Frequently Asked Questions
What is a 100GBase-CU QSFP28 direct attach cable?
A 100GBase-CU QSFP28 direct attach cable is a passive copper interconnect that delivers 100 Gbps connectivity between network equipment using QSFP28 ports. The AddOn ET7402-DAC-1M connects directly without requiring separate transceivers or active components, making it an economical choice for short-distance links.
Is the AddOn ET7402-DAC-1M compatible with my Edge-corE equipment?
Yes, the AddOn ET7402-DAC-1M is specifically designed as an Edge-corE ET7402 compatible cable. It works with any QSFP28-equipped network device that supports 100GBase-CU passive copper connections, ensuring broad compatibility across your infrastructure.
What are the advantages of a passive direct attach cable over active alternatives?
Passive DACs like the AddOn ET7402-DAC-1M offer lower cost, zero power consumption, minimal latency, and simplified deployment compared to active optical cables. They're ideal for rack-to-rack and short-reach connections where the 1-meter distance is sufficient.
Can I use this 1m cable for longer network runs?
The AddOn ET7402-DAC-1M is rated for reliable performance up to 1 meter. For distances beyond 1m, consider active optical cables or fiber-based solutions that support extended reach while maintaining 100G speeds.
