980/1064nm WDM/Tap Coupler/Isolator Hybrid Combination

DK Photonics’s 980/1064nm WDM/Tap Coupler/Isolator Hybrid Combination is a combination of a wavelength division multiplexer, tap coupler and an isolator in a compact package. All input and output fibers are polarization independent. This product has an extremely a very stable tap-coupling ratio, high isolation, and hight return loss. This product offers integrated solution to fiber amplifier application by combining more functions into a very compact package.

Features

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

Applications

  • Fiber laser
  • Fiber amplifier
  • WDM Systems
  • Fiber optic Instruments
  • 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.
