Polarization Maintaining Filter Wavelength Division Multiplexer (GK-PMFWDM Series)

The PM FWDM series provides wavelength division multiplexing while maintaining signal polarization. The components are based on environmentally stable thin-film filter technology  and are characterized with high extinction ratio, low insertion loss, and high return loss. They are ideal for high speed WDM network systems.

    product description

    Wavelength Division Multiplexing: They can combine or separate optical signals at different wavelengths, enabling the transmission of multiple signals over a single optical fiber.

    Polarization preservation of signals: The PM FWDM series uses polarization maintaining fibers to ensure that the polarization state of optical signals is maintained during transmission, which is crucial for polarization sensitive applications.

    Environmentally stable thin film filtering technology: These wavelength division multiplexers use environmentally stable thin film filtering technology, which means their performance is not easily affected by environmental changes such as temperature and humidity fluctuations.

    High extinction ratio: High extinction ratio means that the suppression ability of optical signals is very strong at unwanted wavelengths, thereby reducing crosstalk between signals of different wavelengths.

    Low insertion loss: Low insertion loss refers to the minimal loss of signal strength when the signal passes through a wavelength division multiplexer, which helps maintain the integrity and quality of the signal.

    High return loss: High return loss means that there is very little light signal reflected back to the light source, which helps reduce noise and interference in the network.

    These characteristics make the PM FWDM series wavelength division multiplexer very suitable for high-speed WDM network systems, as they can improve the bandwidth utilization of the network, enhance the stability and reliability of signal transmission. These systems are typically used for long-distance transmission, metropolitan area networks, data center interconnection, and other application scenarios that require high bandwidth and low latency.
