Erbium Doped Fibre (EDF)

YOFC offers full series of erbium doped fibres, which could meet the most stringent amplifier requirements both for C-band and L-band. Through 1480nm or 980nm pump technology, YOFC erbium doped fibre can realize 35nm amplification bandwidth, and maintain flatness gain to get ideal power conversion efficiency. YOFC erbium doped fibres is specially designed for high performance, low noise requirements amplifier, for example: optical preamplifier, booster and in-line amplifier in the WDM communication system. YOFC erbium doped fibre has been optimized through co-doping with erbium and aluminum technology to ensure the high quality performance.
