John213 Posted October 1, 2021 Share Posted October 1, 2021 Hello My equipment: NIC: Asus XGC-100F RJ45: 2x Wireworld Chroma 8 2x SFP+ adapters 10GTek Router: XR700 Could anyone tell me why my Chroma's work with any ethernet port of other devices except SFP+ adapter port in my NIC (green lights blinking), but my old CAT8 cables work with it? Thanks for helpful info. Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted October 1, 2021 Administrators Share Posted October 1, 2021 I'd say that's probably something you would need to contact Wireworld or 10GTek about really! That is one expensive ethernet cable! Link to comment Share on other sites More sharing options...
Bert Posted October 1, 2021 Share Posted October 1, 2021 That chroma cable isn't even close to beeing cat 8 spec with it beeing flat and having gold connectors (gold connectors is BS since the metal on these connectors is for shielding, not conductivity) Seriously don't spend your money on that stuff. What is the length of your cable? RJ45 SFP+ transcievers have a shorter distance limit because the transcievers cannot supply the same power as a 10Gbe RJ45 port. Usually the transcievers state their maximum distance. If you are at short ranges then I would use a DAC cable in your case. DAC cables actually have less latency than fiber for the same length. And if you want to go wired, for 10G connections Cat 6 is enough, for short distances even 5E works altough I would be weary of that with the lower power limits of SFP+ trancievers.

John213 Posted October 1, 2021 Author Share Posted October 1, 2021 My old UGreen rj45 is 3m lenght, chroma 0.5m Link to comment Share on other sites More sharing options...
John213 Posted October 1, 2021 Author Share Posted October 1, 2021 So for lowest latency should I use DAC cable? Link to comment Share on other sites More sharing options...
Bert Posted October 1, 2021 Share Posted October 1, 2021 Yeah for that distance definitely get a DAC cable. You might want to check your NIC and XR700 compatibility list, since not everything always works, but I use Netgear AXC761. The XR700 detects that just fine, your NIC should as well.
