Description
IB 12x to 3× 4x External Cable Assembly – High-Speed Fanout for InfiniBand and SAS Interconnects
The IB 12x to Triple 4x external cable assembly, featuring one SFF-8470 12X plug and three SFF-8470 4X plugs, is a high-performance fanout solution designed for external data transmission in InfiniBand, Serial Attached SCSI (SAS), and other high-bandwidth applications. Engineered for 100-ohm differential impedance and available in 32AWG to 24AWG wire sizes, this cable enables efficient bifurcation of a 12-lane interface into three independent 4-lane channels—ideal for scalable enterprise and HPC deployments.
