980/1030nm SM WDM/Tap Coupler Hybrid Combination

DK Photonics' 980/1030nm WDM/Tap Coupler Hybrid Combination is a combination of a wavelength division multiplexer and tap coupler in a compact package. All input and output fibers are polarization independent. 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 amplifier application by combining more functions into a very compact package.

Features

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

Applications

  • Fiber laser
  • Fiber amplifier
  • Fiber Sensor
  • 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 transmits through the connector less than 2W.
  3. If there is pulse application, please be sure to inform us of pulse energy and peak power.
