The Cisco QSFP-100G-CU3M= is a 3-meter, passive 100GBASE-CR4 Direct Attach Copper (DAC) twinaxial cable with QSFP28 connectors on both ends. Designed for short-reach, high-speed connectivity within data centers, it provides a cost-effective and low-power solution to link 100 Gigabit Ethernet ports on Cisco switches, routers, and servers. It supports 4 lanes of 25Gbps data transmission, fully compliant with IEEE 802.3bm and QSFP28 MSA standards.
100Gbps Total Bandwidth: 4 independent 25.78Gbps full-duplex channels.
Passive, Low Power: No active electronics; consumes ≤0.5W from the host port.
Hot-Pluggable: QSFP28 form-factor for easy installation without powering down the host.
High Flexibility: Minimum bend radius of ~38mm for dense cable management.
Shielded Construction: 26 AWG twinaxial copper with foil shielding for low crosstalk.
Standards Compliant: IEEE 802.3bm, SFF-8665 (QSFP28), SFF-8636 (CMIS), RoHS 6.
Cisco Validated: Fully tested and certified for Cisco Nexus 9000/3000, Catalyst 9500/9600, and ASR 9900 series.
Cost-Effective: Ideal for intra-rack and adjacent-rack connections vs. optical transceivers.
Industrial Reliability: BER < 10⁻¹⁵; operating temp: 0°C to 70°C.
