SFP-H10GB-CU3M Datasheet
(SFP+ Direct Attach Passive Copper Cable)


  • Support for multi-gigabit data rates up to 10.5Gbps
  • Data rates backward compatible to 1Gbps
  • Hot-pluggable SFP 20PIN footprint
  • I/O Connector designed for high speed differential signal applications
  • Improved Pluggable Form Factor(IPF) compliant for enhanced EMI/EMC performance
  • Compatible to SFP+ MSA
  • Temperature Range: 0~ 70 °C
  • RoHS Compliant


  • High capacity I/O in Storage Area Networks, Network Attached Storage, and Storage Servers
  • Switched fabric I/O such as ultra-high bandwidth switches and routers
  • Data center cabling infrastructure
  • High density connections between networking equipment


The SFP+ passive cable assemblies are high performance, cost effective I/O solutions for 10G Ethernet and 10G Fiber Channel applications. SFP+ copper modules allow hardware manufactures to achieve high port density, configurability and utilization at a very low cast and reduced power budget. The high speed cable assemblies meet and exceed Gigabit Ethernet and Fiber Channel industry standard requirements for performance and reliability.
