Mellanox mcp1600 c0xxeyyz direct attach copper dac cables are high speed cost effective alternatives to fiber optics in 100gb s ethernet applications. Show more show less. Fs offers 40g qsfp direct attach cable assemblies in passive dac and active dac from 0 5m to 10m which are most cost effective choice to connect two 40g port of different network switches. One major application is connecting network hardware through their sfp interfaces.

This type of connection is able to transmit at 10 gigabits second full duplex speed over 5 meter distances. A direct attach copper cable or a dac cable is a twinax copper cable that connects directly the ports or line cards within active equipment such as switches routers servers or data storage devices in a data network. The hpe direct attach cables provide connections to meet the exponential data growth in data centers and cloud based services. Mellanox qsfp28 passive copper cable contains four high speed copper pairs each operating at data rates of up to 25gbe.
