High Power PM EDFA 1550nm 40dBm Optical Amplifier from China Suppliers and Factory for Polarization-Conserving Systems

,

Product Overview
Introducing the PM EDFA (Polarization-Conserving Erbium-Doped Fiber Amplifier), a cutting-edge solution for polarization-conserving optical communication systems. Manufactured in China, this specialized amplifier is engineered to ensure stable polarization state maintenance in long-distance, high-speed fiber transmission networks, supporting speeds of 100Gbps and beyond. Ideal for coherent detection, our amplifier can detect polarization state variations, making it suitable for sensing external physical quantities. In quantum key distribution (QKD) systems, it plays a critical role as optical quantum states, including polarization states, are the foundation of information transmission.
Key Features:
● High output power of up to 10W for a single fiber;
● Exceptional light loss ratio of >20dB;
● Energy-efficient low power consumption;
● Customizable options available as per client needs.
As a leading supplier and factory of advanced optical solutions in China, we are committed to delivering high-quality products tailored to your specific demands.

    Product description

    Furthermore, PM EDFAs provide high gain, effectively amplifying optical signals to meet long-distance transmission requirements. They also achieve high output power, with some models reaching up to 10 Watts, delivering sufficiently strong optical signals to extend transmission distance and coverage. Their key characteristic is a high Polarization Extinction Ratio (PER). This enables better separation of light signals in different polarization states, reducing polarization-dependent signal interference. In applications requiring high PER, such as fiber sensing, this enhances sensing accuracy and reliability.

    Frequently Asked Questions (FAQ)

    What is the primary benefit of the Polarization Extinction Ratio (PER) in PM EDFAs?
    A high Polarization Extinction Ratio (PER) enables better separation of light signals in different polarization states. This reduces polarization-dependent signal interference, which significantly enhances sensing accuracy and reliability in applications like fiber sensing.
    What is the operating wavelength range for this fiber amplifier?
    This PM EDFA operates within the C-band, specifically covering a wavelength range of 1540 nm to 1565 nm.
    What is the output power range and maximum power consumption of the device?
    The output power ranges from 20 dBm to 40 dBm (with certain models reaching up to 10 Watts of output power to extend transmission distance). The standard power consumption is approximately 80W.
    In which applications are PM EDFAs most commonly used?
    They are widely used in coherent optical communication systems, optical fiber sensing systems, quantum communication networks, high-precision measurement, scientific research, as well as military and aerospace applications.
    What are the standard dimensions and connector types for the M511 model?
    The M511 model features external dimensions of 200*142*25 mm and uses an FC/APC type fiber optic connector with a 1-meter input and output fiber length.
