SFPH 10 GBACU 10 M vs SFP 10 GAOC 10 MThis is once agian about the difference between 10 G AOC and DAC cables . We understand that the DAC passive copper cable is only suitable for really shortreach applications . While AOC cable possesses the better transmission performance but with higher cost in both material and daily use , and it needs more power as well . As for the DAC active copper cable , it can can support 40 G transmission up to 15 meters with low power consumption , and satisfy the regular interconnection requirement for distance and cooling in most data center . What ' s more , it is less expensive . $ 40 difference between them is really not much money , what really matters is the performance . I used the 10 G DAC cables 10 gsfpdac 1364 in my network and I thnk it is sufficient for me .
