Multiple Choice

The 200G QSFP56 FR4 is a 200-Gigabit Ethernet single-mode transceiver for up to 2 km links. It uses 4×50G PAM4 lanes over CWDM4 wavelengths around 1310 nm on a duplex LC interface, with a 200GAUI-4 electrical host—ideal for spine/leaf fabrics, data-center interconnect within campus, and metro access uplinks.
