Frequency combs are derived from a single light source. >Current fibre optic communication systems owe their high-capacity abilities to the wavelength-division multiplexing (WDM) technique, which combines data channels running on different wavelengths, and most often requires many individual lasers. Optical frequency combs, with equally spaced coherent comb lines derived from a single source, have recently emerged as a potential substitute for parallel lasers in WDM systems[0](2021) So "These wavelengths are generated from an array of lasers, forming a frequency comb" is using "frequency comb" to mean something else in that sentence.
