980/1550nm SM WDM/Tap Coupler Hybrid Combination

DK Photonics’ 980/1550nm 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
  • LowPDL
  • High stability and reliability

Applications

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