Perfectly true, but I'd just like to add that reflections are not purely a problem of optical cable. You will also get reflections in a coax cable, at every change in characteristic impedance. For example, that budget RCA connector on the spdif output of the SB3 will cause a reflection. The heavy expensive RCA connectors on some digital cables are not designed for 75 ohms, and they too will cause reflections. I'm not aware of ANY XLR connectors that maintain a 110 ohm impedance, so, you guessed it, reflections on your AES/EBU interface as well. I can't say which interface is best or worst, I don't have nearly enough measured data, but there seems to be a lot of anti toslink comments on the web, without much supporting data. Yes it's an inexpensive interface, but frankly, so are a lot of the coax interfaces I've seen.... As always, YMMV! Cheers!
