Frequently Asked Questions
What is a 100GBase-CU QSFP28 direct attach cable used for?
A 100GBase-CU QSFP28 direct attach cable connects QSFP28-equipped switches, servers, and storage systems over short distances in data centers. It provides 100 Gigabit connectivity without requiring separate transceivers, making it cost-effective for rack-level interconnects and high-performance computing environments.
Why choose passive copper over active cables?
Passive copper direct attach cables eliminate power consumption, reduce heat generation, and lower total cost of ownership compared to active cables. They're ideal for short-reach applications under 3 meters where signal integrity remains excellent without amplification.
Is the LSZH jacket important for my data center?
Yes. The LSZH (Low-Smoke Zero-Halogen) jacket is critical for fire safety compliance in enclosed spaces. It produces minimal smoke and toxic gases if exposed to fire, protecting equipment and personnel while meeting building codes and industry standards for data center installations.
Will this cable work with my Cisco infrastructure?
Absolutely. The AddOn QSFP28-100GB-PDAC1MLZ-C-AO is Cisco compatible and meets or exceeds OEM specifications, ensuring seamless integration with Cisco switches, routers, and networking equipment supporting QSFP28 ports.
