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

    Polarization Maintaining (PM) Patchcords are specialized fiber optic cables designed to preserve the polarization state of light as it travels through the fiber. This is crucial for applications where the polarization properties of the light are important, such as in certain types of fiber lasers, optical amplifiers, and test instrumentation. Here are the key features and benefits of the Polarization Maintaining Patchcord series:

    Wavelength Division Multiplexing: The PM FWDM series allows for the transmission of multiple signals at different wavelengths over a single fiber, increasing the bandwidth and efficiency of the network.

    Polarization Maintenance: These devices are designed to maintain the polarization state of the light signals as they are multiplexed and demultiplexed, which is essential for systems where polarization-sensitive components are used.

    High Extinction Ratio: The extinction ratio is a measure of the ability to differentiate between the multiplexed signals. A high extinction ratio in PM FWDM devices means that the system can clearly distinguish between the different wavelength channels, reducing crosstalk and improving signal quality.

    Low Insertion Loss: Low insertion loss in the PM FWDM series ensures that the power of the light signals is maintained as they pass through the device, minimizing signal degradation and preserving signal strength.

    High Return Loss: A high return loss indicates that minimal light is reflected back into the system, which helps to reduce interference and maintain signal integrity.
