Frequently Asked Questions
What is a 100GBase-CU direct attach cable used for?
A 100GBase-CU direct attach cable connects high-speed network ports in data centers and enterprise environments. It's commonly used for switch-to-switch, switch-to-server, and server-to-server links where 100GbE bandwidth is required over short to mid-range distances (up to 5 meters with passive copper).
What does TAA compliant mean for networking cables?
TAA compliance (Trade Agreements Act) certifies that the product meets U.S. government procurement standards. This is essential for federal agencies, contractors, and regulated organizations that must source equipment from approved manufacturers and countries of origin.
Why choose passive twinax over active cables?
Passive twinax cables like this QSFP28 direct attach cable eliminate active components, reducing power consumption, heat generation, and cost. They're ideal for shorter distances (5 meters) and offer lower latency compared to active optical or electrical alternatives, making them perfect for high-performance computing clusters.
Is this cable compatible with my network equipment?
Yes. This AddOn cable is MSA compliant and factory-serialized with unique programming to ensure compatibility with standard QSFP28 ports on switches, routers, and servers. The cable is tested before shipment to guarantee plug-and-play operation in your 100GbE infrastructure.
