Hell of a price to buy a 25Gbit network card for your machine though to make use of it...300chf approx
10Gbit cards are still expensive enough (200chf for a USB 10Gbit dongle) - maybe as this becomes more widespread the 10Gbit cards will come down in price at least.
More expensive than that. Much more. Plus there is no way that one can process 25Gbit/sec of data on a single machine, at least not at home. Maybe in the data center or some small business with heavy, concurrent data downloads.
This whole 25Gbit/sec offer for private customers is just a marketing bs or rather a taking a p..s at the 10Gbit bs XGSPON offers from other ISPs. People just fall for the numbers, bigger the better, even if they have no slightest idea on what to actually do with it...
There's plenty of refurb 25Gbe Mellanox'es on ebay for around $100-120. No point whatsoever in dropping high 3 - 4 figures on brand new latest and greatest gear. This stuff is actually fairly old and has been around for a decade or so in datacenters, the high end is 200-400Gbe now.
Modern NVME SSDs coupled with a decent processor can easily saturate that bandwidth from a single machine. What would you currently need it for at home besides the occasional torrenting is a good question though
Yeah, true, buy you cannot plug in a a 25GbE cable into the optical socket ;-) So you need something in between, router, cabling etc. Even with a budget, refurbished stuff, it'll get expensive.
Yes you can - you need a cable with an appropriate SFP module, "25G SFP28 BIDI LR, 10 km, TX1271/RX1331 nm" is what init7 wants , and you can plug it straight into your 25Gbe card's SFP slot. Router is not needed if you need to connect only a single machine to them.
That'll be CHF 777 incl. VAT extra - and for that price you only get just two 25G ports.
SFP module and refurb mellanox would be much cheaper. I'd spend the rest of CHF 777 on a decent server/workstation to put it in
I only got the 10gbe fiber recently and I understood that there's no point getting anything above 2-3gbe. Past this speed, all other component (card, HD, port etc..) are the limit.
Adapting all hardware to match the top speed would cost a fortune and with no noticeable difference in use...
>1gbit ports are still relatively uncommon in consumer products but they're not that expensive. The stuff has been around for a long time in datacenters - you can source second hand equipment pretty cheaply, especially 10gbit fiber(SFP) variety. 10gbit copper is newer and on the expensive side but old fiber equipment is pretty cheap.
Speak for yourself. I run some web scraping operations for a side gig and actually can fully utilize all that bandwidth. If only i had enough disk space which is a bigger, more expensive problem
