What is the Form Factor for 400G optics? • The first is OSFP  OSFP stands for “Octal Small Form-factor Pluggable”. The electrical interface of an OSFP connector consists of 8 electrical lanes, running at 50Gb/s each, for a total of 400Gb/s. I can only imagine how this will be confused with OSPF. • Second is QSFP-DD stands for “Quad Small Form-factor Pluggable (QSFP) – Double Density (DD)”. The electrical interface of a QSFP-DD connector also has 8 electrical lanes, running at 50Gb/s each,...
