400G QSFP-DD to 8x 50G SFP56 PCC (Passive
Copper Cable), also known as Direct Attach Copper (DAC) cable or Twinax
cable, provides robust connections between 400G Ethernet (2x 200GE) and 50G
Ethernet systems. Each cable consists of eight lanes each operating at data
rates of up to 50Gb/s (PAM4). The passive copper cables require no additional
power to ensure quality connectivity. The cables are compliant with QSFP-DD MSA
and SFP56 MSA standard specifications and provide connectivity between system
units with a QSFP-DD (QSFP56-DD) port on one side and up to eight different
SFP56 ports on the other.
