Application Information

Award Applied For:

Weike Cup·OFweek 2026 Optical Industry Annual Innovation Product Award

Product Name:

Radiation-Resistant Erbium-Doped and Erbium-Ytterbium Co-Doped Fibers

Product Launch Year/Development Background:

In response to the accelerating global demand for satellite internet construction, YOFC initiated the development of radiation-resistant active fibers in 2024 and jointly launched radiation-resistant erbium-ytterbium co-doped fibers and radiation-resistant erbium-doped fibers in 2025.

Product Description:

Radiation-resistant erbium-doped and erbium-ytterbium co-doped fibers are the core gain media for satellite-based fiber amplifiers. In practical application environments with radiation, traditional erbium-doped and erbium-ytterbium co-doped fibers, which contain more radiation-sensitive dopants, experience a sharp increase in radiation-induced losses due to defects, leading to a decline in fiber gain performance and the inability to achieve signal amplification and output. These optimized fibers reduce radiation-induced defects through innovative dopant design, drawing processes, and post-treatment techniques, ensuring excellent gain performance while enhancing radiation resistance. Additionally, a dual-coating structure provides superior mechanical and environmental reliability. Depending on customer needs, high or low absorption, polarization-maintaining or non-polarization-maintaining, and single-mode or multi-mode products can be provided or customized.

Key Innovation Points:

The key innovation of radiation-resistant erbium-doped and erbium-ytterbium co-doped fibers lies in optimizing radiation resistance by minimizing radiation-induced defects.

This product achieves innovation through dopant development: on one hand, experimental evaluations reduce the doping concentration of radiation-sensitive components, lowering fiber losses in the absorption and emission bands of active fibers; on the other hand, utilizing dopant elements with variable valence characteristics, it absorbs electrons and holes generated by radiation, enabling ion valence changes and significantly reducing the concentration of radiation-induced defects.

Furthermore, by leveraging the competitive relationship among various co-dopants in forming radiation-induced defects, the generation of critical defects is further reduced. As the number of dopants increases, fiber losses also rise. The dopant design of radiation-resistant erbium-doped and erbium-ytterbium co-doped fibers must balance high gain performance with excellent radiation resistance.

Reasons for Participation:

This product focuses on optimizing the radiation resistance of active fibers, precisely meeting the market demands of satellite internet construction. Through innovative designs in dopant composition, drawing processes, and post-treatment techniques, it significantly enhances the gain performance of active fibers in radiation environments. Under the premise of ensuring excellent gain performance, multiple radiation tests confirm that the radiation-resistant erbium-ytterbium co-doped fiber achieves a gain attenuation of only 0.13 dB under a total radiation dose of 100 krad, while the radiation-resistant erbium-doped fiber achieves a gain attenuation of only 0.6 dB under the same conditions, demonstrating internationally leading radiation resistance. With stable platform resources and process technologies, it ensures consistent and reliable fiber performance, supporting satellite internet construction and driving industry quality improvements.
