QSFP-DD Connectors and Cable Assemblies

QSFP-DD for High-Performance Computing

QSFP-DD (quad small form-factor pluggable double density) doubles the density of QSFP interconnects with an eight-lane electrical interface capable of 28 Gbps NRZ or 56 Gbps PAM-4 to achieve 200 or 400 Gbps aggregate per port. The QSFP-DD portfolio’s backwards compatibility allows existing QSFP modules to be plugged into QSFP-DD ports. Our QSFP-DD cages feature a proprietary heat sink design, making them the only solution to work in 15-18W applications at a low cost – providing superior thermal and signal integrity performance.

Product Features

QSFP-DD Cable Assemblies
  • QSFP-DD cable assemblies are similar to QSFP28 4 channel (8 pair), but use double the channels to 8 (16 pair) by using a 2nd row of contact/pad locations on the front of the PCB 
  • Maximum cable reaches to meet IEEE 802.3cd SDD21 requirement of -17.28dB at 13.28 GHz
  • 16 pair 28AWG cable maximum fit (2.5m), plans for as small as 32AWG
  •         QSFP-DD to QSFP-DD 
  •         QSFP-DD to 2x and 4x QSFP28/56 
  •         QSFP-DD to 8x SFP28/56
