Yes i always use conduit so that if needed i can just pull another cable through. I have got rolls and rolls of gel filled outdoor cat5 which I use for connecting the radios on people's roofs but when i had a few problems at another site with animals chewing it, i started putting it all in black pvc pipe and havent had a problem since.
GoodSync. Easily back up and sync your files with GoodSync. Simple and secure file backup and synchronisation software will ensure that your files are never lost (affiliate link).
So how do you run a 'vdsl bridge' over 480m? Do you have converters that send it down one pair? surely it isnt just a straight ethernet connection over that distance
You set one as Central Office and the other as Customer Premesis mode, and run a cat5 cable up to 2km between them. Cat5 is used as telephone cable these days.
very cool piece of kit. Will keep that in mind for when we do smaller jobs. would of been perfect for a sawmill we just did. We would use 2-pair grease filled as thats what we have on hand. This forum is great!!
2. While we can try to reason with humans and publicize our underground cable, there is nothing we can do about our next biggest pain in the rear, and that’s squirrels! Of all the animals in the whole world, almost all of our animal damage comes from this furry little nut eater. Squirrel chews account for a whopping 17% of our damages so far this year! But let me add that it is down from 28% just last year and it continues to decrease since we added cable guards to our plant. Honestly, I don’t understand what the big attraction is or why they feel compelled to gnaw through cables. Our guys in the field have given this some thought and jokingly suspect the cable manufacturers of using peanut oil in the sheathing. If you have any new ideas on how we can combat these wayward rodents, I’d love to hear from you. We are always looking for ways to improve.
It comes from the grid, to a step down isolator so its completley isolated, then it goes via a regulating charger to a 12v battery bank, then back through an inverter up to 110v, through one of those RCD thingys for outdoor appliances and then through a 0.5amp fuse.
Took an electrician friend up there and his comments were "your cabling looks safer than the grid cabling" which is all pretty old.
But yeah, i have to be safe because there are sheep and stock that could chew on the cable - even though there is an electric fence line on most of the fences, so they are trained to stay away already, but i like to be safe anyway.
chevrolux: Oh and just another note, why woud you have to get some one to fix a broken cable? If it's laid properly there shouldnt be an issue ;)
Rabbits i guess. Not really sure. Also because of the ground conditions, like 30m of rocks sticking out, the area cant be trenched so the cable will be attached to a fence.
okay so i have been sufficently scared away from fibre.
Good old trusty VDSL it is.
Perhaps the 30m rocky stretch could run through some armoured flexi like this or the whole lot if you want it really protected. If you do go with multimode fibre, get it preterminated with enough slack to manage in an enclosure on each tower.
