Netwerkkabel Cisco QSFP-100G-CU3M QSFP QSFP 3m

Cisco QSFP to QSFP copper direct-attach 100GBASE-CR4 cables provide a cost-effective physical link for very short-distance 100 Gigabit Ethernet connections between QSFP-100G ports on Cisco switches, suitable for use within a rack or between adjacent racks.

Advantages

These QSFP to QSFP copper direct-attach cables deliver low-latency, power-efficient connectivity without the need for separate transceivers. They reduce total hardware cost for short links and simplify cabling between Cisco QSFP-100G ports while maintaining the 100GBASE-CR4 electrical interface standard.

Key specifications

• Interface: QSFP to QSFP
• Standard: 100GBASE-CR4
• Media type: Copper direct-attach cable (DAC)
• Application: Very short links within a rack and between adjacent racks
• Compatibility: QSFP-100G ports on Cisco switches

How to use

Insert each QSFP connector into the QSFP-100G port on the corresponding Cisco switches until the connector latches. Ensure both switches support 100GBASE-CR4 over DAC and verify link status in the switch management interface. Route the cable to avoid sharp bends and strain; keep the length appropriate for within-rack or adjacent-rack connections.

Recommendations

Confirm compatibility with your specific Cisco switch model and firmware version before deployment, and choose the shortest practical cable length to ensure optimal signal integrity and airflow in the rack.
