High-Performance 40G Connectivity for Top-of-Rack and Rack-to-Rack Links
The Genuine Cisco QSFP-H40G-CU3M is a 3-meter 40GBASE-CR4 Direct Attach Copper (DAC) cable designed for short-distance, high-speed connections between Cisco QSFP+ ports. Ideal for rack-to-rack links, Top-of-Rack (ToR) to end-of-row switches, or connecting switches and routers in dense data center environments.
As a passive copper DAC, it delivers near-zero power consumption, ultra-low latency, and maximum signal integrity—making it the most cost-effective solution for 40G Ethernet in modern data centers.
Why Choose the QSFP-H40G-CU3M?
- Rack-to-Rack Flexibility: 3-meter length is perfect for interconnecting switches across adjacent racks or long ToR runs.
- Low Latency, Low Power: Passive copper means no transceivers, no optical conversions, and near-zero power draw.
- Cost-Effective 40G: Eliminates the need for expensive optical transceivers and patch cables.
- Factory-Sealed Cisco Quality: Guaranteed compatibility, hot-swappable, and built for mission-critical uptime.
Technical Features:
- Data Rate: Up to 40 Gbps (40GBASE-CR4)
- Cable Type: Passive Twinax Direct Attach Copper (DAC)
- Length: 3 meters (9.8 feet)
- Connectors: QSFP+ to QSFP+
- Wire Gauge: 30 AWG
- Power Consumption: Near-zero (Passive)
- Hot Swappable: Yes
- Operating Temp: 0°C to 70°C
- Compliance: MSA Compliant, IEEE 802.3ba, RoHS
