Cabo breakout CBO QSFP para 4x SFP+ MC2609130-001, 1 m, 40 Gbit/s

The CBO QSFP to 4x SFP+ Breakout Cable MC2609130-001 is a passive direct-attach copper cable that converts a single 40 Gbit/s QSFP port into four independent 10 Gbit/s SFP+ links over a 1 metre length. Designed for high-density switching and server interconnects, this breakout cable provides short-reach, low-latency connectivity for data center and enterprise network environments where consolidated QSFP ports need to be distributed to multiple SFP+ interfaces.

Advantages

This 1 m passive breakout cable supports an aggregate bandwidth of 40 Gbit/s while splitting the link into four 10 Gbit/s channels, enabling efficient port utilization and simplified cabling. Being a direct-attach copper assembly, it offers low power usage compared with active optical solutions and provides reliable, low-latency performance for short-reach connections. The compact design reduces rack space and simplifies deployment when converting QSFP ports to multiple SFP+ endpoints.

Suitable for

• High-density top-of-rack switches requiring QSFP-to-SFP+ breakout
• Server uplinks where a single 40 Gbit/s port must feed multiple 10 Gbit/s interfaces
• Data center aggregation and spine-leaf architectures with short-reach links
• Environments prioritizing low latency and power-efficient cabling

Key specifications

• Connector type: QSFP to 4 × SFP+ breakout
• Length: 1 metre
• Aggregate data rate: 40 Gbit/s (4 × 10 Gbit/s lanes)
• Transmission medium: passive direct-attach copper
• Use case: short-reach, within-rack or adjacent-rack connections
• Form factor compatibility: QSFP port to SFP+ ports

How to use

Insert the QSFP plug into the 40 Gbit/s QSFP port on the switch or network device and connect the four SFP+ ends to the corresponding 10 Gbit/s SFP+ ports on target devices or servers. Ensure ports are powered down or in a hot-plug-supported state according to your hardware vendor guidance before connecting. After physical installation, verify link status and port configuration in the device management interface; configure each 10 Gbit/s port as required for VLANs, MTU, and traffic policies.

Recommendations

Use this passive breakout cable for short-distance within-rack or adjacent-rack connections; avoid runs beyond typical short-reach copper limits. Confirm compatibility with your switch and server vendor for passive DAC assemblies and check port settings after installation to ensure proper lane mapping and link negotiation.
