产品描述

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 cut-off, 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.

Typical Applications

• CATV and Telecom amplifiers

• Laser delivery/fluorescence

Features & Benefits

• NuCOAT™ fluorocrylate coating – Greater fiber durability in extreme environmental operating & storage conditions

• Exceptional uniformity and core/clad concentricity — Low connectorization losses

• Bend insensitive — Survives application in tight confines

• All fiber proof tested to > 100 kpsi — Critical for ensuring long term reliability
