I'm not sure about separate transceivers, but the ones integrated on
NIC cards for PCs often used a little non-potted four-pin DC-DC converter
module made by TDK. At a guess, it's about 20 mm by 10 mm. I've successfully
kludged them onto boards that were designed for the potted module style.

Anyhow, I have a lifetime supply of NOS of these TDK converters, so I could
sell some cheap or trade them for other small stuff.
