YOEC Exhibits Advanced Optical Solutions at AISE 2026

YOEC Exhibits Advanced Optical Solutions at AISE 2026

From July 5 to 7, Wuhan Yangtze Optical Electronic Co., Ltd. (YOEC, SSE STAR Market: 688143) participated in the 4th International Commercial Aerospace Remote Sensing Satellite Application Conference & the 2nd International Aerospace Information and Satellite Industry Exhibition (AISE 2026) at the China National Convention Center Phase II in Beijing. At Booth 2005, YOEC presented its supporting technologies for inter-satellite optical communication, highlighting specialty optical fibers, thermal management solutions, and integrated industrial collaboration capabilities for commercial aerospace applications.

1. Radiation-Resistant Optical Fibers for Space Applications
Fiber optic gyroscopes (FOGs) are essential sensors for satellite attitude control. In the space environment, high-energy radiation can significantly increase fiber attenuation and polarization crosstalk, reducing the operational lifetime of satellites.
YOEC's 60/100 μm ultra-fine radiation-resistant polarization-maintaining (PM) fiber demonstrated outstanding performance during recent commercial satellite radiation testing. Under a radiation dose of 15 krad, the induced attenuation was only 1.2 dB/km, while at 60 krad it remained as low as 2.0 dB/km, exceeding the performance of comparable domestic products and reaching an internationally advanced level.
YOEC's radiation-resistant fiber portfolio has already been successfully deployed in multiple satellite programs, providing reliable optical transmission under harsh space environments and supporting the long-term stability of spaceborne optical systems.

2. Phase Change Thermal Management for Satellite Heat Control

As the power consumption of low Earth orbit (LEO) satellites continues to increase, efficient thermal management has become increasingly critical.
YOEC's aerospace phase change thermal management solutions utilize the latent heat storage and release characteristics of advanced phase change materials (PCMs), making them ideally suited for the intermittent operating conditions of satellites. The materials rapidly absorb heat during peak power operation and gradually release stored heat during low-power standby periods, effectively minimizing temperature fluctuations.
These solutions are designed for applications including:
Satellite platform thermal protection
Precision temperature control for optical communication payloads
Thermal management of onboard power systems
The technology enhances system reliability while supporting lightweight satellite design and extended mission life.

3. Building a Complete Inter-Satellite Optical Link Ecosystem

YOEC's strategic investment partner, Huanxin Yilian (Shanghai) Technology Co., Ltd., also exhibited its independently developed low-noise, high-power integrated Semiconductor Optical Amplifiers (SOAs) during AISE 2026. The products feature industry-leading noise figures and saturated output power.
Together, the two companies provide highly complementary capabilities:
YOEC focuses on specialty optical fibers, passive optical components, and system-level optical solutions.
Huanxin Yilian specializes in active optoelectronic devices, including semiconductor optical amplifiers.
This collaboration establishes a complete industrial chain covering:
Optical Fiber Materials → Passive Optical Components → Active Optical Amplification → Integrated Optical Equipment
By leveraging their respective expertise, both companies aim to jointly develop integrated photonic solutions for aerospace and underwater acoustic applications, accelerating product development while reducing supply chain risks.
Strengthening Commercial Space Industry Collaboration
Throughout the exhibition, YOEC's booth attracted significant attention from industry experts, customers, and business partners. The company's technical and sales teams engaged in in-depth discussions covering product reliability, environmental qualification testing, and customized development capabilities.
As China's low Earth orbit satellite constellation projects continue to expand, demand for supporting technologies for inter-satellite optical links is expected to grow rapidly. Building on the opportunities presented by AISE 2026, YOEC will continue strengthening collaboration across the industrial chain, expanding its portfolio of optical components, thermal management solutions, and optical amplifier technologies, while increasing R&D investment to provide reliable supporting technologies for the global commercial aerospace industry.
