Yole Développement is proud to publish the reverse costing report on the latest generation 40Gbps photonic circuit from Luxtera.
The  1064101003 Quad Small Form-factor Pluggable Plus connector from Molex integrates this photonic circuit from Luxtera which manages 40Gbps data rate on a single silicon die assembled directly in the connector case.

This new component is two times smaller than the first generation in 130nm. This technology is  targeted  for very high data rate on short and medium distances. It integrates its laser source in a tiny original MEMS package.

This report provides complete teardown of the die with:
