The Optilab FOCS-1550-PG is designed for fiber optic current sensing. This device is composed of a polarizer, a Y-junction coupler and dual electro optic phase modulators. Based on Lithium Niobate (LiNbO3), FOCS-1550-PG is fabricated with Annealed Proton Exchange (APE) optical waveguides. The FOCS-1550-PG features Polarization Extinction Ratio (PER) exceeding 60 dB that can minimize bias drift which results from polarization crosstalk induced non-reciprocity. The FOCS-1550-PG assures high reliability and performance over wide temperature range, contact Optilab for more information.
