100G QSFP28 Direct Attach Copper Cable Assemblies are high speed, cost effective alternatives to fiber optics in Ethernet, Fiber channel and Infiniband technology applications. The cable assemblies enable hardware OEMs and data center operators to achieve high port density at low cost, while helping to reduce power consumption. The QSFP28 Copper cable form factor uses 8 differential pairs that provide 4 data transmission channels, can meet industry MSA for signal integrity performance.
Based on users’ real situation, QSFP28 100G DAC has following types as below:
QSFP28 100G QSFP28 100G Cable assembly, length 1~5m, provides 4 data channels with 25G channel rate.
QSFP28 100G to 2 x QSFP28 50G breakout cable assembly, length 1~5m; The 2XQSFP28 side only use 2 lanes in each port with 25G channel rate.
QSFP28 100G to 4 x SFP+ 25G breakout cable assembly, length 1~5m. Support users to link QSFP28 port to SFP Ports.
