The difference between AOC and DAC

The difference between AOC and DAC

Generally speaking, there are several differences between AOC active optical cables and DAC high-speed cables:

① Different power consumption: The power consumption of AOC active optical cables is higher than that of DAC;

② Different transmission distances: theoretically, the farthest transmission distance of AOC can reach 300M, while the farthest transmission distance of DAC is 7M;

③ The transmission medium is different: AOC’s transmission medium is optical fiber, while DAC’s transmission medium is copper cable;

④ The transmission signals are different: AOC transmits optical signals, while DAC transmits electrical signals;

⑤ Price difference: The price of optical fiber is higher than that of copper, and in addition, AOC contains lasers at both ends but DAC does not, so the price of AOC is much higher than that of DAC;

⑥ Different volume and weight: Under the same length, the volume and weight of AOC are much smaller than those of DAC, making it easier for wiring and transportation.

In general, DAC high-speed cables can be used for interconnection distances within 5m, and AOC high-speed cables can be used for interconnection distances between 5m and 100m.
