Cabo breakout CBO QSFP para 4x SFP+ BlueOptics 02310MUM-BL 40 Gbit/s

CBO BlueOptics 02310MUM-BL is a QSFP to 4x SFP+ breakout cable engineered for short-reach, high-density network connections. The passive assembly splits a single QSFP interface into four independent SFP+ channels, supporting aggregated data throughput up to 40 Gbit/s. Its blue outer jacket and compact form factor are intended for use in switches, routers and servers where port consolidation and simplified cabling are required.

Advantages

The breakout cable provides four separate 10 Gbit/s lanes from a single 40 Gbit/s QSFP port without additional transceivers, reducing port conversion costs and rack-space complexity. Passive construction ensures low latency and predictable signal behavior for short distances. The compact design and keyed connectors improve installation accuracy and help maintain airflow and cable management in dense equipment racks.

Suitable for

• Consolidating multiple 10 Gbit/s links from one 40 Gbit/s QSFP port
• Short-reach connections within racks and between adjacent racks
• Interconnecting switches, routers and servers with SFP+ ports
• Upgrading infrastructure to support 40 Gbit/s aggregation without new optics

Key specifications

• Topology: QSFP to 4 × SFP+ breakout
• Aggregate data rate: up to 40 Gbit/s (4 × 10 Gbit/s lanes)
• Connector types: one QSFP plug to four SFP+ plugs
• Cable type: short-reach copper/fiber passive assembly (manufacturer designation)
• Color: blue outer jacket for visual identification
• Form factor: low-profile, high-density compatible

How to use

Connect the QSFP end of the breakout cable to a compatible QSFP port on a switch or router and plug each SFP+ connector into the target SFP+ ports on connected devices. Ensure devices are powered and configured to support split 10 Gbit/s lanes; some systems require explicit configuration or firmware support for breakout mode. Route the cable to avoid sharp bends and maintain proper airflow in the rack. For optimal performance, use the cable within the recommended short-reach distance and verify link negotiation on each SFP+ interface after installation.

Recommendations

Confirm compatibility with host hardware and firmware before deployment, and follow vendor guidance for enabling QSFP-to-SFP+ breakout modes. Use in-rack or short inter-rack connections where passive breakout assemblies are supported; replace with active or optical alternatives for longer distances or when signal conditioning is required.
