New Touch Screen Model Fiber Amplifier 25dBm TDFA
This product uses advanced semiconductor laser pumping and rare earth gain fiber, combined with a dedicated integrated circuit chip, to achieve high stability, high gain, and low power consumption. The laser is coupled and output through a single-mode fiber, and the method of use is simple. It can be widely used in tests and experiments in the fields of optical communication, fiber laser, and fiber sensing.
Thulium-doped fiber amplifier (TDFA for short) can be used to amplify 2μ band laser signals in the power range of -10dBm~+10dBm. The saturated output power can reach up to 40dBm, and it is often used to increase the emission power of laser light sources. Desktop TDFA is convenient for experimental operation. Users can set parameters through the front panel. It can also provide more compact modular products to facilitate system integration.
Both desktop and modular TDFA can support host computer software control or serial port command control. Users can choose the TDFA model with appropriate parameters according to their own needs to achieve the best amplification effect. We can also provide customized products according to the specific needs of customers.

Unlocking High-speed Transmission: In-depth Analysis of 40dBm Single-mode YDFA Technology
Ytterbium-doped fiber amplifier (YDFA) generates gain by pumping ytterbium-doped fiber with semiconductor laser and is used to amplify optical signals in the 1030~1080nm band. The output power is continuously adjustable and has the advantages of high gain and low noise. The desktop YDFA is convenient for experimental operation, and the user can adjust the pump current and output power through the panel buttons. A more compact modular YDFA is also provided to facilitate user system integration.
With the rapid development of optical communication technology, how to effectively enhance the intensity of optical signals and extend the transmission distance has become the focus of the industry. As an important technological innovation in this field, the ytterbium-doped fiber amplifier is gradually becoming a key device in the construction of optical communication networks with its excellent performance and broad application prospects.
The 40dBm ytterbium-doped fiber amplifier uses advanced ytterbium-doped fiber as the gain medium. Ytterbium is widely used in fiber amplifiers due to its unique energy level structure and efficient energy conversion characteristics. When pump light (usually high-power laser) is injected into ytterbium-doped fiber, ytterbium atoms absorb the energy of the pump light and undergo energy level transitions. Subsequently, when the optical signal passes through the fiber, the ytterbium atoms are stimulated to radiate photons of the same frequency as the signal light, thereby amplifying the optical signal.
It is a 1030~1070nm Ytterbium-doped fiber amplifier. The saturated output power is 40dBm @0dBm input. The 40dBm YDFA is a high-power amplifier, with an additional Monitor interface. The Monitor is used to monitor or synchronize signals with low power. And it has built-in cooling fan. Configured with RS2323 interface, available software or control command YDFA.
It supports two working modes of APC/ACC, and the two working modes can be switched by pressing the button. In APC working mode, the output power can be set. In ACC working mode, the working current can be set. Finally, press the middle square button to confirm.
The use of single-mode optical fiber as the transmission medium ensures high-quality transmission of optical signals. Single-mode optical fiber has small intermodal dispersion and is suitable for long-distance, high-speed optical communication applications.
