Form factors
The QSFP-DD, QSFP-56 and OSFP might be popular with PAM4 technology, while CFP8 might be a good candidate for the Coherent application*.
To support these new technologies, a bunch of new form factors are coming on the market*. Some will be popular while some will remain for a niche market.
