Our small form-factor pluggable (SFP) product portfolio is expanding with new small form-factor pluggable double density (SFP-DD) products for input/output (I/O) interconnects. The “double density” cages and surface mount connectors can offer two-channel data transmission, instead of the traditional one-channel in an SFP architecture, which helps data center systems to provide doubled port density with faster data transfer rates.

2-lane interconnect with higher density and better signal integrity than SFP28/56

  • Concept leverages QSFP-DD surface mount technology (SMT) design
  • Compared to SFP28/SFP56 solutions, SFP-DD cages and connectors provide double the density and double the speed, reaching up to 112 Gbps via two channels
  • Designed for both 28G NRZ and 56G PAM-4 protocols, with a roadmap for 112G PAM-4


  • Can provide an easy upgrade path for existing SFP solutions

Space savings

  • Free up more space of PCB and faceplate as compared to QSFP28/QSFP56 solution
  • One port with upgraded functions: extend to two channels 28G NRZ and 56G PAM-4
  • Can address challenges generated by underpopulated lanes as a natural complement to QSFP-DD interfaces

Industry leading thermal management

  • Offers superior thermal management with TE’s innovative thermal bridge technology
  • According to MSA specification, SFP-DD interconnect solution can offer 3.5W thermal management (current SFP interconnect solution: 1.5W) with SFP-DD cages, having a longer structure to leave more space for heat dissipation

Offer design flexibility with customized solutions and stacked configurations

  • Support standard and customized light pipes and heatsinks
  • Available with solder tail and press fit cage
  • Stacked version design is in development
