980/1064nm WDM/Isolator Hybrid Combination

DK Photonics’s 980/1064nm WDM/Isolator Hybrid Combination (WIH) is a combination of a WDM Filter and a polarization insensitive optical isolator. The WIH is a low-cost model with excellent performance including low insertion loss, high isolation, high return loss, low polarization dependent loss (PDL), and low polarization mode dispersion (PMD). This product offers integrated solution to fiber amplifier application by combining more functions into a very compact package.

Features

  • Compact Size
  • High channel Isolation
  • High stability and reliability
  • Epoxy free on optical path

Applications

  • Fiber laser
  • Fiber amplifier
  • Communications
  • Laboratory R&D

  1. Above specifications are for device without connector.
  2. For devices with connectors, IL will be 0.3dB higher, RL will be 5dB lower.Power transmitsthrough the connector less than 2W.
  3. Forthis 1064nm Isolator,Due to high IL, it is recommended to use average power of <200mW. 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.
