980/1064nm PM Fiber Isolator+ WDM Hybrid
Description
The Polarization Maintaining Isolator Wavelength Division Multiplexer combines a WDM and polarization maintaining isolator into a single compact package. It has high extinction ratio, low insertion loss and high isolation. The component is ideal for fiber amplifier and fiber optic system. The PM IWDM has ´ both axis working´ and ´slow axis working´ to be selected.
