25G SFP28 AOC: The Market and Trends

In general, there are three ways of 25G access of server, namely DAC (Direct Attach Cable), optical transceiver and AOC(Active Optical Cable). DAC can reach no more than 5m, so it is difficult to meet the requirements of cross-rack wiring distance. The optical transceiver can reach up to 100m or more using multi-mode fiber, but the cost is high. AOC is an Active Optical Cable. AOC can reach up to 30m at a reasonable cost. Therefore, AOC cable is a good choice for cross-rack server access, which is more suitable for China's current data center rack power and network architecture. Here’s some information about the 25G AOC that you may be wondering about. 25G AOC provides a cost-effective solution for those same data center applications that require longer distance interconnect using active optical Ethernet technology. There are some advantages to 25G AOC . The Advantages of 25G AOC 25G is the next trend from 10G to reduce the cost per Gbit/sec 25G provides 2.5 times the b...
