摘要

随着网络业务流量的增长，通信业务对密集波分复用（DWDM）的性能要求越来越高。为了提高传输效率，传输频谱逐渐向C+L Band传输扩展，Super C Band传输应运而生，但目前与之对应的掺铒光纤放大器（EDFA）相关研究较少。针对这一问题，文章提出了一种针对Super C Band传输的EDFA结构，基于Giles模型，分析了EDFA在Super C Band的特性，利用多级泵浦机制，设计了一种可以在Super C Band范围内进行放大的EDFA。结果表明，在-9.3 dBm入光时，该EDFA可以实现26 dB的平坦增益，16.7 dBm的输出功率，此时噪声指数小于5 dB，Ripple小于0.1 dB。并且根据需要，在入光处于-15.0～-3.5 dBm范围内时，通过调节泵浦功率与可调衰减器，均能够实现7～26 dB的可调增益。该EDFA可应用于5G传输和数据中心之间光纤通信等场合。

Abstract

With the growth of network traffic

communication services have higher and higher requirements on the performance of Dense Wavelength Division Multiplexing (DWDM). In order to improve the transmission efficiency

the transmission spectrum gradually expands to the C+L band transmission

and Super C Band transmission emerges as the times require. In order to solve this problem

this paper proposes an Erbium-Doped Fiber Amplifier (EDFA) structure for Super C Band transmission. Based on the Giles model

the characteristics of the EDFA in Super C Band are analyzed. A multi-stage pumping mechanism is used to design an EDFA that amplify in the Super C Band range. The results show that the EDFA can achieve a flat gain of 26 dB and an output power of 16.7 dBm when the light is incident at -9.3 dBm. The noise figure is less than 5 dB

and the ripple is less than 0.1 dB. And according to the requirement

when the incident light is in the range of -15～-3.5 dBm

the adjustable gain of 7～26 dB can be achieved by adjusting the pump power and the value of Variable Optical Attenuator (VOA). The EDFA can be used in the area of 5G transmission

optical fiber communication between data centers

etc.
