title = "Optimization of EDFA position for high speed short reach PAM4 optical fiber communication systems",
abstract = "In this paper, the position of erbium-doped fiber amplifier (EDFA) in an intensity-modulation and direct-detection (IM/DD) optical fiber communication system is optimized to suppress a part of chromatic dispersion (CD) caused distortions and alleviate the burden of digital signal processing. The results demonstrate that, for a system with a certain signal rate and launch optical power, the transmission fiber length is longer with optimizing the position of the EDFA. If a 20\% overhead soft-decision forward error correction threshold of 2.7×10-2 is considered, the CD-uncompensated transmission fiber length of a 50 Gb/s four-level pulse amplitude modulation (PAM4) system can be increased by 34.78\% compared with the non-optimized system. Moreover, the launch optical power of the optimized system can be decreased by 6 dB.",
