Most innovative and disruptive (and generally just profoundly interesting) company that hardly anyone knows about in the grand scheme of things.

Seems to have only basic usefulness as a diagnostic tool.

> Instantly tests SFP and QSFP module health, including Rx/Tx power.

Most SFP modules will fail due to heat, like LED bulbs. So an instant test is of course instantly useful, but not indicative of production-use SFP health.

As a programming tool, of course it's awesome.

Of course, in typical ubiquiti fashion, it's out of stock with no way to backorder.

some context that's perhaps not obvious to non-networking people: essentially all networking hardware above 1G doesn't have rj45 or fibre ports in it, it has holes that you put modules in, "SFP+" modules for 10G, "SFP28" for 28gig networking, etc.

most manufacturers of devices - the things with the holes, NICs, switches, routers - make their devices only officially work with modules that claim to be manufactured by that same manufacturer. so, you can either buy modules from that manufacturer, or buy modules from some other company (e.g. fs.com, 10gtek) who programs the modules to claim that they are from that manufacturer. "officially" can mean anything from "we won't help you if you open a support case" to "the device will make a whiney log message on boot if it's not one of our modules" to "it simply doesn't work unless you hack an EEPROM on the device".

this is somewhat annoying, since it means you need to buy specific modules for specific devices, you can't just keep a pile of SFP+ 10G-LR modules around, you need some "Intel SFP+ 10G-LR" and some "Cisco SFP+ 10G-LR", etc.

so, these third party manufacturers of the modules, like fs.com and 10gtek, will also sell you programmers for the modules, which lets you change what manufacturer the module claims made it. these programmers have been, historically and hilariously, tied to the actual manufacturer of the modules! so you can buy some 10G-LR SFP+ modules from fs.com and a fs.com programmer to set make some "Intel" and some "Cisco", but if you buy some 10gtek 10G-LR modules, you would need to buy a 10gtek programmer.

~so, this device that Ubiquiti has made is the meta-programmer - it can apparently program any module, from any actual manufacturer, to claim to be made by any manufacturer.~

edit: the post seems deliberately confusing - what they are actually selling is a device that can re-program Ubiquiti SFP+ modules by copying the manufacturer code from another SFP+ module that you insert into the programmer. so it's the same as what fs.com and all the other sell, but Ubiquiti's is ~1/10th the price (e.g. https://www.fs.com/uk/c/fs-box-3389).

Minor pedantic correction: 2.5gbit, 5gbit and 10gbit RJ45 is getting more affordable and more common, and for short runs should run over CAT 6 and CAT 6a fine, and plenty of reports it does ok on short runs even on CAT 5e. With devices like the USW Flex Mini 2.5 at ~50-60 EUR / USD, you can affordably outfit your home for higher than gigabit speeds without rewiring everything with new CAT cable or fiber.

Over here in NL we now get more and more access to >1gbps speeds, the office of my small business for instance has a 4gbps connection, and the ISP offers up to 8gbps on a standard consumer / small business package. We're in the process of upgrading our gear to take advantage of that. With WiFi 7 we've seen some real world throughput speeds of 1800-2000mbps going through a Ubiquiti U7 Pro straight to the ISP supplied router.

I wasn't really keeping up with networking gear, so I was pleasantly surprised when I looked into this stuff recently and figured out the gear has just magically gotten better and running 2.5gbit everywhere is surprisingly easy.

Something nonobvious to consider, 10G copper/RJ45 SFP modules run hot, to the point where our Mikrotik switch's manual mentioned that we could use them, but they strongly recommended only populating every other port, if we did. Heat wasn't a problem at all with the fiber ones.

Still, compared to the SFP+ gear it's ridiculously overpriced. NICs are <$20 on ebay and an 8x10G port managed switch is $120 on aliexpress.

> Over here in NL we now get more and more access to >1gbps speeds

Same in France, yet the main "geek" ISP (free) has an 8Gbps symmetric ISP router with a 10G SFP+ cage for full bandwidth to the LAN. RJ45 ports are 2.5G.

And it's hard to fault them, as customers that are likely to even hardwire stuff to the router and moreso at 10Gbps are usually enthusiasts that do prefer SFP+ due to the abundance of hardware on the used market. Oh, and their team designing the router are a bunch of nerds that most likely all have a 10Gbps network.

There’s an ISP in Switzerland offering 25Gbps, they provide a Mikrotik. They’re called init7.

Yup, that's pretty nice. I sold a couple of XXV710s to a friend that moved over there.

The FS-Box lets you pick from a list of manufacturers and serial numbers. Does this only do cloning from another physically inserted SFP?

Just bought an SFP+ module that works with Cisco, Dell, Juniper but won't work with Unifi. Is this supposed to test all generic modules even the cheap Chinese brands ?

WTF is 'SFP'?

Small Form-factor Pluggable, a common optics format for 1 to 25Gbps networks. See the wikipedia page: https://en.wikipedia.org/wiki/Small_Form-factor_Pluggable
