DAC cable and AOC cable are widely applied in storage area network, data center, and high-performance computing connectivity, etc.
But DAC and AOC are arguing:
Direct Attach Cables (DAC): I'm more popular in Data Centers.
(1) Cost Savings: When implemented in a large data center, DACs can significantly reduce costs over same length AOCs.
(2) Lower power consumption: DACs cooling requirements are not strict due to their thermal design which lowers power consumption and decreases data center operating expenses.
(3) Wider operating temperature: DACs don’t produce heat thus making it a more versatile product that can be used in wider temperature ranges.
(4) Reliability and faster transmission: The mean time between failures (MTBF) is about 500 million hours making them reliable with fast transmission. This MTBF makes DACs essential for data centers.
Active Optical Cables (AOC): No, Most enterprice like to choose me, plug and play, Easy to use.
(1) Greater Bandwidth: Without any equipment upgrades, AOCs have a throughput of up to 40Gbps with QSFP+.
(2) Bend Radius: The cables of AOCs are thin and have a significant bend radius making AOCs the optimal solution if data centers don’t have enough space for cabling.
(3) Air-flow and cooling: Due to the AOC cable being thin in design, the switches will have more room for air flow and easy for cooling system.
So the purchasing manager, which one you will choose?
AOC vs. DAC: the correct choice can be made when you are clear about the advantages and disadvantages of each. and need clear about your application and requirement.
HTF’s DACs and AOCs can help turn up your networks faster and keep them up and running.
