Slimline SAS SFF-8654 8i Splitter Cable
This cable connects a single 74-pin SFF-8654 8i port to two 38-pin SFF-8654 4i ports for internal SAS storage. It serves builders wiring backplanes or controllers that use the Slimline connector standard.
Three-connector assembly enables dual 4i fan-out
The three connectors split one 8i lane into two independent 4i links without active electronics. This lets a single controller port address two separate backplanes or drive cages while maintaining the 64Gbps PCIE 4.0 data rate.
Straightforward internal routing
The 100cm reach suits typical server chassis but cannot be shortened or extended. Installers must verify that the 74-pin and 38-pin keying matches their specific hardware, as mismatched pinouts are the common cause of link failures.

Questions about this item
Will the SFF-8654 8i 74pin connector or the dual SFF-8654 4i 38pin ends need periodic replacement under normal use?
The cable is a passive assembly with no moving parts; connectors are rated for repeated mating cycles and do not require scheduled replacement.
What limits sustained 64Gbps throughput on this 100cm SAS cable first — signal integrity or connector thermal limits?
Signal integrity over the 100cm length at PCIe 4.0 speeds is the primary limit; the passive design has no active components to generate heat.
Does the cable generate noticeable heat or draw extra power when running at 64Gbps all day?
As a passive copper assembly it draws no auxiliary power and produces negligible heat even during continuous 64Gbps operation.
