SM-GDF-6/125-M
6/125 Precision Matched Passive Single-Mode 1550-nm Double Clad Fiber

Nufern’s precision matched single-mode passive double-clad fibers are available in two-versions — PANDA-style, polarization-maintaining (PM) and non-PM. These fibers feature a 6 µm core diameter and a 125 µm clad diameter optimized to match Nufern's active Er/Yb 6/125 µm fibers. This precise matching allows for the lowest splice loss improving performance for all applications including telecom optical amplifiers at 1550 nm. They utilize the latest fiber design and NuCOAT coating technology to ensure excellent preservation of beam quality and extended operating life demanded by today’s industrial fiber laser applications.
