Black Box QSFP-H40G-CU1M-BB 40Gbps Direct Attach Cable
Overview
The Black Box QSFP-H40G-CU1M-BB is a 1-meter Direct Attach Copper (DAC) cable designed for high-density, high-speed network environments. It provides a cost-effective, low-power solution for short-reach 40-Gigabit Ethernet (40GbE) connections between switches, servers, and storage devices within a rack or adjacent racks. This cable is ideal for data centers and enterprise networks requiring robust, high-bandwidth interconnectivity without the expense of active optical modules.
Compatibility
This QSFP+ cable is compatible with any network equipment featuring standard QSFP+ ports, including switches, routers, and network interface cards (NICs) from major manufacturers. It is designed to meet the specifications for 40Gbps Ethernet and Infiniband connections, ensuring interoperability with a wide range of enterprise-grade networking hardware.
Installation Notes
The QSFP-H40G-CU1M-BB requires no configuration. Simply plug the QSFP+ connectors into the corresponding ports on your network devices. Ensure the connectors are fully seated to establish a stable connection. The cable is designed for passive operation, meaning it does not require external power. The black color aids in identification within dense cabling infrastructure.
