Nufern’s high performance erbium-doped fiber capabilities are demonstrated in a unique erbium fiber product, SM-ESF-7/125. This fiber features a high erbium concentration (peak absorption 55 dB/m) and high pump conversion efficiency achieved with proprietary technology that delivers industry leading tolerances on the key spectroscopic parameters. The polarization maintaining version of this fiber, PM-ESF-7/125, is also available for applications that require a polarized signal.
