Why is the small form factor so important?

POET can offer a 20mm-wide chip option that can fit four 100G LR4 optical engines or up to 16 lasers into a 10-km or 2-km fiber solution. If you want that miniature form factor and the benefits in performance and cost savings, you have to use POET’s solution. There’s no other way to fit so many components inside the QSFP-DD packaging.

Now I know this is from the FAQ blog from Poet.  But do "all roads lead to POET", "there won't be two POET's".  Quotes from????  lol Empire club.
