Yangtze Optical Electronic Co., Ltd. (referred to as YOEC) is a publicly listed high-tech enterprise focused on optoelectronic technology. YOEC is mainly engaged in the R&D, manufacturing, and sales of products in five major fields including Special Optical Fibers and Cables, Special Optical Devices, Polymer Materials, High-end Equipment, and Optoelectronic Systems. We also provide customized services for various products to customers.
YOEC focuses on optical fiber coils for fiber optic gyroscopes and has built a complete inner-industry chain, holds multiple core technologies and invention patents, and offers solutions widely applied in aerospace, marine monitoring, smart grids, industrial lasers, new energy, and next-generation optical communications. Based on experience of more than ten years in fiber-coil production, the structure can be optimized according to customer optical path assembly requirements and using environment.
The panda polarization-maintaining optical fiber from YOEC, designed for fiber optic gyroscope coil, is primarily used in the sensitive coil of fiber optic gyroscope. This fiber enhances mechanical reliability, temperature stability, environmental adaptability, and radiation resistance to meet the demands of its application environment. The fiber's axial uniformity and batch consistency have been optimized. Additionally, the internal and external coatings use proprietary coating materials developed by YOEC, providing excellent stability across all temperature ranges, environmental adaptability, and mechanical reliability, making it suitable for operating temperatures from -50℃ to +105℃.
By converting sound and vibration signals into optical signals, sensitive coils of various types of optical fibers, optical fiber lengths, sizes and structures can be customized according to customer requirements, with the characteristics of high reliability, small size, low loss and etc.
YOEC bending insensitive single-mode fiber has the characteristics of small geometric size and bending insensitivity, which can maintain good Optical Properties under the condition of small bending radius, and can meet the requirements of small-size optical cables and optical devices. it is widely used in optical fiber hydrophone and other industries. The optical fiber can be specially designed according to the needs of users to meet the requirements of mode field diameter, cutoff wavelength and bending sensitivity. This series of optical fiber preform adopts in-tube chemical vapor deposition process, which has the advantages of low hydroxyl group, high numerical aperture and good optical uniformity.
The Y waveguide is an integrated optical component, formally known as a multifunctional integrated optical device based on lithium niobate (LiNbO₃). It is a key component in fiber optic gyroscopes, integrating the functions of a polarizer, beam splitter, and phase modulator. Together with the fiber coil, it forms a Sagnac interferometer.
The light source in a fiber optic gyroscope primarily provides the optical signal required to generate the Sagnac effect in the Sagnac interferometer.
This optical receiver module adopts a PIN photodetector with an InGaAs planar structure, featuring low noise, high sensitivity, and excellent hermetic sealing. It supports adjustable transimpedance gain to meet various application requirements.
This series optical module is an optical component applied to ultraminiature closed-loop fiber optic gyroscope (FOG) and also a special optical module that is fused and assembled by fiber-optic coils and optical devices (Y-waveguide, coupler, photodetector, light-source) in the order of gyroscope’s optical path. It can replace fiber-optic coil, Y-waveguide and other separated parts for direct modular installation on the gyroscope, thus simplifying the assembly process of the gyroscope.
This SLD module is designed for high-performance optical applications requiring broad bandwidth and high stability. It features a compact 8-pin butterfly package with a built-in thermoelectric cooler to ensure reliable operation over a wide temperature range.
