300m of terminated outdoor fiber where to buy

Hi guys,

Need to mount an end of a ptp bridge 300m away from a fixed solar repeater tower, aerial only needs 7w 24v,

To achieve los to a commercial tower.

instead of mucking around with poe extenders, I was thinking of doing the 300m in fiber if I can keep the cost down.

I have a netonix switch with 2 spare sfp ports and was thinking ubnt fiber poe unit at the other end with a small panel and battery
