Products

2000nm Tap Coupler/Isolator Hybrid Combination

DK Photonics’s 2000nm Tap Coupler/Isolator Hybrid Combination is a combination of a tap coupler and an isolator 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 hight return loss. 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
  • Communications
  • Laboratory R&D
