Never expected this to work

Gigabit ethernet through 108 meters of sheilded cat 5e. was expecting at most tbase 100.

Re: Never expected this to work

With good network cards on both ends (or good switch), it's possible.

Years ago, I installed a FTP cat5e cable between two buildings and I know for sure it was more than 105 meters, I think it was in the range of 107-110 meters. It was working fine with no packet loss and transfers around 600-800 mbps 24/7 (students in university campus sharing movies and music between them)

got any packetloss?

I think 100M is 'safe' not strict

Try making 10base2 (thin ethernet coax) work over 1000'. Lots of packet loss but it did work and that was on a repeated (not switched) network with about 300 nodes. Things are only impossible until they are tried.

Re: Never expected this to work

I was certifying the structured cabling at a collage a few years back and from one of the art studio pc labs that every point was over 200m with UTP... It did 'work' but the switch wasn't happy about it. Nor were they when we pointed out it at least needed re-routing to a nearer cab, taking a more sensible route, and hoping it came into spec, or possibly installing a small cab in the lab.

Re: Never expected this to work

Ok from what I understand cat 5e is good for gigabit to 100 meters

Re: Never expected this to work

The maximum length allowed by standards is 105 meters. Wikipedia says 100 meters but I know I remember it as 105 meters.

There is some note in the standard ( ) saying something about 5 meters not included for patch cords and internal cabling but I'm not curious and patient enough to read the whole damn thing.

Cat5e is rated for 1Gbps at up to 100 meters including patch cables on both ends.
So if you don't have patch cables it will improve the signal.
And you say that you used shielded cables, which further improves things.

Re: Never expected this to work

Doesn't sound as impresive now only 3 meters over length.

For some reason I had in my mind 30m for cat 5
aNd needed cat 6 for gigabit at 30m +

I think I was confusing cat 5e specs with cat 5.

Not looked it up.

Also this is a poe cable.

spec's dont mean much when they keep improving the line-driver in the chipsets.
