QSFP28 to 4 SFP28 25/100G Passive Copper Cable AssembliesEnlarge this image

Overview

Siemon QSFP28 to 4 SFP28 Passive Copper Cable assemblies exceed 100G Ethernet (100GBASE-CR4) 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 QSFP+ (SFF-8436) and SFP+ (SFF-8431) form factors, making it backward compatible with existing QSFP+ and SFP+ equipment ports. These direct attach cable assemblies are available in standard lengths up to 5 meters (16.4 ft.) for support of up to 100G (4x25G) Ethernet applications.

  • Ultra low crosstalk for enhanced performance
  • High-density QSFP28 connector
  • Positive retention pullrelease latch system
  • 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
