StarTech QSFPH40GCU05 0.5m 40Gbps Direct Attach Cable
Overview
The StarTech QSFPH40GCU05 is a 0.5-meter (1.6 ft) passive copper direct attach cable designed for high-speed 40Gbps networking. It provides a cost-effective, low-power solution for short-reach interconnections between QSFP+ ports on switches, servers, or network interface cards. This cable is ideal for data center top-of-rack deployments or connecting network equipment within a single rack, minimizing signal degradation and power draw compared to active optical cables.
Compatibility
This cable is 100% Cisco QSFP-H40G-CU0-5M compatible, ensuring seamless integration with Cisco networking equipment. It utilizes standard QSFP+ connectors on both ends, making it broadly compatible with any network device featuring QSFP+ ports that require a 40Gbps passive copper connection.
Installation Notes
The cable operates within a standard 0°C to 70°C (32°F to 158°F) temperature range. Each end draws less than 0.1W, simplifying power planning for your network infrastructure. The cable jacket is constructed from PVC for flexibility and durability in typical data center environments.
