Frequently Asked Questions
What is a 40GBase-CU QSFP+ direct attach cable used for?
A 40GBase-CU QSFP+ direct attach cable connects high-speed network switches, routers, and servers within data centers and network closets. It provides 40 Gigabit connectivity over short distances (typically up to 7 meters for passive designs) without requiring separate transceiver modules, making it cost-effective for rack-to-rack and switch-to-server interconnects.
Why choose a passive twinax cable over active alternatives?
Passive twinax cables eliminate the need for power consumption and active electronics, resulting in lower operational costs, reduced heat output, and simpler deployment. For short distances like 0.5 meters, passive designs deliver full 40 Gigabit performance while maintaining reliability and ease of installation.
Is this cable compatible with my Fortinet equipment?
Yes, the AddOn FG-TRAN-QSFP+SR-PDAC50CM is specifically designed and tested for compatibility with Fortinet networking devices featuring QSFP+ transceiver slots. Each cable is factory-validated and uniquely serialized to ensure performance standards are met.
What is the maximum cable length for 40GBase-CU passive twinax?
Passive 40GBase-CU twinax cables typically support distances up to 7 meters while maintaining signal integrity. This 0.5-meter cable is ideal for short-reach applications where maximum performance and reliability are required in confined spaces.
