Frequently Asked Questions
What is a QSFP28 DAC cable used for?
A QSFP28 DAC cable is used for high-speed data center connections between switches, servers, and network appliances. The passive design provides 100Gbps connectivity without the cost and power consumption of active optical transceivers, making it ideal for short-distance interconnects in enterprise and cloud environments.
Is this cable compatible with Ubiquiti equipment?
Yes, this Axiom 100GBASE-CR4 QSFP28 cable is specifically designed to be Ubiquiti compatible, ensuring seamless integration with Ubiquiti UniFi switches and other 100GBASE-CR4 compliant networking devices.
What is the maximum distance for a 100GBASE-CR4 DAC cable?
Passive DAC cables like this 0.5m model are optimized for short-reach connections, typically up to 5 meters. The 0.5 meter length is ideal for densely packed data center environments where devices are in close proximity.
How does a passive DAC cable differ from an active cable?
Passive DAC cables use direct copper connections without electronics, consuming no power and generating minimal heat. Active cables include signal conditioning electronics. For short distances like 0.5m, passive DAC technology provides superior cost-efficiency and reliability.
