Overview

Siemon Interconnect Solutions SFP28 Passive Copper Cable assemblies exceed 25G Ethernet (25GBASE-CR) specifications. They are designed for high-density applications, offering a cost-effective, low-power option for high-speed data center interconnects. This next generation product shares the same mating interface with SFP+ (SFF-8431) form factors, making it backward compatible with existing SFP+ ports. These direct attach cable assemblies are available in standard lengths up to 5 meters (16.4 ft.) for 25G Ethernet applications.

  • Positive retention pull-release latch system
  • SFP28 connector
  • Ultra low crosstalk for enhanced performance
  • PCB Termination - Laser stripped conductors
  • PCB Termination - Overmold provides additional strain relief to minimize pistoning
  • PCB Termination - Automatic welding for unmatched consistency
  • PCB Termination - Welding results in less dielectric shrink-back than soldering
