Hello!
What about Single Pair Ethernet (SPE) on mikrotik devices? Any plans, products in the future?
Very small connectors, long reach. Cheap 10 or 100 Mbit/s solutions, Power over (the same) Dataline (PoDL).
And (mostly) all you’d have to do is to exchange the PHY and leave the (Software) rest as it is.

I thinks it’s use is very internal to car and industrial. The chipsets and PHY:s probably costs according to.
Well, Single Pair Ethernet efforts might have originated firstly with an automotive emphasis but if you look at the roadmap and already available silicon it is clearly not only automotive and industrial but also domestic, building and other networking - all under the same roof - Ethernet. So basically it is about exchanging the PHY which is available at similar prices as standard 10/100/1000 PHY, depending on the speed grades you want. Think about re-using legacy 2-wire cabling in your house.
Do you mean Cat3 telephony wires ?
I’m actually running an ethernet connection over Cat-3 telephone cable. I found I needed to lock it to 10Mb/s because if I allowed it to go faster, the retries were so bad that the overall throughput was lower. For the application, a connection at 10 Kilobit would be more than enough.
It is unlikely to be of good enough quality. 100BASE-T1 requires a pair with specifications similar to Cat5e and 1000BASE-T1 similar to Cat6A, both have a reach of 15m being primarily targeted for automotive use. 10BASE-T1L has a reach of 1km but only 10Mbps and requires decent twisted pair cable, it being targeted at reusing the cabling of existing instrumentation in industrial settings as that is often the most expensive item to upgrade. There are some standards still in development supporting longer reach 100Mbps, but only with substantially better cable (16 or 18 AWG conductors rather than 22 or 24 AWG).
