Project Description

980/1030nm & 980/1064nm Polarization Maintaining WDM/Isolator Hybrid Combination

DK Photonics’ WDM//Isolator Hybrid Combination is a combination of a wavelength division multiplexer and an isolator in a compact package. All input and output fibers are polarization maintaining. This product has an extremely low insertion loss, a very stable tap-coupling ratio, high isolation, and high return loss. This product offers integrated solution to EDFA application by combining more functions into a very compact package.

  1. Above specifications are for device without connector.
  2. 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.
  3. For this 1030/1064nm Isolator, Due to high IL, it is recommended to use average power of <300mW for 1064nm and <100mW for 1030nm. If you need higher handle power, please look for our TGG based High power isolator.
  4. If there is pulse application, please be sure to inform us of pulse energy and peak power.
  5. If you have questions about the axial direction, please contact us.
