980/1550 nm WDM/Isolator Hybrid Combination

DK Photonics' 980/1550nm 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

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

Applications

  • Fiber laser
  • Fiber amplifier
  • Fiber Sensor

  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.
