DCF-EY-10/128H-G2 at a glance

Key specifications

  • 2.4 ± 0.4

    Cladding Absorption @ 915 nm (dB/m)

    High absorption – minimizes fiber length and reduces nonlinearities.

  • 10 ± 1

    Core Diameter (µm)

    Diameter of the light-guiding core.

  • 0.20 ± 0.02

    Core Numerical Aperture

    Light-acceptance angle of the core; with the core size, it sets how many modes are guided.

  • 128 ± 3

    Cladding Diameter (µm)

    Outer diameter of the glass cladding.

  • Min 0.45

    Numerical Aperture - Cladding

    High optical efficiency, minimizing pump power requirements.

  • 85 ± 25

    Core Absorption @ 1535 nm (nominal) (dB/m)

    Light absorbed per metre by the doped core at the stated wavelength.

Description

Our new generation of Erbium/Ytterbium co-doped fiber offers high absorption and efficient energy transfer for high performance operation in the 1.5 μm region.
