    Product description

    The (2+1)*1 Combiner is a device that combines 2 pump lights and 1 signal light into a single double-clad fiber. It is primarily used in high-power fiber lasers and fiber amplifiers. Its product features are:
    • Low Insertion Loss: Signal insertion loss is typically low, generally ≤0.4dB. Reduces optical signal energy loss during combining, maintaining signal strength and improving overall system efficiency.
    • High Pump Efficiency: High pump efficiency, typically ≥93%. Effectively couples pump light energy into the signal light, enabling efficient transmission of pump and signal light within the same fiber.
    • Broad Wavelength Range: Adapts to a wide wavelength range. Pump wavelength range generally 780-1000nm, signal wavelength range 1530-1575nm. Meets the needs of different types of lasers and amplifiers.
    • High Power Handling: Single-arm power handling capability up to 45W. Applicable in high-power fiber laser systems, suitable for high-power operating scenarios.
    • High Return Loss: Return loss typically >45dB. Effectively reduces optical signal reflection, minimizing interference from reflected light, and improving system stability and reliability.
    • Good Polarization Characteristics: For polarization-maintaining (PM) types, Polarization Extinction Ratio (PER) ≥18dB. Maintains the polarization state of the signal light, meeting application scenarios requiring specific polarization特性, such as PM fiber lasers.
    • Strong Environmental Adaptability: Operating temperature range -20°C to 70°C, storage temperature -40°C to 85°C. Good environmental adaptability enables stable operation under different conditions.
    • Customizable: Can provide custom configurations based on user requirements, including fiber type, port configuration, etc., meeting specific application needs of different users.
