Polarization Maintaining Isolator WDM(PMIWDM)
The Polarization Maintaining Isolator WDM is a hybrid device that has functions of WDM and isolator in a single compact package. The PMIWDM is characterized with low insertion loss, high extinction ratio, high isolation, high return loss and excellent environmental stability and reliability. It is ideal choice for fiber amplifier application to combine signal and pump wavelength with stable signal isolation.
* Low insertion loss
* High extinction ratio
* High isolation
* Excellent stability and reliability
* Fiber lasers
* Fiber amplifiers
Polarization Maintaining Isolator WDM
IL over pass band @23℃
IL over reflection band
Extinction ratio (Only for Signal Port)
≥20(Type B) ≥23(Type F)
Isolation for signal @23℃
PM fiber for common & pass port;
PM fiber or SM fiber for reflect port
Ф5.5× L35 or Ф3.0× L30
Type B: Both axis working, Type F: for Fast axis blocked.
IL is 0.3dB (1310~1550nm) or 0.5dB (1064nm) higher, RL is 5dB lower and ER is 2dB lower for each connector added. The default connector key is aligned to slow axis.
