  1. This product is suitable for broadband light sources, if laser have narrow line width, it should choose our optical depolarized module.
  2. Above specifications are for device without connector.
  3. For devices with connectors, IL will be 0.3dB higher, RL will be 5dB lower and ER will be 2dB lower. The default connector key is aligned to slow axis. Power transmits through the connector less than 2W.
  4. For >10W high power applications, we will use heat sink package, contact DK Photonics for details.
  5. 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: ILDP-①-②-③-④-⑤-⑥

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.
