Both 100G AOC active optical cable and 100G DAC high-speed cable are used as short-distance data transmission carriers for enterprises or data centers, but there are some differences between them. 100G AOC active cable requires photoelectric conversion when transmitting signals, while 100G DAC high-speed cable does not. It is transmitted in the form of electrical signals. The following ETU-Link fo...
