SFF-8643 4i plug / SFF-8643 4X plug*2

Description

SFF-8643 4i plug Mini SAS HD 4i to Dual 4i Internal Cable Assembly – High-Speed Fanout for SAS 24G Storage and Server Systems

The Mini SAS HD 4i to Dual 4i internal cable assembly, featuring SFF-8643 compliant connectors, is a high-performance fanout solution designed to split a single Mini SAS HD 4i interface into two independent 4-lane SAS channels. Engineered for SAS 6G/12G/24G signaling, this cable enables efficient bifurcation of high-speed data lanes in enterprise storage, server, and high-performance computing environments.
