100G QSFP28 AOC Active Optical Cable
100G QSFP28 AOC Active Optical Cable is widely deployed in data centre.
With data rate up to 100Gb/s QSFP28 AOC is the perfect choice for super computing, large data storage and cloud service.
Compared to DAC, AOC active optical cable supports longer distance and lower maintenance cost.
AOC Background
1.With the expansion of data center computer room area, the unit computer room area and functional areas have increased, increasing the transmission distance of backbone subsystem cables. When the cable is limited by a length of 100 meters, the usage of optical fibers will increase.
2. AOC active optical cable has higher bandwidth and longer transmission distance, making it a product suitable for future cabling. It can adapt to the increasing network development trend of data transmission speed, bandwidth, storage capacity, etc. in future data centers. With the significant increase in optical port shipments and the continuous maturity and improvement of technology, its price will significantly decrease. The cost advantage of copper cable as a transmission medium will gradually weaken, and in terms of energy consumption, optical fiber has a unique advantage.
3.In the future, with the development of data centers towards high density, the industrialization concept of cloud computing data centers based on cabinets means that copper cable wiring in horizontal links will be greatly reduced, and data center systems will mainly be composed of AOC cables.
