I'm not sure if I should buy the Mikrotik S+RJ10 for about 755kr.Or if I should buy fs.com's 549kr module, then throw in some of their cheapo DAC cables to hit the 799kr free shipping limit.

I don't know if they handle Norwegian VAT or not.International stores can handle it under a somewhat recent agreement, so buying stuff online is just like shopping in Norway.But fs.com doesn't specify anywhere whether the prices are excl. VAT or incl. VAT for Norway. Even though the prices seem to be in manual NOK amounts rather than converted from EUR or something.

Besides their VAT handling. I just don't know how much the quality of an SFP+ to RJ45 module matters. I haven't ever worked with SFP+ before.We have SFP with gigabit fiber at work, but even at work we have no 10 Gbit.

I /want/ 10 Gbit at work. Because currently there's a stack of three HP switches with 4 SFP ports each in our main building, and the 8 fiber links going to our other buildings are just plugged into whatever SFP port was free on those.Which really sucks because it means entire buildings that might house tens of people, often 50+ are bottlenecked by a 1 Gbit fiber.I've wanted to get a distribution switch with SFP+ ports to 10 Gbit the buildings. Not to mention that our three 48 port switches just use regular 1 Gbit ethernet cables as trunks between them. If I could SFP+ DAC them with 10 Gbit between each switch so that huge chunks of users weren't bottlenecked to 1 Gbit towards the file server, that'd be great.

@wolf480pl Well they pay attention since they report it in the UI and CLI afaik.I don't think they give much of a shit though. Blocking SFP modules based on vendor is mostly a thing the enterprise giants like Cisco, HPE and Dell do.

@quad form what I've heard, the exact electrical and thermal specs vary between vendors. And on top of that, some vendors check the vendor ID of SFP modules and refuse to work with third party ones.fs.com can fake any vendor ID (you choose when ordering, or reprogram yourself using their very expensive tool) and IIRC they try to make their modules extra tolerant of varying thermal and electrical specs, but I haven't tried them myself.Maybe @nihl or @marek will be able to tell you more.

@wolf480pl @nihl @marek I think Vendor compatibility will be fine. I doubt Mikrotik hardware gives a shit, kind of like Ubiquiti tends not to.But I do know that SFP modules (and probably + too) tend to be very sensitive to voltage and sometimes run overly hot, so quality between brands can vary a lot.

@wolf480pl @quad @marek I've got a bunch of transceivers from fs.com (and fiber cables as well), for Intel and Chelsio NICs and an Arista switch. They indeed make custom modules with the vendor ID your hardware might require (it happened at a previous job when trying Dell transceivers in an Intel NIC, the NIC's firmware error'd out). As far as I can tell they're very decent quality, after a few years I have yet to see one fail.

@nihl @wolf480pl @marek Do you only have experience with fiber tranceivers?I'm looking mainly at a 10GBase-T RJ45 module for my NAS, possibly with some DAC cables as trunks between switches. I've heard some of them heat up like infernos.I'm familiar with the vendor mess from regular non-plus SFP at work. Although I've only really seen enterprise nutjobs like Cisco, HPE and Dell care about it. "Prosumer" stuff like Ubiquiti is at least mostly flexible I think. And Mikrotik definitely doesn't give a shit.

@quad @wolf480pl @nihl the 1G RJ45 SFPs we have got do run warm, and I saw some users stick heatsinks on their 10G ones for a bit of extra dissipation! Maybe what I was worrying about compatibility is fixed in newer revision of S+RJ10 — my memory on this is hazy, and not finding much in my notes. Have asked a colleague who I seem to remember had this problem.

@marek @wolf480pl @nihl Thank you for looking into it. I have heard the Mikrotik's S+RJ10 runs hot at least. Mikrotik themselves recommend only using it in switches with fans and not passively cooled SFP+ switches. Unsure if this is something specific to the S+RJ10 or if it's worse than others.I'm planning to order the switch and SFP+ module tomorrow.The switch I'm ordering does not have fans. But it has no fan header on the board, so adding one afterwards isn't particularly easy either. Since it's about the only SFP+ switch in my budget I'd rather make sure it's not going to end badly.

@quad @wolf480pl @nihl we have hundreds of FS optics and DACs — our approach has been "buy FS and you can afford spares"However I also know one network who had major problems with 40G QSFP modules which had high error rates on low temperatures(!) when the DC aircon was set wayyyy cold. Temperature was still "within spec" according to FS' optics, but definitely was causing high BER.

@marek @wolf480pl @nihl Sure sounds like you know your stuff. I've barely used some 1G SFP at work. This is my first time dabbling with 10G. The combination of the only SFP+ switch in my budget being fanless, people saying the modules run hot, and Mikrotik recommending the S+RJ10 is used only in actively cooled switches simply makes me a bit nervous.Since a ~$300-400 purchase of network gear is a considerable chunk for a private individual.

The CSS is cheaper but someone on my instance who runs a WISP with lots of Mikrotik recommended I stick to CRS over CSS if possible.They already have a fan cutout in the case. There's just no fan there. Really annoying they didn't just give me a fan head too.

The CRS is an L3 swich (but performs like hot garbage on L3. So mostly buy it for better CPU, RouterOS and console port as far as I understood it)

@marek @wolf480pl @nihl I notice that FS has multiple modules though. One "up to 30m" and one "up to 80m".Not sure if there's any other difference, but i only need like a 1m patch. My NAS has a 10 Gbit RJ45 port I want to make use of and there happens to be a replacement for my Cisco SG250-26 which has SFP+ ports:

If you don't mind soldering the thread marek linked ends with someone who apparently got a fan running just by connecting it to the two free holes next to the barrel power connector (unless I see these pictures wrong), that's pretty clean.

@quad @marek @wolf480pl That's understandable. Another option would be to get/make USB-3/4 pin cables and use them to power one or multiple 5V fans connected to a machine near the switch, they're not very hard to build and it's much less stressful than tinkering with the insides of a brand new switch.

@quad whenever I've bought from FS, it's been a case of "where is it shipped from?"Where we had WDM muxes manufactured and shipped from China, we had to have an EORI number to be able to import them into the UK, and be charged and claim back the duty and VAT.Where it was in stock in Germany, it was shipped with "EU VAT nil" (i.e. shifted), so we had to account for it as "goods from the EU" and claim and charge VAT on the optics appropriately.All change in January 😠

@marek Norway is not in the EU so it's even more complicated for us. Instead companies need to be under a specific agreement to process VAT. Many companies are but tend to be bad at informing about it.In that case VAT will be applied to the prices and when you order they can ship it from wherever the fuck they want to as long as they include the VAT reference on the package.Hence for example if I order a computer on lenovo.com, it gets charged with VAT and ships trouble-free from china.So the worst is when a store just does not specify if VAT is included or not. If it isn't, you pay the VAT in a separate bill, but the worst is that there's typically like a 30 EUR charge from the courier to handle the VAT declaration too. So you can order a 10 EUR doodad and when it arrives you get a 32.50 EUR bill for it.

@nihl @marek @wolf480pl Quite simply the ones with PWM in their name are PWM regulated. And the ones with FLX in their name use 3-pin and are voltage regulated.Of course these crappy USB to 5V fan adapters probably don't do either.

@quad @nihl @marek Without a temperature sensor, I think best you can get is manual voltage regulation with a potentiometer. Though that means soldering.

@quad indeed, this is the situation I fear the UK will be in — but many businesses are mostly unprepared for, because there's been crap-all communication from government until the last couple of weeks that "No Deal" is the likely outcome from January 1st and what that might entail 😠

@marek I mean at least the UK has the advantage of being a far more populous country.With Norway most people don't bother doing the paperwork since the only potential consumer audience is about 6 mil people. And for a niche product like this, probably less than 100k because I think there's separate procedures for business sales.So most companies will not handle VAT for Norway, making stuff hella expensive to import. Simply because they forget we exist, forget we aren't in the EU. Or just determined that it's not worth the effort to make like 5 small sales a year to such a small country.

@marek For example store.ui.com ships almost everywhere. Including a "Europe Store" that ships to Europe... except for Norway.It ships to all our neighbors. Sweden, Finland, Denmark. But not Norway. If you want to buy Ubiquiti stuff in Norway. Sorry, you can't buy straight from them.The 189 EUR Gen2 switch? Yeah it's 300+ EUR in Norway, cough up. You have no choice but to buy through specialized stores with high markup.

@marek Just to rub it in. store.ui.com does ship to both the UK and to Switzerland.But Norway? No we're so tiny so why bother. Switzerland might look smaller. But their population is larger and they're logistically easier to ship to.For Norway a ton of companies just made the cost-benefit analysis of "No, we've just decided that our products will not be available in Norway"

@nihl @marek @quad btw. I looked at some YT videos of Noctua A4x20 fans, and it looks like they don't whine even at max RPM.And it kinda makes sense - they only go up to 5k RPM. So maybe you can first try out without speed regulation, and only add a potentiometer if it turns out necessary.

@wolf480pl @nihl @quad might be worth popping the lid of the switch and sticking heatsinks on the SFP+ cage on the inside, to help dissipate even more heat, as there's a much larger surface area inside than out

@marek @wolf480pl @nihl Fair point. I'm only going to be doing a single SFP+ module too. If I use the other SFP+ port it's probably going to be a DAC to another switch. So just putting some heatsinks on it might be enough.

@quad @wolf480pl @marek Shitty measurents done real quick: it seems to be around 14mm, and the module fits pretty snuggly in the NIC. The part of the transceiver that sticks out is slightly larger, and that's probably even more true for RH45 ones.

@nihl @marek @wolf480pl I'll probably stick one on the inside. I don't have a switch at work I can open without voiding a warranty, can you measure how long the SFP port is internally? How many 14x14 heatsinks would fit on it internally. I'm guessing like two and half

@marek Oh I can get it.Like always, from stores that import/ship from Sweden. Just at near double the price. CDON has all their warehouses in Sweden as far as I can tell and Proshop has it listed as "remote stock" which generally means ships from outside Norway, either Sweden or Denmark.I'm not joking when I say that our neighbors in Sweden get everything that we don't.

@quad @marek @wolf480pl on that NIC there's 42mm of free space, I imagine it's pretty much the same in a switch so you could stick 3 heatsinks (with at worst the last one hanging over half a millimeter).

@marek @wolf480pl @nihl Luckily I have fiber.I'm in a tug of war with my ISP along with some others on a Norwegian forum. We're playing cat and mouse where I first figured out that you need to use VLAN 10 on WAN. Then suddenly you need to clone your ISP router's MAC address, and now it seems like some subscribers might have to send a DHCP client identifier as well to get an IP.

@marek @nihl @wolf480pl But luckily their setup consists of a fiber to ethernet media converter mounted on a wall, then a standard Ethernet cable to the WAN port on their router.So as long as we can keep up with whatever the fuck settings we need on the WAN port we can make it work.

@marek @wolf480pl @nihl I had nothing. I hat an Ethernet cable from my landlord on a 25 Mbit fiber plan I think it was. So everything was double NAT'ed and whatnot.I convinced him to let me drill through his wall and then made the ISP splice a fiber run from his point to my apartment and now I have 300/300 Mbit fiber.Though I wish I could get a static IP but the ISP won't respond to questions about that. Even better would be if I could rent a /29 or something. But that's probably not happening either.

@quad @wolf480pl @nihl given the paucity of IPv4 addresses, they're probably CGNATting you to squeeze maximum value out of their address allocations for residential customers — maybe offering static public IPv4 only to businesses?If v6 worked for you, that'd be a big improvement… but otherwise I guess you have to make a tunnel to somewhere for a public IPv4 address? :(

@marek @wolf480pl @nihl Oh no. I do have a public IP now. My internet situation is pretty nice since I managed to get my own router to work.It's just that my ISP refuses to respond to any technical request whatsoever. I want a static IP at home rather than dynamic. I'm even willing to pay 10-20€ extra per month if that's what it takes. Even better would be if I could also say get a /30 IPv4 subnet routed to that static IP to. I'm willing to pay full prices for that too. Which is about 40-50€/month.Or at least 149kr/month (~14€) for static IP and 499kr (~45€) are what the ISP charge me at my workplace for those services.I'm willing to pay full business prices, essentially double their monthly revenue off me. But they won't even give me a "no". They just ignore all my E-mails. Won't even give me a canned "We do not provide this service for private individuals" response.
