Know before you buy
This cable is designed to bridge 40G QSFP+ ports on switches or routers to four individual 10G SFP+ ports on servers or other network devices. It is an efficient way to increase port density and manage high-speed connections within a data center rack.
Yes, this cable is specifically engineered for Mellanox hardware compliance. Each unit is pre-programmed and tested to ensure seamless integration with your existing Mellanox infrastructure.
No, this is a pre-terminated Direct Attach Copper (DAC) cable. It is ready for immediate use right out of the box and does not require separate transceivers or complex software configuration.
This copper DAC cable is highly efficient, with a typical power consumption of only 0.02 W. It consumes significantly less power than active optical cables, helping to reduce the overall energy footprint of your network hardware.
This specific model is designed for short-reach connections within a rack or between adjacent racks, with a total length of 0.5 meters. Because it uses copper conductors, it is best suited for high-speed, low-latency links over these shorter distances.
