SMUGDESK SFF8654 4i 38Pin to SFF8643 36Pin SAS Cable 1.5 FT

Slim SAS 38-pin to Mini SAS HD 36-pin bridge

This cable connects an SFF-8654 4i Slim SAS host port to an SFF-8643 Mini SAS HD target port. It is designed for enterprise storage administrators and server integrators building high-density internal links. The 1.5 ft length suits tight 2U or 4U chassis where excess slack would impede airflow. It is not for users needing longer runs or external bulkhead connections.

PCIe 4.0 and SAS 3.0 sustained throughput

The assembly meets PCIe 4.0 and SAS 3.0 electrical specifications, keeping signal integrity stable under continuous heavy I/O from RAID arrays or NVMe SSD clusters. High-quality copper conductors reduce insertion loss and crosstalk during extended workloads. No active equalisation or retimer circuitry is present, so link budget depends on the host and target controllers.

Passive copper thermals and power profile

As a passive copper interconnect, the cable draws no power and adds no active cooling requirement. Heat contribution is negligible inside the server airflow path. The slim 38-pin and 36-pin connectors fit dense backplanes without blocking adjacent slots. No fan, radiator or external power adapter is involved.
