Key Features
20um core and 400um cladding; low-NA core design0.065. Tight physical tolerances for double-clad Yb-doped and passive delivery fibers. New coating technology and glass composition provide high output power, low photodarkening and excellent beam quality. Improved coating reliability in high humidity and longer service life at higher power support industrial requirements for power, environmental tolerance and reliability. The matched fiber series ensures splicing compatibility between fibers of the same specification. The latest NuCOAT-FA-HP-137A coating technology improves durability and reliability during operation and storage in extreme environments. New Coherent/Nufern glass compositions support higher continuous-wave output power. All fibers are proof-tested to ≥100kpsi, which is essential for long-term reliability when coiled.
