摘要：
The erbium-doped fiber amplifier（EDFA）is a revolutionary breakthrough in the field of optical fiber communication，which makes long-distance，large-capacity，high-speed optical fiber communication possible. To realize long-distance transmission of optical fiber communication systems，it is inseparable from the corresponding optical fiber amplifier. However，with the explosive growth of transmission capacity demand，the existing DWDM communication system is facing huge pressure for capacity expansion. This paper systematically reviews the research progress of expanding the gain bandwidth to improve the transmission capacity，discusses the key issues involved in broadband active fibers and amplifiers，puts forward an understanding of ultra-broadband active fibers and their amplifiers in various bands，and provides a new perspective on future space division multiplexing based on few-mode multi-core fibers. © 2022 Chines Academy of Sciences.
