What about 100G QSFP28 AOC Active Optical Cable?
Knowledge Base + 2024.01.12

The increasing demand for data transmission by users is pulling the whole optical communication market. Optical devices are essential in optical communication, and AOC active optical cable is a necessity for data transmission. 

Active Optical Cable AOC is a product born to address the needs of high-density, high-bandwidth applications, with high transmission rates, long transmission distance, low energy consumption, ease of use and many other advantages that can help communication equipment to enjoy the great advantages of optical transmission, is the ideal transmission cable for data centers, consumer electronics and other fields.

As the name suggests, 100G AOC active fiber optic cable refers to the communication process requires the use of external energy, will be converted to optical signals, or optical signals into electrical signals communication cable, optical transceivers at both ends of the cable to provide optoelectronic conversion and optical transmission function, and the transmission rate reaches 100Gb/s. And the AOC active fiber optic cable is composed of two optical transceivers and a fiber optic cable patch cable, and both ends of the fiber optic transceiver device and different lengths of fiber optic transceivers and different lengths of fiber optic transceivers and different lengths of fiber optic transceiver devices and different lengths of fiber optic transceiver devices. The AOC active optical cable consists of two optical transceivers and a fiber optic patch cord with OM3 or OM4 multimode fibers of different lengths at both ends.
