1940nm Polarization Maintaining Tap Coupler/Isolator Hybrid Combination

DK Photonics’ 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 maintaining. 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.

Above specifications are for device without connector.
For devices with connectors, IL will be 0.3dB higher, RL will be 5dB lower and ER will be 2dB lower. The default connector key is aligned to slow axis. Power transmits through the connector less than 2W.
Type B: Both axis working, Type F: Fast axis blocked, the default is Type B if without request.
If there is pulse application, please be sure to inform us of pulse energy and peak power.
If you have questions about the axial direction, please contact us.

Package Dimension

PS: If Tap port is on the input side (Backward Tap), Tap is both axis working. If Tap port is on the Output side (Forward Tap), it is fast axis blocked, slow axis working. The default tap is on the input side.
