 emily | this is all I'll say | 12:14:48 |
| emily | I just searched "10g sfp switch" on AliExpress | 12:14:55 |
 matthewcroughan @fosdem | the SFP setup is a bit harder, because then you have to run fiber to the wall plates | 12:15:00 |
| emily | 8 SFP+ ports, $95 | 12:15:03 |
| emily | that's a lot of SFP+ buying budget | 12:15:11 |
| matthewcroughan @fosdem | and I'm not sure SFP wall plates exist, so I'd have to DIY that | 12:15:14 |
| matthewcroughan @fosdem | I mean, both can be done at a low cost | 12:15:28 |
| emily | it's genuinely not even a little bit harder in any way | 12:15:28 |
| matthewcroughan @fosdem | I could get both, and then have all the connectivity options | 12:15:37 |
| emily | once you put the copper SFP+ modules in, you have the exact same interface as the thing you want to buy | 12:15:39 |
| emily | given that, there is no way it can complicate any plan… | 12:15:50 |
| matthewcroughan @fosdem | Ah right I forgor | 12:15:59 |
| matthewcroughan @fosdem | only one side has to be SFP | 12:16:06 |
| matthewcroughan @fosdem | that was the problem with my thinking :D | 12:16:15 |

the SFP setup is a bit harder, because then you have to run fiber to the wall plates No what the fuck are are you on | 12:16:35 |
| magic_rb | Unless you plan to have the switch in the wall | 12:16:47 |
| magic_rb | Anyway | 12:16:48 |
| magic_rb | Ive better stuff to do | 12:16:51 |
| matthewcroughan @fosdem | Well in the case of fiber both sides have to be SFP | 12:16:52 |
| emily | like if you want to spend more money for a less flexible setup you can | 12:16:51 |
| magic_rb | Bye | 12:16:51 |
| emily | but I don't know why you would | 12:16:54 |
| matthewcroughan @fosdem | No it makes sense now that I remembered on rj45 only one of the sides need to be SFP | 12:17:23 |
| matthewcroughan @fosdem | You can understand why I wouldn't want to bother the end-user with SFP | 12:17:36 |
| matthewcroughan @fosdem | do those sfp only switches support negotiating lower data rates like 5G too? | 12:18:05 |
| magic_rb | It depends on the sfp module not switch | 12:18:33 |
| matthewcroughan @fosdem | So if I plugged the rj45 side of a 10G SFP cat6 setup into a 2.5gbps port on my laptop, it's not going to work unless the SFP I have chosen supports "negotiation" | 12:19:27 |
| emily | well, it can depend on both | 12:19:31 |
| emily | some SFP+ modules will do 10G on the host but negotiate multi-gig | 12:19:39 |
| emily | some of them will negotiate slower rates on the host too | 12:19:47 |
