LIEKKI® Tm1500-6/125DC(-PM)
LIEKKI® Tm1500-6/125DC(-PM) are highly doped Thulium-doped fibers with demonstrated good efficiencies at wavelengths of 2µm. The fibers are designed without pedestal and are available as both non-Polarization Maintaining and Polarization Maintaining versions. Passive fibers with matched mode field diameter are available in Q3 2025.
