OK, I'm stumped. I've searched through the MOTU 8pre manual, the Knowledge Base, marketing materials, Google, and on these forums, looking for an answer.
MOTU seems to have a proprietary ADAT Optical format they call Type II. In recent products that offer high-sample-rate digital multichannel I/O by doubling the number of optical inputs and outputs, they offer a choice between "the industry Standard S/MUX (“Type I”) protocol for third-party product or MOTU’s own “Type II” protocol".
What is it? What advantage does it offer?
The only things I can imagine are:
1. Instead of putting ch. 1-4 on one pipe and 5-8 on another, they're putting all 8 channels on each, with one pipe carrying even-numbered and another carrying odd-numbered samples?
2. They're doing something different with clocking? (I recall something about the Alesis optical chips re-clocking all inputs, but my mind is a little "Error 7" on that part of the tape. )
If it's #1, that would be allow you to connect a single "Type II" optical output from a MOTU interface to a legacy non-96k converter and hear all 8 channels.
What is MOTU's "Type II" ADAT Optical format?

No idea, the recent manuals are the first I recall seeing that difference mentioned.
