DCF-EY-10/128H

Description

This Erbium/Ytterbium co-doped fiber offers a high doping concentration and efficient energy transfer for operation in the 1.5 μm region. With its high absorption, this product is an excellent choice for the design of high-power optical amplifiers (>5 W) used in various markets such as CATV in telecom or low-power LiDAR.

Features & Benefits
  • High doping concentration – provides highly efficient energy transfer, minimizing pump power requirements
  • High absorption – minimizes fiber length and reduces nonlinearities
  • Optimized Er/Yb core composition – reduces 1 µm parasitic emission
Applications
  • High-power telecom amplifiers
  • Low-power fiber lasers and optical amplifiers
  • Sensing: LiDAR and spectroscopy
