Exceptionally Stable and Reliable

General Details

Characteristics

    • High Return Loss
    • Low Insertion Loss

    The Polarization Maintaining Filter Coupler is manufactured by using advanced technology to allow the input signal to be splitted at various ratios with high extinction ratio. It supports both polarizations.

    PM Filter Coupler Module

    • Compact High Performance
    • High Extinction Ratio
    • Low Insertion Loss

    This Product series is manufactured by using advanced technology to allow the input signal to be splitted into multichannels at a given splitting ratio with high extinction ratio, low excess loss, low uniformity, low WDL and low TDL. It can be widely used in fiber sensors, amplifiers, lasers, etc.
