Recently, with the development of newgeneration mobile communication systems, the demand for high data rates and large bandwidth is increasing. In this study, we proposed a secondorder Raman fiber amplifier designed with two secondorder pumps and four firstorder pumps to amplify the C+L fullband signal light using a telluriumbased optical fiber as the transmission medium, which can effectively alleviate optical communication network challenges due to bandwidth growth. First, a simplified secondorder Raman coupled wave equation is solved numerically, and then the pumping parameters of the secondorder Raman fiber amplifier are optimized using a cooperative search algorithm to improve output performance. Meanwhile, the performance of firstand secondorder Raman fiber amplifiers under the same pump parameter configuration is analyzed. Additionally, the influence of two key factors, that is, secondorder pump optical power and fiber length on the average output gain and gain flatness of a designed secondorder telluriumbased Raman fiber amplifier are investigated. Experimental results show that the average output gain of the designed secondorder telluriumbased fiber Raman amplifier is 27. 3601 dB and the gain flatness is 0. 6601 dB in the ultrawide bandwidth range of 1530-1630 nm.
