Frequently Asked Questions
What is the primary advantage of a Direct-Attach Copper (DAC) cable over fiber optics for 40GbE?
DAC cables like the QSFP40GPC05M are significantly more cost-effective for short distances (typically up to 7 meters) and consume less power than optical transceivers and fiber cables. They offer a simpler, lower-latency solution for in-rack or adjacent-rack connectivity.
Is this StarTech.com QSFP+ cable compatible with non-StarTech.com networking equipment?
Yes, this cable is MSA (Multi-Source Agreement) compliant, meaning it adheres to industry standards for QSFP+ transceivers and cables. This ensures broad compatibility with QSFP+ ports on switches, routers, and NICs from various manufacturers.
What is the maximum distance this 40Gbps QSFP+ DAC cable can reliably support?
The QSFP40GPC05M is designed for a length of 0.5 meters. While DAC cables can generally support up to 7 meters for 40GbE, this specific model is optimized for very short, in-rack connections to ensure maximum signal integrity and performance.
Does this cable require any special configuration or drivers for operation?
No, as a passive direct-attach cable, the QSFP40GPC05M is plug-and-play. It does not require any specific drivers or software configuration; simply connect it to compatible QSFP+ ports on your networking devices.
