The terms 100G-2, 100G-4, 50G-2, 200G-4 and 400G-8 are abbreviations for different types of Ethernet interfaces that use different numbers of lanes and different modulation schemes to achieve different data rates. The general format is XG-Y, where X is the data rate in gigabits per second (Gbps), and Y is the number of lanes or the modulation scheme used.
