Opto is an emulation of physical analog compression implementation, and RMS (root mean square) is mathematical function.
Opto doesn’t have a singular mathematical function like RMS because different implementations will yield different transfer functions and detector ballistics.
So what you might ask is “how does this specific opto compressor affect topology compared to a simple RMS circuit”
If it uses a lightbulb it’s slower (but can still be peak because the light will respond to peak or RMS if there’s an RMS circuit to drive the light source) if it uses an LED it’s faster.
The answer is “ask the developer/manufacturer” or chuck in a bunch of test signals to reverse engineer the topology.
Edit: so yes, a slow lightbulb opto might superficially act RMS-ish, but it depends on how quick the light source is and what kind of photosensor it uses.
If you used a fast sensor and an optical fibre it would be as fast as peak.
