Can the OFC be replaced with wireless for the ISP primary backhaul from POP till the boradband distribution control center. Pls chk for my comments in RED color in the pic. attached.
If you’ve got control over both ends, sure. But in wireless there is not a one size fits all. Your current and near future needs to to taken into account, as well as available resources, mounting options, path and path obstructions ect. You’ll want to familiarize yourself with grounding theories also… People new to the wireless world tend to skip out on good grounding and regret it later.
You don't really provide enough information to allow us to make a definitive answer, and as Chris mentions, there are a number of factors at play here... putting all that aside and assuming that a number of critical questions are in your favor or positive, then YES... you could replace that fiber with a wireless link.
