Cable length between 2 wISP switches ?

[jjonsson]

Any idea if I can run 1 Gbps between 2 wISP switches when cable length will be 125 meters (410 feets). Will it work ?
I will use TOUGHcable Carrier.....

If I have to pull fiber, it will be to expensive as I need a fiber capable switch in both ends + SFP moduls....

[jjonsson]

My plan is to use 2 x WS-6-MINI. I will connect the cable at each end in a 50 V PoE (AF PoE), that powers the switches....

Hooking 2 switches together that are on different AC power services and thus (2) different Earth Grounds which means 2 different ground potentials is not such a good idea. You will constantly burn out Ethernet ports if not switches.

I would use fiber.

Now if you were going to power the WS-6-MINI over the Ethernet and did not need much additional POE watts at the other end you could do that?

However if your powering a radio with the far side WS-6-MINI even if it is powered from POE in on port 1 then the radio from that seconds WS-6-MINI gets grounded to another Earth Ground source then you still have 2 different ground potentials which is also bad again.

It is important that everything connected via copper share the same Earth ground potential.

with Chris. If this is a horizontal run with unbonded disparate grounds, it is a recipe for trouble.

It is not clear however what you mean by "I will connect the cable at each end in a 50 V PoE". I assume that both locations have their own AC mains and that you don't intend to push PoE power over that long run. If that is the case, I would up the game to use switches with SFP ports and run fiber between them. That, or use the new Ubiquiti PoE powered media converters.

Agreed. We had this discussion just the other day didn't we Chris? ;)

It's within same building, so exact same earth grounding. I just need to place equipment in both ends of the house and total cable run is around 125 meters...

Unfortunately https://www.ubnt.com/accessories/fiber-poe-accessory/ is not available in Europe yet.

Preconnectorized fibercable + mediaconverters / SFP modules + switches is to expensive. I can't use SFP+WS-6-MINI, instead I need WS-10-250-AC in both ends + SFP modules = To expensive :-(

Twisted Pair CAT 5e standard says 90 meters. This cable need to be 125 meters. Will it work ? Have anyone tried similar ?

I will power the WS-6-MINI switch with an AirFiber 50V PoE brick. And I will have 1 x WS-6-MINI in both ends, so that will be 2 x switches and 2 x PoE bricks...


So just a plain EtherNet connection with 125 meters cable run between switches ? Will it work ?

I personally have ran CAT5e over 125 and it worked.

I personally have ran CAT5e over 125 and it worked.

Me too but would not do gig.

Did it do 1 Gbps ?

[sirhc]

Sometimes yes, sometimes no.

Sorry, many variables such as cable quality and noise along cable runs such as electric wires and florescent lights.
