> The reason I ask is that I often push the limits of current gigabit ethernet distances and have found that actual limits are much shorter than theoretical limits meaning some network cards have a hard time negotiating at full speed and often fall back to 100mb unless forced
Does it have problems on single unbroken cable like that or it just has few patch-panels along the way ? IIRC the standard was for 100m unbroken cable, not the usual of device -> cable -> patchpanel -> cable ->patchpanel -> cable -> patchpanel -> cable -> device
- throw0101b 3y agoThe TIA structured cabling standard assumes patch(5m)+run(90m)+patch(5m): * https://www.youtube.com/watch?v=kNa_IdfivKs&t=11m48s https://www.youtube.com/watch?v=kNa_IdfivKs&t=11m48s * https://www.truecable.com/blogs/cable-academy/maximum-ethernet-cable-length https://www.truecable.com/blogs/cable-academy/maximum-ethern... With the ISO standard the length is strictly informative, and the length of a cable/run doesn't matter as long as the signal characteristics are good: * https://www.youtube.com/watch?v=kNa_IdfivKs&t=12m32s https://www.youtube.com/watch?v=kNa_IdfivKs&t=12m32s
- LinuxBender 3y agoJust over 120m 400 ft preformed firewall to firewall between two houses. Sometimes it works better if I turn off EEE. I've tried a few models of firewalls/nics all mini-pc's, all Intel. I think I'm just slightly over the rated length. Using buriable cat-7 in a conduit meant for fiber. Had the conduit run by the same people that installed the fiber.
- jwiz 3y agoI'm sure you considered it, but fiber might fit this application better? Also, AIUI, having the electrical isolation between the 2 buildings is nice.
- LinuxBender 3y agoFiber would be better. I've indeed contemplated it and may end up going that route.
