PM-DFA&EYDFA

High Power PM EDFA 1550nm 40dBm EDFA Optical Amplifier

Product
The PM EDFA (Polarization-Conserving Erbium-Doped Fiber Amplifier) is a specialized amplifier designed for polarization-conserving optical communication systems. It enables stable polarization state maintenance in long-distance, high-speed fiber transmission networks (e.g., 100Gbps and beyond), facilitating coherent detection. By detecting polarization state variations, it can sense external physical quantities. In quantum key distribution (QKD) systems, optical quantum states (including polarization states) serve as the fundamental information carriers.
● The power value can be 10W output for a single fiber;
● Light loss ratio>20dB
● Low power consumption
● Can be customized

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.
