Frequently Asked Questions
What is a 100GBase-CU QSFP28 direct attach cable used for?
A 100GBase-CU QSFP28 direct attach cable connects high-speed networking equipment in data centers, providing 100 gigabit connectivity between switches, servers, and storage systems. It's ideal for rack-to-rack connections and Infiniband EDR cluster interconnects where low latency and high throughput are critical.
Is this QSFP28 cable compatible with Cisco equipment?
Yes, the AddOn QSFP28-100GB-PDAC3MLZ-C is Cisco-compatible and works with Cisco Nexus switches, UCS servers, and other multi-vendor QSFP28-equipped infrastructure. It meets industry standards for seamless integration into existing deployments.
What does LSZH jacket mean and why does it matter?
LSZH (Low Smoke Zero Halogen) is a cable jacket material that produces minimal smoke and no toxic halogen gases if exposed to fire. This makes it safer for enclosed data center environments and meets fire safety codes in many jurisdictions, particularly in Europe and regulated facilities.
Can I use this passive copper cable beyond 3 meters?
No, passive copper direct attach cables are distance-limited by signal integrity. The 3-meter maximum reach is the specification for this cable. For longer distances, active optical cables (AOCs) or powered transceivers are required.
