CPO is a new optoelectronic integration technology, also known as co-packaged optics. It assembles the network switching chip and the optical module together in the same slot to realize the co-packaging of the chip and the module. This technology improves the transmission speed of electrical signals between the chip and the engine by shortening the distance between the switching chip and the optical engine. This not only reduces size and efficiency, but also reduces power consumption.
