Polarizer WDM679nm/707nm10 mW

PM Polarizer Wavelength Division Multiplexer 679 nm 707 nm 10 mW
The PM Polarizer Wavelength Division Multiplexer is a high-performance polarization-maintaining fiber optic device designed for quantum communication applications, integrating polarization control and wavelength division multiplexing. It operates at 679 nm and 707nm,, supporting up to 10 mW optical power. Features include a high extinction ratio (≥20dB),), low insertion loss (≤1.5dB),), and high isolation (≥25dB).). Built with PM Panda fiber design for stable polarization state transmission. Ideal for quantum key distribution (QKD), quantum entanglement sources, single-photon sources, and quantum communication systems. Compliant with Telcordia GR-1209-CORE and GR-1221-CORE standards; RoHS certified.
