The PM Tap+Isolator+WDM device is campact hybrid components built by PM Panda fiber or other customized fiber which provides fuction as a WDM with an optical isolation and a tap coupler integrated. Froward pump type and backward pump type are both available. The PM WDM/Tap/Isolator are characterized with low insertion loss, high extinction ratio, high return loss and high isolation. It has been widely used in EDFA, optics cutting, pump laser and research.
