The LBTEK polarization-maintaining single-mode wavelength division multiplexer is a passive optical device used in polarization-maintaining fiber transmission systems to separate or combine light of two different wavelengths. It features high extinction ratio, low insertion loss, high isolation, and high return loss. The fibers are all protected with 900 μm loose tube sleeves. Currently available in various center wavelength combinations of 980 nm-1550 nm, with FC/UPC and FC/APC connector options. Each wavelength division multiplexer undergoes rigorous testing and comes with a test report to ensure product performance.
