Description
DACs are the most basic form of direct attach cabling. DACs are constructed using shielded twin-axial copper cable in varying gauges from 24 to 30AWG. The length of the cable affects the signal attenuation which requires a specific gauge for the conductors. Longer cables require larger gauges in order to reduce the signal transmission loss through the cables.
DACs are passive assemblies since they do not amplify or condition the signal in any way. Instead, signals are passed through and regenerated by the host network equipment. The length limit for passive DACs (without amplification) is 7m.
Although DACs are passive, the connectors in DACs do contain an “Electrically Erasable Programmable Read-Only Memory”, or EEPROM, that is used to store and provide information to host network equipment such as manufacturer name, serial number, part number, and date of manufacture. Technically, this EEPROM does consume a very small amount of power, around 0.15 W.
Gvdlink QSFP-100G to four SFP-25G copper direct-attach breakout cables (Figure 2) are suitable for very short links and offer a cost-effective way to connect within racks and across adjacent racks . These breakout cables connect to a 100G QSFP port of a switch on one end and to four 25G SFP ports of a switch / server on the other end. Gvdlink currently offers passive cables in lengths of x=1 , 2 , 3 and 5 meters.
