Frequently Asked Questions

What is the primary advantage of an active optical cable (AOC) over a passive copper cable?

An AOC like this 15-meter StarTech.com cable can transmit data over much longer distances than passive copper cables without signal degradation. This is crucial for connecting equipment across larger data center footprints or between distant racks, where copper cables would experience significant performance loss.

Is this cable compatible with non-Cisco networking equipment?

Yes, while designed and tested for Cisco compatibility, this cable also complies with MSA (Multi-Source Agreement) industry standards. This ensures broad interoperability with other major networking brands that adhere to these standards for QSFP+ and SFP+ transceivers.

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

No, this is a breakout cable designed to convert one 40GbE QSFP+ port into four distinct 10GbE SFP+ links. It is not intended for a single 10GbE connection, but rather for distributing 40GbE bandwidth across multiple 10GbE devices.

What are the environmental compliance certifications for this cable?

This StarTech.com cable is certified for REACH, RoHS, CE, and FCC compliance. These certifications ensure the product meets strict environmental, safety, and electromagnetic compatibility standards for enterprise deployment.
