400G QSFP56-DD PCC (Passive Copper
Cable), also known as Direct Attach Copper (DAC) cable or Twinax
cable, provides robust connections for 400G Ethernet (2x 200GE) and InfiniBand
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 standard
specifications and provide connectivity between devices using QSFP-DD
(QSFP56-DD) ports.
