The cost-effective, compact, and energy-efficient amplifier boasts a bandwidth of 300 nanometers, enabling it to transmit ten times more data per second.
From the abstract: “we obtained a continuous-wave gain bandwidth of 330 nm in the near-infrared regime. […] Furthermore, we realized wide all-optical wavelength conversion of single-wavelength signals beyond 100 Gbit s−1 without amplifying the signal and idler wave.”

I think figure 4 from the PDF shows it the best. Their amplifier covers 1400 nm to 1700 nm infrared lasers.
