ACPL (Analog CMOS Photonic Link) optocouplers are a specific series of optically coupled isolation devices developed by Broadcom. These optocouplers utilise a combination of photonic and CMOS technology to provide high-performance analogue signal isolation.

Applications of ACPL optocouplers include high-speed data communication, precision instrumentation, medical equipment, industrial automation, and power electronics, among others. Their combination of high-speed performance, low power consumption, and reliable isolation makes them suitable for a wide range of demanding applications where accuracy, efficiency, and safety are critical.
