    Product Details

    Product Description

    The Erbium-Ytterbium Co-doped Fiber Amplifier (EYDFA) is a high-performance optical amplification device that combines the advantages of Erbium (Er³⁺) and Ytterbium (Yb³⁺) ions, exhibiting unique product features across various fields:
    High Power Output Capacities of output power range from several Watts to tens of Watts, meeting the demand for strong signals in high-power laser systems and long-haul optical communication.
    Flexible and Integrable Design
    Excellent Operational Stability and Reliability Equipped with high-precision Automatic Temperature Control (ATC) and Automatic Power Control (APC) circuits. These adjust operating parameters in real-time to ensure stability of output power, gain, and other metrics (power stability typically within ±0.1dB) despite ambient temperature changes or input signal fluctuations. Furthermore, the use of highly reliable pump sources and premium fiber materials results in a long Mean Time Between Failures (MTBF), suitable for continuous long-term operation.
    Wide Applicability and Strong Adaptability Beyond traditional communication fields like long-haul trunk lines and metropolitan area networks (MANs), EYDFAs also meet the demand for high-power, high-stability optical amplification in specialized scenarios such as industrial laser processing, medical equipment, and fiber sensing networks, offering strong environmental adaptability and application scalability.

    Frequently Asked Questions (FAQ)

    What is the primary function of an Erbium-Ytterbium Co-doped Fiber Amplifier (EYDFA)?
    An EYDFA is a high-performance optical amplification device designed to provide high power output by co-doping Erbium (Er³⁺) and Ytterbium (Yb³⁺) ions. It is ideal for high-power laser systems, long-haul optical communication, and specialized fiber sensing applications.
    What is the wavelength coverage and typical output power of this device?
    This EYDFA operates within the C-band wavelength coverage of 1540 nm to 1565 nm. It delivers a maximum saturated output optical power of up to 37 dBm (with options starting from 23 dBm).
    How does the system maintain stability under varying conditions?
    It features integrated, high-precision Automatic Temperature Control (ATC) and Automatic Power Control (APC) circuits. These monitor and adjust parameters in real-time, keeping output power stability within ±0.1dB despite input fluctuations or external temperature variations.
    What are the power supply and communication requirements?
    The typical supply voltage is 5V or 12V (operating within ranges of 4.75/11.75V to 5.25/12.25V) with a total power consumption of 30W. It supports LVTTL/RS232 communication levels for control and monitoring.
    What environmental conditions can the EYDFA tolerate?
    The module has a working temperature range of -5°C to +55°C, a storage temperature range of -40°C to +85°C, and can operate in non-condensing relative humidity levels between 5% and 85%.
