There’s a lot of things here that are feasible, because many modules are in the
same form factor, eg XFP that is EDFA etc.
The specs (SFF-8024) have a variety of types and encodings with GBIC 2.4.2 and
table 4.2
The SFF-8024 is being revved to v4.9.2 right now, so there’s always
enhancements.
The SFP can be used to do SDI or other types of output that are non-IP.
It is nice to seeing things move to CMIS if you’ve dealt with all the
lack-of-clarity in the hardware and software specifications for what bits are
set or required to be set, which is why some optics haven’t always worked
because the EEPROM had TX_Disable set or similar.
