FAQ
What is the purpose of a QSFP28 to 4 SFP28 breakout cable?
This breakout cable allows a single QSFP28 port, typically used for 100GbE connections, to be split into four separate SFP28 ports, each supporting 25GbE. It enables efficient use of high-speed ports in network switches and routers, facilitating connectivity to multiple devices like servers or storage arrays without requiring additional switch ports, thus optimizing network density and reducing cabling complexity.
Is this cable compatible with Fortinet equipment?
Yes, this Axiom DAC cable is specifically designed to be compatible with Fortinet networking devices. It ensures reliable performance and seamless integration with Fortinet switches, routers, and other security appliances, making it a suitable choice for deployments within Fortinet-based network infrastructures where high-speed, secure connections are prioritized.
What does 'passive' mean for this DAC cable?
A passive DAC cable does not include active electronics for signal amplification or retiming. It relies on the electrical properties of the copper twinaxial conductors to transmit data over short distances, up to 1 meter in this case. This results in lower power consumption, reduced heat generation, and a more cost-effective solution compared to active cables, while still maintaining the 100 Gbit/s data rate for reliable network performance.
