- 1km of fiber optic cable - https://www.amazon.com/Jeirdus-Launch-Singlemode-Measuring-O... - 1Gb modem - https://www.amazon.com/TP-Link-Ethernet-Converter-Multi-Mode... The price for two modems and the cable is just under $120
It seems that single mode fiber is king for long distance cable runs now, nevermind that it can push gigabits. What kind of cable would this be and is it actually much cheaper? My impression is that most cost of cabling now is the labor to run it as opposed to the medium, but I'm a neophyte for sure.
I wired my house with 62/125 fiber 22 years ago as a 1 km spool was only $250. I’m too lazy to look it up, but I suspect multimode fiber is cheaper than copper, and termination kits are cheap now. I’m running 10G on single mode 100 ft jumpers to a few computers in the house and that’s cheap too. SFP are $35 but the NIC are more.

You need something more like this:
- Terminated single-mode fiber: https://www.fs.com/products/74355.html?attribute=255&id=3029...
- 2x SFP transceivers: https://www.fs.com/products/75335.html
- 2x media converters (or NICs): https://www.fs.com/products/96396.html
The price is over $200.

> It seems that single mode fiber is king for long distance cable runs now, nevermind that it can push gigabits. Bandwidth isn't the only consideration: you can deliver power over copper: * https://en.wikipedia.org/wiki/Power_over_Ethernet#PoDL * https://www.ti.com.cn/cn/lit/an/snvaa25/snvaa25.pdf
They make plenty of fiber+power in single cable, because the fiber is unaffected by the power.
Running 1km of slow, expensive, single-pair cable to run low-data rate + power, vs fiber+power cable saves you essentially one connector. For very high cost - in money and loss of bandwidth.
Plus 10base-t1l is not common, so the price of equipment is high as well.
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?
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.

Basically just any CAT5e like twisted pair has worked for me up to 1km. 26AWG unshielded twisted pair basically, 100Ohm diff impedance. Cost of cabling is pennies IMO. Labor cost, who knows. Optical can be quite expensive though these boards aren't exactly cheap (yet).
The world is not the same as it was 15 years ago :)

If it's purely down to cost then I don't these modules would compete

1KM of fiber cable for $60 seems crazy cheap when you contrast it with 3D printer filement. More so as I'd of thought the former be more expensive to manufacture.
