Know before you buy
This cable is specifically programmed and tested for 100% compatibility with Extreme 10203 equipment. While it may function in other hardware, we recommend using it only with the specified Extreme devices to ensure reliable performance and avoid potential compatibility errors.
No, this is a passive copper cable, meaning it draws virtually no power—typically only 0.02 W—directly from the host ports. It is an energy-efficient solution that does not require any external power source.
This cable is designed for a fixed length of 2 meters (approximately 6.56 feet). Because it is a passive copper DAC, it is intended for short-range, high-density connections within a single rack or between adjacent server cabinets.
Yes, that is the primary purpose of this breakout cable. It allows you to split a single 40G QSFP+ port into four independent 10G SFP+ channels, making it ideal for high-density server environments.
This cable is backed by a 10-year limited warranty. This covers manufacturing defects and ensures the cable meets its performance specifications throughout its operational lifespan.
