7/130 Erbium/Ytterbium-Doped Double Clad Fiber PM
Nufern’s proprietary rare earth doping technology is used to deliver Er:Yb co-doped fibers with industry leading tolerances on the key spectroscopic parameters. This ensures the essential lot-to-lot reproducibility required for volume manufacturing of high power CATV and telecom optical amplifiers at 1550 nm. These fibers demonstrate high pump conversion efficiency and high power operation without rollover, enabled by the optimized double clad fiber design.
