I have been researching this heavily over the past few days and this is what I am "thinking" about doing for fiber and power up tower.
1. Run a MPT/MPO fiber trunk cable up tower (12 fibers) https://www.fs.com/products/68017.html (indoor version but available immediately in USA shipping)(could use this temporarily) https://www.fs.com/products/70220.html (custom length rugged outdoor version but takes 30 days to get here from Asia) 2. Run each end of the MPT Trunk into a "MPT-12 to 6x LC Duplex Cassette" (tower top this will be in an enclosure) https://www.fs.com/products/57017.html 3. Run custom length FTTA LC connector Patch cables from the Tower Top enclosure to each radio SFP https://www.fs.com/c/ftta-patch-cables-3856 4. For Power run individual power wires or a combination of multi-conductor wire "cord style." The cord below is 12 guage but has 4 conductors. If wired properly you could individually power 3 radios and use a common ground wire and still be able to power cycle the 3 radios from the ground. If I need 6 radios I will run a second cord. My towers are only 150' tall so I think 12 guage should be more than big enough for me even with Medusa AP's. https://www.ebay.com/itm/250-ft-12-4-SJOOW-SJO-SJ-SJ00W-Black-Rubber-Cord-Outdoor-Flexible-Wire-Cable/143388108175?hash=item216298e58f:g:KSQAAOSwA0JclR2G I would run the power cords and fiber trunks into a common tower top enclosure and wire out from there. I really like this Trunk cable idea with the fiber because If done right there will be absolutely no splicing of fiber at all. If the Trunk cable goes bad just run a new one up and plug it into the Cassettes and everything should keep working. You could standardize on a couple different lengths of the MPT fiber trunk 150' or 250' and just stock those and coil up excess cable outside or something. I was un-aware that Medusa AP's needed 8 gauge wire at 300' but i guess it could make sense.
