Hi folks,We're looking at running an Ethernet to link two buildings which are quite a distance apart (around 220 metres, possibly around 230 metres maybe).Now I understand that the official limit on length of CAT5 is 100 metres, however I'm wondering if anyone has pushed the length any further?The thought I had was to run CAT5 to a waterproof box just under half way, in there have a 10/100 switch powered by POE, and run the rest of the cable to the other location (this might be about 130 metres). I'm not sure if putting another switch on the cable run (again POE powered) would be an option due to it being outside (it could be tampered with, or eaten by a horse).Other than Ethernet (and wireless which probably won't work due to line of sight issues), what other options might we have?I've even considered 10Base2 coax cabling (is it still available?) or Thick Ethernet? (only ever seen that once at school back in the 90s, again is that still available? Can it go faster than 10Mbit?) Or... okay, maybe I'm verging on crazy now... Token ring?Fibre was considered but I'm not sure if it would be too fragile to run.I think ideally it would be nice to have 100mbit, but we could probably get away with 10 or 20Mbit/sec.Rob
I'd go for fibre inside trunking. Fibre "cable" isn't just the skinny glass "wire", it's coated and sheathed and should be pretty bendy.
I'm no fibre expert but I know my local school did just this to get between buildings. They have CAT5->fibre gismos at each end - don't you need specialisr kit to cut the fibre cable?
