This single-mode thulium-doped fiber fully complies with telecom standards, making cleaving and splicing straightforward. Its no-pedestal design eliminates parasitic modes and residual multimode propagation. Featuring a high cladding absorption at 790 nm and an optimized core composition to enhance the cross-relaxation process, makes it ideally suited for high-power optical systems demanding superior performance.
