DCF-EY-6/128

Description

This Erbium/Ytterbium co-doped fiber offers a high doping concentration and efficient energy transfer for operation in the 1.5 μm region. As this fiber allows single-mode operation and provides excellent beam quality, it is ideal for the design of low-power optical amplifiers used in various markets such as CATV in telecom or low-power LiDAR.

Features & Benefits
  • Single-mode operation – provides excellent beam quality
  • High doping concentration – provides highly efficient energy transfer, minimizing pump power requirements
  • Optimized Er/Yb core composition – reduces 1 µm parasitic emission
Applications
  • High-power telecom amplifiers
  • Low-power fiber lasers and optical amplifiers
  • Sensing: LiDAR
