C-Band Erbium Doped Fibre
YOFC's C-band erbium doped fibre (EDF) is designed for single-channel and multi-channel fibre
amplifiers, ASE light sources, optical communication DWDM transmission networks, and CATV
networks with optimized EDFA modules. Our C-band EDF features excellent consistency and
stability. We offer a range of EDF products with different absorption coefficients and cladding
diameters. Through mature process control and rigorous testing methods, we guarantee
exceptional performance, including high conversion efficiency, precise shape of the erbium gain
spectrum, and excellent lot-to-lot consistency between groups of products. Thus, the EDF
products can meet the strict demands of EDFA applications.
