SFF-8654 8i – SFF-8654 4i * 2 CABLE ASSEMBLY

Description

SFF-8654 8i – SFF-8654 4i * 2 Internal Cable Assembly – High-Speed Fanout for SAS 24G and PCIe Gen 4 Systems

The SFF-8654 8i to Dual SFF-8654 4i internal cable assembly is a high-performance solution designed to split a single MiniLine SAS 8i interface into two independent MiniLine SAS 4i connections. Built to the SFF-8654 specification and optimized for SAS 24G and PCIe Gen 4 signaling, this cable enables efficient bifurcation of high-speed data lanes in storage and compute platforms.
