Product Overview
As a new communication technology, satellite space laser communication is gradually becoming an important means to solve the communication needs on the earth. Compared with traditional microwave communication,satellite space laser communication has higher transmission rate, greater bandwidth and lower delay, so it has an important position in modern communication system. Space laser communication is an important technical approach to build space-based information network. Fiber lasers and amplifiers, as important components of inter-satellite and space observation and communication satellites,need to adapt to the working environment of multiple radiation sources in the universe.
Because space-borne components require extremely high environmental requirements, such as high shock vibration, thermal vacuum, radiation resistance, etc. Therefore, the space-borne optical fiber amplifier also needs to carry out the corresponding special design and production process; The radiation resistant fiber amplifier developed and produced by our company has rich experience in the research and development of radiation resistant optical devices, thermal control and aerospace grade electricity after years of accumulation and continuous technological upgrading. Developed and introduced radiation resistant, high-power and low-noise integrated amplifier to the market, aiming to greatly improve the performance of space optical transmission system and create a better cost performance for the optical part of customers, and provide efficient and reliable optical path solutions for space optical communication, inter-satellite communication, and satellite-based communication systems.

Radiation resistant,high power and low noise integrated amplifier module, integrates high power EYDFA and low noise EDFA in one,the product output up to 36dBm, power consumption< 30W@full temperature 36dBm.Through the anti-irradiation technology combining active and passive, the total anti-irradiation dose of the product ≥40krad,which still maintains excellent working performance indicators in the space irradiation environment.Compact design,module volume up to 180*160*32mm.
