200G AOC cables deliver high density and speed, supporting next-generation Ethernet applications. DOUBLE DENSITY, COST EFFICIENT, HIGH PERFORMANCE Amphenol QSFP DD to QSFP DD 200G Active Optical Cable assemblies increase the number of lanes from 4 to 8 and double the port density as compared to 100G QSFP28 AOC. Designed for high-performance computing and networking environments, they enable fast data transfers with reduced electromagnetic interference. When you see “200G AOC,” it is a version of Active Optical Cable that supports. AOC stands for Active Optical Cable, which is an active type of cable also known as an active fiber optic cable. AOCs are equipped with both an electro-optical conversion chip and an opto-electronic conversion chip, and are used to transmit high-speed signals through optical fibers.
