    Double or Single-cladding Passive Fibre (GDF)

    YOFC double/single -cladding passive fibre is optimized precisely to match the DC-YDF series, with low splice performance. The fibre is widely used in industrial, medical and other fields. Large core and high NA multi-mode fibre can be used to pump source output and high power output.
    Applications
    • Pulse / CW fibre laser / amplifier
    • Pigtail
    • Fibre combiner
    • FBG
    Characteristics
    • Precise geometry
    • Low splice loss
    • Low NA core to maintain excellent beam quality
