Black Box QSFP+ Network Cable - Cisco-Compatible 40 Gbps Direct Attach Cable (Part Number: QSFP-H40G-CU2M-BB)

The Black Box QSFP+ Network Cable (Part Number: QSFP-H40G-CU2M-BB) is engineered to deliver high-performance, error-free data transmission for demanding network environments. Designed for seamless compatibility with Cisco switches, routers, and servers, this 40 Gbps direct attach cable ensures reliable interconnectivity for data, storage, and high-performance computing applications. Fully compliant with industry standards like MSA and SFF-8436, the cable also supports connections among non-Cisco networking equipment, providing flexibility and scalability in diverse network setups. Its serialized, tested construction guarantees consistent performance, making it an ideal choice for high-speed Ethernet and fiber channel environments.

The ultra-thin, lightweight design of this cable facilitates high-density rack installations, reducing strain on ports and improving airflow for better equipment cooling. Utilizing optical technology, the cable supports higher bandwidth over longer distances—far exceeding copper solutions’ typical 5-meter limit—thus maintaining signal integrity and minimizing bit error rates. Its all-in-one, hot-swappable design simplifies deployment by eliminating the need for separate transceivers and cables, while also reducing latency through fewer connection points, which is critical for applications requiring real-time data processing.

Constructed with fiber optic technology, the cable offers superior resistance to electromagnetic interference and radio frequency interference, ensuring clean, stable signals in sensitive, high-density environments. Additionally, fiber optic transmission inherently provides a higher level of physical security, making it difficult to tap into the data stream. The cable’s robust construction supports operating temperatures from 0 to 70 degrees Celsius and is made with CL2-rated PVC jacket material, ensuring compliance with safety standards. Its low power consumption further enhances its appeal as an energy-efficient component for high-speed network infrastructure.

The Black Box QSFP+ Network Cable is perfect for point-to-point, intra-rack connections of 40-Gbps equipment. It complies with RoHS standards, is environmentally friendly, and is manufactured in China to strict quality specifications. Backed by a lifetime limited warranty, this cable offers a reliable and secure solution for data centers, enterprise networks, and HPC clusters, ensuring long-term performance and value.
