## Long description

The BlueOptics R9D20A-BL is a 3 m SFP+ Direct Attach Cable (DAC) designed for short-distance high-speed connections in racks and between adjacent racks.

As a passive twinax DAC it consumes very little power (around 0.1 W), offers low latency and a low failure rate due to its simple design. It is tested for compatibility with the respective vendor platforms and offers an economical alternative to branded original cables while maintaining the same interface functionality.
Suitable for
Short-distance 10G connections within racks and between adjacent racks
Switch-to-switch, switch-to-server or switch-to-storage links
