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.
