10/200 Precision Matched
Passive LMA Double Clad Fiber
Nufern’s large mode area (LMA) passive double clad fiber is ideally suited for applications spanning military, industrial and
medical including linearly polarized fiber lasers and amplifiers. This fiber features a 10 micron diameter core and 200 micron
diameter clad size with a low NA (0.08) core. This fiber is precision matched to its active Yb-doped 10/200 LMA matched
counterparts to ensure excellent splice compatibility and low loss. As with all Nufern standard LMA fibers, this fiber is
proof-tested to 100 kpsi, an industry requirement for long term reliability. It utilizes the latest fiber design and features
NuCOAT-FA coating technology to ensure excellent preservation of beam quality and extended operating life demanded by
today’s industrial fiber laser applications.
Typical Applications
