Smart Product Number: MM-EYDF-10/125-XPH
10/125 Erbium/Ytterbium-Doped Multimode Double Clad Fibers
Nufern's proprietary rare earth doping technology is used to deliver Er/Yb co-doped fibers with industry leading performance and reliability. These fibers feature 10 micron diameter core and a 125 micron diameter cladding with a 0.21 NA. The fiber design has been finely optimized to deliver the best performances for two distinct configurations. MM-EYDF-10/125-XP is designed to deliver ultra-high efficiencies while ensuring low threshold and high gain factors, ideal for CATV and telecom amplifiers. On the other hand, MM-EYDF-10/125-XPH is optimized to achieve tens of Watts of output power with high efficiency and suppressed 1 µm parasitic ASE, offering unmatched stability. The large core of the fiber allows for shorter fiber lengths in amplifier and laser systems to reduce the impact of non-linear effects. Utilizing Nufern's proprietary NuCOATFAcoating technology, these fibers offer the best damp and dry heat performance available and ensure extended operating lifetime.
