Doped Fibers

We offers a comprehensive range of erbium-doped and specialty fibers designed for high-performance amplification in telecommunications, LiDAR, medical imaging, space applications, and high-power laser systems.

IsoGain™ Erbium-Doped Fiber – Industry-leading efficiency for EDFAs, LiDAR, and OCT. Available with signal absorption from 5dB to 45dB and supports pump power up to 800mW. Covers both C-Band and L-Band, with Mini and Micro EDFA options featuring reduced cladding diameters.

AstroGain™ Erbium-Doped Fiber – Designed for space-based light sources and amplifiers, this fiber supports core-pumped power up to ~400mW with an optimized trivalent core matrix for reliable performance in extreme conditions.

PM Erbium-Doped Fiber – Ideal for coherent communications and polarization-sensitive EDFAs, supporting 980nm pumping and offering polarization extinction levels up to -30dB for superior signal integrity.

Triple-Clad Doped Fiber – All-glass cladding-pumped fiber for high-power EDFAs (YEDFAs), supporting pump power beyond 5W. Its round glass design simplifies cleaving and splicing, ensuring efficient integration.

Dual-Clad Erbium/Ytterbium Doped Fiber – High-power all-glass fiber optimized for up to 5W pump power. Featuring Fibercore’s petal-shaped secondary cladding, this fiber maximizes energy transfer efficiency, while its round design simplifies handling and integration.

Isolating Wavelength Division Multiplexer (CP-IWDM) – Designed for cladding pump applications
