Uncooled Operation of 53-Gbaud PAM4 EA-DFB Lasers in the Wavelength Range of 1510-1570 nm for 800-GbE Applications

摘要

53-Gbaud EA-DFB lasers—with four wavelengths in the 1500-nm region-for 800-GbE applications were developed. They demonstrated uncooled 53-Gbaud PAM4 operation with a TDECQ of lower than 2.5 dB over a wide temperature from 20 to 85°C.
