CBL-SAST-0973-1T Supermicro 25cm Cable

High-Density PCIe NVMe Internal Interconnect Cable for OCuLink x4 Backplane Links with the CBL-SAST-0973-1T

The CBL-SAST-0973-1T is a Supermicro internal OCuLink x4 host-to-host cable engineered for PCIe NVMe storage fabrics inside rack servers, GPU nodes, and dense all-flash platforms where deterministic signal integrity is critical. By providing a direct SFF-8611 to SFF-8611 x4-lane path, the CBL-SAST-0973-1T supports low-latency connectivity between an NVMe backplane and a storage controller, HBA, or PCIe switch without the insertion loss and handling risks of improvised routing.

In modern CPU and accelerator systems where PCIe Gen4/Gen5 expansion and NVMe drive density compete for limited internal space, the CBL-SAST-0973-1T enables clean chassis-to-backplane interconnect planning. Its 25 cm straight form factor is sized to maintain controlled routing in 1U/2U storage servers, helping reduce connector strain and minimizing airflow disruption around hot-swap bays and PCIe riser zones. This makes the CBL-SAST-0973-1T a practical choice for U.2/U.3 NVMe backplane wiring and scalable storage domains aligned to high IOPS and mixed read/write workloads.

Why Choose the CBL-SAST-0973-1T?

The CBL-SAST-0973-1T delivers an enterprise-relevant density-to-performance advantage by enabling x4-lane OCuLink backplane links in space-constrained platforms while preserving maintainability and predictable service loops. For operators standardizing cabling across storage nodes, the CBL-SAST-0973-1T supports repeatable builds, reduces integration variability, and scales cleanly as PCIe topologies expand.

Supermicro designs internal interconnect components to match server chassis tolerances and data centre operational requirements, emphasizing mechanical fit, consistent assembly quality, and reliable connectivity for continuous-duty environments.

Key Applications:

• NVMe backplane to controller interconnect
• U.2/U.3 internal PCIe storage cabling
