Project Description
1550nm Polarization Maintaining Tap Coupler/Isolator Hybrid Combination
DK Photonics’s 1550nm Tap Coupler/Isolator Hybrid Combination is a combination of a tap coupler and an isolator in a compact package. 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 EDFA 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.
- If there is pulse application, please be sure to inform us of pulse energy and peak power.
