    Product Description

    The mini EDFA+VOA product from wseelaser combines the signal amplification capability of a miniaturized EDFA with the optical power adjustment function of a VOA (Variable Optical Attenuator), offering advantages like small size, high functional integration, and excellent performance:
    High Integration & Small Size The mini EDFA itself is highly integrated (size as small as 80*52*15mm). Integrating the VOA function maintains a compact structure, saving space, suitable for scenarios with strict volume requirements.
    Good Signal Amplification Performance Supports amplification of single-wavelength and narrowband signals across the full C-band. Provides effective gain with output power up to 20dBm or higher. Meets the need for power amplification of high-speed optical modules in transmission systems, ensuring signal strength after long-distance transmission and reducing signal attenuation.
    Flexible Optical Power Adjustment The VOA allows precise adjustment of optical signal power. Users can flexibly adjust power based on needs, optimizing power distribution within the optical path, preventing damage to optical components from excessive input power, and simulating different signal strength scenarios for testing and debugging optical communication systems.
    Low Noise Figure Inherits the low noise characteristic of the mini EDFA, with NF ≤ 5.5dB. Reduces noise introduced during amplification, ensuring signal quality and improving system Signal-to-Noise Ratio (SNR). Crucial for long-haul, high-precision optical communication and sensing systems.
    Low Power Consumption Features low-power design with low energy consumption. Helps reduce operating costs and heat generation, benefiting long-term operational stability and aligning with green energy trends.
    High Stability & Reliability Equipped with high-precision Automatic Temperature Control (ATC), Automatic Power Control (APC), Automatic Current Control (ACC), and Automatic Gain Control (AGC) circuits. Effectively controls pump output, ensuring stable operation across different ambient temperatures, reducing the impact of temperature variations on performance, and extending device lifespan.
    Convenient Management Provides communication interfaces (e.g., LVTTL, RS-232) and PC software for remote status monitoring, enabling automated control and data acquisition. Allows real-time viewing of amplification and attenuation status, facilitating management and troubleshooting for operators, improving work efficiency.
