Frequently Asked Questions
What is a passive DAC cable and how does it differ from active options?
A passive DAC (Direct Attach Cable) uses copper conductors to connect network ports without active electronics or power consumption. Unlike active DACs or optical transceivers, passive cables reduce latency, eliminate heat generation, and lower total cost of ownership—making them ideal for short-reach 100G connections in data centers.
Is this QSFP28 DAC cable compatible with non-Juniper equipment?
While optimized for Juniper Networks devices, this 100GBASE-CR4 passive DAC follows industry-standard specifications. Compatibility depends on your specific switch or router model. Verify your equipment supports QSFP28-to-SFP28 breakout configurations before deployment.
What is the maximum recommended distance for this 0.5m passive DAC?
The 0.5-meter length is ideal for rack-to-rack or switch-to-storage connections within data center environments. Passive DACs typically support distances up to 5-7 meters depending on cable quality and environmental conditions, but shorter runs like this ensure optimal signal integrity and performance.
Can I use this cable for 100G QSFP28 DAC applications outside Juniper networks?
Yes, the 100GBASE-CR4 standard is vendor-neutral. This passive DAC works with any equipment featuring QSFP28 and SFP28 ports that support 100G breakout mode. Always consult your hardware documentation to confirm compatibility before purchase.
