In this article, ETU-LINK will introduce to you, what is the difference between active optical cable(AOC) and direct attach cable(DAC)? First, the AOC is composed of integrated optoelectronic devices. The signal transmission process is that the A terminal module converts the electrical signal into an optical signal, the optical signal is transmitted to the B terminal module by an optical fiber pat...
