SFP+ Passive DAC Cable
Volex’s SFP+ passive direct attach copper cable is a cost-effective alternative to optical modules for short reach high speed interconnects. The cable assembly features 1 transmitting and 1 receiving channels and meets 10G Ethernet and 8G Fibre Channel specifications, providing high performance and bandwidth interconnect solutions for high density applications.
Volex’s SFP+ cable assembly combines twinaxial shielded cable with robust die cast housing and actuating pull latch. The overmould technique used in fabrication for these cables provides additional strain relief and minimizes conductor pistoning. This cable assembly product is designed to meet the stringent data center requirements with unparalleled performance and durability.
SFP+ Passive DAC Cable Product Highlights
