CBL-MCIO-1225M5Y Supermicro 25cm Cable

High-Density Internal PCIe Breakout Cable enabling MCIO lane fan-out with the CBL-MCIO-1225M5Y

The CBL-MCIO-1225M5Y is an internal MCIO PCIe breakout cable designed for MCIO-based Supermicro server platforms that require controlled PCIe lane distribution between a host connector and downstream risers or NVMe backplanes. By converting 1 x MCIO x8 straight connection into 2 x MCIO x4 straight connections, CBL-MCIO-1225M5Y supports clean lane allocation for PCIe expansion topologies where slot, riser, or backplane layout dictates split connectivity.

In modern CPU platforms where PCIe lane budgets and routing constraints drive system design, the CBL-MCIO-1225M5Y helps maintain signal-path integrity and serviceability within dense chassis. The 25cm length is optimized for internal cable management between motherboard MCIO headers and adjacent interconnect points, enabling predictable routing in high-density compute, GPU nodes, and NVMe-accelerated storage configurations. When used as a server PCIe/NVMe backplane cabling element, CBL-MCIO-1225M5Y supports modular storage and expansion architectures without forcing board rework or nonstandard harnessing.

Why Choose the CBL-MCIO-1225M5Y?

The CBL-MCIO-1225M5Y provides an architecturally correct method to fan out an 8-lane MCIO path into dual 4-lane endpoints, improving density-to-performance planning for risers and backplanes while preserving enterprise deployment consistency. As a datacenter service spare, CBL-MCIO-1225M5Y aligns with scalable maintenance workflows by enabling standardized replacement and minimizing downtime during platform refreshes or field repairs.

Supermicro designs interconnect components with an emphasis on platform compatibility, predictable mechanical fit, and reliable operation under continuous datacenter duty cycles. This engineering approach supports repeatable builds and adherence to modern server cabling standards across compute, storage, and accelerator-oriented architectures.

Key Applications:

• PCIe riser connectivity in dense servers
• NVMe backplane interconnect and lane breakout
• GPU and accelerator node internal expansion
• Datacenter service spare for MCIO harnessing
