High Grade Polarization Maintaining (PM) 1x2 and 2x2 Fiber Optic Couplers & Optical Signal Splitters

   Gould's truly fused polarization maintaining (PM) fiber optic couplers and Optical signal splitters offer high extinction ratio (ER) with polarization launch into a single or dual axis (Slow axis & Fast axis). Gould utilizes our proven Fused Biconical Taper (FBT) process to manufacture high grade polarization maintaining couplers including single wavelength and wavelength flattened (Broadband/Wideband) (WFC). Our PM Components offer high extinction ratio with minimum optical loss. Gould utilizes PM fiber from different suppliers to accommodate your application specific operating wavelengths.
