Supplier
Shconnet
Part Number
SM-EYDF-6/125-HE
Category
Optical Fibers
Origin
China

Coherent/Nufern designs and manufactures erbium/ytterbium-codoped double-clad fibers using proprietary doping technology, with leading spectral performance. Volume production to tight standards and batch consistency meet CATV and telecommunications needs for stable high-power fiber amplifiers. EYDF-6/125-HE has a core composition for 915-976nm pumping; its optimized double-clad design provides high conversion efficiency, high output power and excellent long-term stability. Experimental slope efficiency exceeds 41% with 915nm pumping and reaches 44% with 976nm pumping. About 15m of fiber with 915nm pumping can readily produce an amplifier exceeding 2W.

Key Features

NuCOAT fluorinated coating technology improves fiber durability and reliability during operation and storage in extreme environments. A single-mode core design enables low-loss splicing to signal transmission fibers. Double-clad construction provides high-power performance and high power conversion efficiency. Optimized core composition provides high pump efficiency at 915-976nm. All fibers are proof-tested to >100kpsi, which is essential for long-term reliability when coiled. Tight mechanical and optical tolerances improve component manufacturing yield.
