Direct Attach Copper

Sfp direct attach copper dac is a popular choice for 10g ethernet reaches up to 10 m due to low latency and low cost.

Direct attach copper.

The following figure shows leading types of passive and active cable for data center. 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. 10g sfp twinax cable direct attach copper dac passive cable 0 5 meter for cisco sfp h10gb cu0 5m ubiquiti d link supermicro netgear mikrotik zte 14 49 99 customers who bought this item also bought.

One major application is connecting network hardware through their sfp interfaces. Sfp direct attach as implied in the name uses sfp msa and by using the inexpensive copper twinaxial cable with sfp connectors on both sides provides 10 gigabit ethernet connectivity between devices with sfp interfaces. 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.

Short direct attach cables use a passive twin ax cable assembly while longer ones sometimes called active optical cable aoc use short wavelength optics. Also known as direct attach da direct attach copper dac 10gsfp cu 10gbase cr 10gbase cx1 sfp or 10gbe cu sfp cables. Mellanox qsfp28 passive copper cable contains four high speed copper pairs each operating at data rates of up to 25gbe. As two kinds of commonly used transceiver assemblies both direct attach copper cable and aoc cable have their advantages and disadvantages.

Hpe direct attach copper cables. Sfp direct attach is known as the successor technology to 10gbase cx4. Direct attach copper cables can either be passive or active while aoc cables are always active. The hpe direct attach cables provide connections to meet the exponential data growth in data centers and cloud based services.
