Frequently Asked Questions
What is a QSFP56 direct-attach cable used for?
A QSFP56 DAC cable connects high-speed network equipment like switches and servers within data centers. It provides 200Gb connectivity over short distances (up to 2.5m) with minimal latency, making it essential for modern enterprise networking infrastructure.
Is a refurbished HPE DAC cable reliable?
Yes. HPE refurbished (Reman) cables undergo rigorous testing and certification to meet original specifications. This 200Gb QSFP56 cable delivers the same performance as new units at a fraction of the cost, backed by enterprise-grade quality standards.
How does a passive DAC cable differ from active options?
Passive direct-attach cables require no power and generate no heat, making them ideal for dense deployments. This HPE model operates passively, reducing operational costs while maintaining full 200Gb throughput over 2.5 meters.
What equipment is compatible with the HPE R5Z79AR?
This QSFP56 cable works with any HPE or third-party networking equipment featuring QSFP56 ports, including switches, servers, and storage arrays supporting 200Gb connectivity standards.
