QSFP56-DD electrical interfaces will employ eight /four lanes that operate up 50/100 Gbps PAM4 modulation, providing solutions up 400 Gbps aggregate

QSFP28-DD electrical interfaces will employ eight lanes that operate up to 25 Gbps NRZ modulation , providing solutions up to 200 Gbps aggregate.

Eoptolink is developing OSFP(Octal Small Form Factor Pluggable) a new pluggable form factor with eight high speed electrical lanes that will initially support 400 Gbps (4*100G and 8x50G)
