    • 1540-1560nm PM Polarization Maintaining Bandpass Filter

    PM Band Pass Filter Idealphotonics' fiber filters use a special fiber structure to select or filter out specific wavelengths of light from different wavelengths. We can provide filter devices with different optical power versions according to user needs, which can be used in dense wavelength division multiplexing fiber communications, frequency division multiplexing fiber communications, spectrum testing, fiber sensors, fiber lasers and fiber amplifiers. If you need to customize the center wavelength, operating temperature or specific working bandwidth, please contact us for customization.

    产品特点High isolation 、Low insertion loss (0.7dB) 、High return loss (50dB) 、Excellent environmental stability 、High power handling capability
