Features of the 200G QSFP56 to 200G QSFP56 DAC Direct Attach Cable

A DAC is two transceivers attached together by a copper cable, creating a one part assembly. Like, AOC, Direct Attach Cable can not be separated. Direct Attach Cables are the perfect cost effective solution to connect devices seperated by small distances. DAC are mostly used to connect switches, servers and storage inside the same rack or an adjacent rack of a data center for example.
