Frequently Asked Questions
What is a QSFP56 DAC cable used for?
A QSFP56 DAC cable is used for high-speed data center interconnections between servers, switches, and storage systems. The 200GBE QSFP56 cable supports ultra-fast 200 Gbit/s connections over short distances, making it perfect for top-of-rack and end-of-row deployments.
What are the advantages of copper DAC over optical cables?
Copper direct attach cables offer lower latency, reduced power consumption, and significantly lower cost compared to optical transceivers. The HPE 200GBE DAC is ideal for short-reach connections within data centers where cost efficiency and performance matter.
Is the HPE R8M57AR compatible with other vendors?
While designed for HPE infrastructure, QSFP56 DAC cables often work with standards-compliant networking equipment. Verify compatibility with your specific switch or server model before deployment.
What is the maximum recommended distance for this 200GBE cable?
The 2-meter length is optimized for short-reach data center applications. For longer distances, optical QSFP56 modules are recommended to maintain signal integrity and performance.
