Frequently Asked Questions

What is the primary advantage of an Active Optical Cable (AOC) over Direct Attach Copper (DAC) for this breakout configuration?

An AOC like the QSFP4X10GAO3 offers longer reach (3 meters in this case) and is lighter and thinner than DAC cables, making cable management easier. AOCs are also less susceptible to electromagnetic interference, ensuring more reliable data transmission in noisy environments.

Is this cable compatible with non-Cisco networking equipment?

While specifically tested for Cisco compatibility, this cable complies with MSA (Multi-Source Agreement) industry standards. This means it is generally compatible with other brands of networking equipment that adhere to these same QSFP+ and SFP+ standards.

Can this cable be used to connect a 10GbE switch to a 40GbE switch?

Yes, this breakout cable is designed for exactly that purpose. It allows a single 40GbE QSFP+ port on a core switch to connect to four separate 10GbE SFP+ ports on access switches, servers, or other network devices, facilitating efficient network scaling.

What are the environmental operating conditions for this cable?

The StarTech.com QSFP4X10GAO3 is designed to operate reliably in temperatures ranging from 0 to 70 °C (32 to 158 °F). This wide operating range ensures stable performance in typical data center and server room environments.
