Some questions:

1. Would you need two of them at a $430 cost for this?

2. If so would the person be much better with alternative solutions like fixed wireless or Ethernet-VDSL2 conversion that would deliver much better performance at this price point?

Yeah approx $400 for a pair. Mainly chip shortage messiness, I think I can get the cost down to less than $200 a pair in April 2023.

Regarding VSDL, never used it myself; I guess it would come down to space/power considerations. I haven't seen VDSL used much in the industrial automation, single pair ethernet seems to be the preferred choice.

Long range networking is a very overcrowded market. You need something that is either really good or really cheap.

The economics in buying this is whether re-running the 1-km of copper with whatever media you want will cost $430 or less.

I think just rolling a telecom truck will cost you this.

Yeah fair. I'm aiming at new space constrained applications with this.

These emerging Ethernet standards are cost effective upgrades for large industrial objects like warehouses and monstrous vehicles.

You may have an unused phone line or just some reserved pins in a connector, and the cable runs a quarter mile to the other end of “this”. The existing solution is working, albeit inconvenient, and it will be nice to be able to just add Ethernet telemetry or control to it. That’s where these shine.

Further more, why would someone choose this over $59.69 a pair fiber ether net media converter, up to 20KM, 1000Mbps from TP-LINK? There are most likely cheaper options from other vendors.

Don't forget the SFP's you need as well.

There are actually different models have laser trans-receivers built in with same or might even cheaper price. So unless there are very special requirements, I don't really see a reason to go for those.
