We designed NIDs for residential use where we needed to avoid the cost of fiber or spread the cost of the fiber media converter over as many low cost connex as possible. I suspect that using a NID with nothing but a switch in it would allow you to go 1km on a single power feed. Must try it.
Just measured - a simple switch only NID draws 130mA at 12V. THats 1.56Watts. Round it up to 3 watts. Power feed gives you 48 watts. Thats 16 NIDs spaced out at 100m (ie 1.6km in ONE direction). Allow for some extra volt drop and you get 1km in one direction. Use 2 power feeds, one North and one south and you get 2km between power feeds. Wheres that drum of cable. I wonder if anyone would notice a small cable out the back of my van.....
