DAC cable is often used in short-distance cabling schemes in data centers. Compared with other AOC active optical cable and optical module transmission schemes, it has high performance cost ratio , but the short transmission distance is its limitation. If the equipment spacing exceeds the length of direct attach cable, it is necessary to choose AOC active optical cable and optical module scheme. T...
