Fair enough. I was estimating complexity really. I don't recall an expected data rate being called out although "optical" would imply something like 20 Mpbs.

Cheap SFPs will happily run at 10Gbit/s.

you could even skip all the PLL stuff, just set a FF on the falling edge after >1.5period high, clear FF on rising edge after >~1.5period low
Biphase always has a transition mid-bit. So a transition detector and a 0.75t non-retriggerable one-shot soon syncs up.
I knew that decades ago and sort of forgot.
Only if you have non-constant data. You already rejected several suggestions based on the fact that they required non-constant data to sync up.
Sometimes I wonder if you know what you want.
Last time I looked I can buy 8-bit bytes by the Giga. Never encountered a company that sold 6-bit bytes.
