In the era of big data, high-density, high-bandwidth applications are becoming more and more common, and passive optical cables or copper wire systems emerge. In order to ensure transmission stability and flexible applications, users urgently need a new type of product as the main transmission medium for high-performance computing and data centers.
Compared with traditional cables, optical transmission cables have the advantages of high transmission speed, long transmission distance, low energy consumption, and easy use.
What is an AOC cable?
AOC is short for Active Optical Cable. Active optical cable is a high-speed cable that integrates photoelectric conversion technology. It refers to a communication cable that requires the use of external energy to convert electrical signals into optical signals or convert optical signals into electrical signals during the communication process. The optical transceivers at both ends of the optical cable provide photoelectric conversion and optical transmission functions.
AOC cable structure and technology
AOC consists of optical fiber, photoelectric converter (Transceiver) and connector. Optical fibers are responsible for long-distance transmission of signals, photoelectric converters convert electrical signals into optical signals, and connectors ensure compatibility with other devices.
