Optocoupler datasheets seem like kind of a mess, I try not to use them

Have you used anything like these?
https://www.digchip.com/datasheets/parts/datasheet/477/ISO485P.phpWhat other methods are available which can cope with communication between equipment on different power line phases?
Apart from the obvious transformer isolation used in computer networking?
And RF isolation such as Wireless networking and Bluetooth.
