Abstract: Toward the realization of low-cost, long-, and extended-reach 400GbE data-center applications, the performance of pulse amplitude modulated (PAM) signals is studied using a state-of-the-art, high-performance 1.3-μm distributed feedback directly modulated laser, without any optical amplification… read more here.
