbit be good for. I’m currently paying about $80 for symmetrical 1Gbit fiber and have the option to upgrade to 5Gbit for about $180 but it seems so pointless. Here is the reasoning behind my grumpy opinion: 1.

> Back to original question and with genuine curiosity - what is 25Gbit for???

From a switch perspective, it makes more sense to carve out 4x 25G ports vs 4x 10G ports if you have 100G switches. In a single rack unit you can fit ~32 100G ports, which can then be broken out to 128x 25G ports. That’s more port density than a 1U 48 port 25 switch/line card.

I’ve never heard someone call their own country a “third world country”. Out of curiosity, which country are you referring to?

This is term is commonly misused as it originally referred to countries beyond the Cold War's NATO/USSR denominations. Today the parent likely refers to a country in the global south or a "developing" nation. I'm from what used to be a third-world country in the strict sense of term, I'd now refer to my country as a country in the global south.

What’s the “global south?”

I don't get the "lack of use case" comments. There is no use case TODAY. But what does having 25Gbit fiber enable to be built TOMORROW? Shared photorealistic VR spaces immediately come to mind.

Exactly, I’m wondering the same thing. Like, who cares “why”. The same reason Android supports a USB mouse. We build it because we can.

Now if they can lower the cost of the network equipment that would be ideal.

Cat5 can be capable of multi-gigabit over runs less than a couple hundred feet. Don’t count yourself out yet.
