High Isolation WDM
Product ID: W-HI

High Isolation WDM

FOCI's High Isolation WDMs are ultra reliable devices featuring high isolation, low insertion loss, and high port isolation over wide ranges of temperature and wavelength. The High Isolation WDMs are designed to divide and/or combine different optical wavelength in optical amplifiers. With its innovative Fused Biconical Taper (FBT) process, FOCI's W-HI series High Isolation WDMs have proven to provide exceptional characteristics for all applications demanding critical performance. Available in a wide variety of packaging configurations, these W-HI series are operable in 1310/1550nm, 1310/1650nm, or 1550/1650nm wavelength ranges. Various types of pigtailing and connector terminations are available to meet your requirements.
