CBL-NTWK-0575 Supermicro 300cm Cable

High-Density Breakout DAC Interconnect for Top-of-Rack Fanout with the CBL-NTWK-0575

The CBL-NTWK-0575 is a passive copper direct-attach breakout cable designed to convert a single QSFP switch or NIC port into 4x SFP+ downlinks, enabling clean 10GbE fanout within a rack. In top-of-rack deployments, the CBL-NTWK-0575 supports deterministic, low-latency in-rack connectivity without the operational overhead of transceivers, making it well suited for leaf-to-server or QSFP-to-SFP+ aggregation patterns.

Architecturally, the CBL-NTWK-0575 aligns with high-throughput server platforms where PCIe-based network adapters and storage traffic compete for predictable east-west bandwidth. By keeping the interconnect in copper and within short-reach constraints, the CBL-NTWK-0575 helps preserve signal integrity and simplifies change control for clustered GPU and CPU nodes that depend on consistent link behavior. The 3m length is optimized for structured rack layouts, supporting orderly cable management between top-of-rack switches and densely populated 1U/2U systems.

Why Choose the CBL-NTWK-0575?

The CBL-NTWK-0575 delivers a pragmatic density-to-connectivity advantage: one QSFP port can service 4x SFP+ endpoints while maintaining an enterprise-friendly cabling model for scale-out racks. Using a passive breakout design, the CBL-NTWK-0575 reduces component count and potential points of failure compared to optical paths, supporting repeatable deployments across lab, staging, and production clusters.

Supermicro designs interconnect components to match data centre operational realities, focusing on compatibility with common rack server and switching ecosystems, consistent build quality, and predictable behavior under continuous load. This approach supports standards-aligned integration and efficient lifecycle management in enterprise environments.

Key Applications:

• Top-of-rack QSFP to SFP+ fanout
• 10GbE server/NIC breakout connectivity
• In-rack cluster and lab cabling
• Switch port consolidation for scale-out racks
