Abstract
Injection locked quantum-dash laser diode-based frequency-comb source is employed in wavelength-division multiplexed (WDM) transmission in ~1610nm L-band. An aggregate data rate of 192 Gbits/s (3×16 GBaud-DP-QPSK) is demonstrated over three channels separated by 50 GHz in coherent transmission over a 10 km-long single-mode fiber.
