1550-nm Single-Mode Double Clad Fiber
High power 1550 nm amplifiers based on double clad Er/Yb fibers are widely used in CATV and Telecom applications. The 1550 nm passive double clad fiber is ideal for use both as a pump and signal output fiber in combiners and as a laser delivery fiber. The high cutoff, bend insensitive design of this fiber ensures excellent signal confinement, while allowing for low splice loss to Er/Yb doped double clad fibers and industry standard SMF-28™ fiber. They are available in both non-PM design for traditional high power amplifiers and in PANDA-style PM design for high power coherent communications and frequency conversion applications.
