Project Description

980/1064nm Filter WDM

The 980/1060nm Filter Wavelength Division Multiplexer is based on environmentally stable thin-film filter technology. The devices combine or separate light at different wavelength in a wide wavelength range. They offer very low insertion loss, low polarization dependence, high isolation and excellent environmental stability. High power handling capability can be achieved through unique pigtail processing and high quality AR coating. These components have been extensively used in EDFAs, Raman amplifiers, WDM networks and fiber optical instruments.

  1. above specifications are for device without connector. All parameters are tested at room temperature.
  2. For devices with connectors, IL will be 0.3dB higher, RL will be 5dB lower. Power transmits through the connector less than 2W.
  3. For >10W high power applications, we will use heat sink package, contact DK Photonics for details.
  4. If there is pulse application, please be sure to inform us of pulse energy and peak power.

Package Dimension

*Due to ongoing design improvements, the package size is subject to change. Please contact DK Photonics for confirmation.

Order information   P/N: FWDM-1X2-①-②-③-④-⑤

When you inquire, please provide the correct P/N number according to our ordering information, and attach the appropriate description would be better. If need any connector, we do not recommend choosing a 250μm bare fiber pigtail.
