Co-packaged optics (CPO) puts the optical engine — the part that converts electrical signals into light — directly onto the switch chip's own package, instead of in a removable transceiver on the front panel. The fiber connects right at the chip. That one move is the whole idea, and it's easiest to. Different Transmission Rates: Optical ports commonly support transmission rates of 100G and above, while the maximum rate for electrical ports is typically 10G. From Jensen Huang showcasing CPO switches at GTC 2025 to a wide range of vendors demonstrating optical engines integrated inside ASIC packages at OFC 2025. Switches come in three types: those with purely Ethernet ports, those with purely optical ports, and those with a combination of both. Port types are limited to two: optical and Ethernet. Optical Transceiver Packaging Evolution: From GBIC to CPO in Data Centers Description: Explore the evolution of optical transceiver packaging from 1×9 to QSFP-DD and CPO.
