This end-to-end experience allows us to focus on what matters most to long-term customers: consistent quality, reliable performance, and predictable results across batches. At the same time, our team provides continuous technical support to ensure smooth integration and long-term reliability.We are not a one-time product supplier, but a long-term partner committed to reducing after-sales issues, maintaining supply stability, and supporting sustainable business growth. This approach enables our customers to operate with confidence and build reliable, repeatable solutions for their markets.
Production Capacity
We currently operates 10 fiber Bragg grating production lines, covering major manufacturing stages including FBG writing, testing, packaging, and component assembly. The production facilities are configured with advanced imported equipment from Germany and Japan, supporting batch production and the manufacturing of various types of fiber Bragg grating products.
In key process stages, the production and testing workflow is equipped with German MLI excimer laser systems, YOKOGAWA optical spectrum analyzers, Ibsen photonics phase masks from Denmark, and Fujikura fusion splicers from Japan. These systems are applied to FBG writing, spectral measurement, grating period control, and fiber splicing processes, covering the main manufacturing flow from grating fabrication to final inspection and packaging, and supporting the production of FBG products across different wavelength ranges, structures, and application formats.

We pride ourselves on delivering prompt, professional support that ensures our customers can maximize the performance and reliability of their fiber Bragg grating systems. Our global support network guarantees timely assistance wherever our products are deployed.
Quality Assurance
Quality Control
All products undergo 100% inspection before delivery, with key parameters verified against customer-defined requirements to ensure consistency and application readiness.At the same time, critical production processes are placed under direct technical control, rather than relying solely on routine manual operation. This reduces process variability and helps maintain stable quality across different batches and custom configurations.
In addition, advanced equipment from well-established brands is used to support stable and repeatable performance, enabling tight process control and long-term reliability in real operating environments,reduce quality risk and minimize after-sales concerns.
100% inspection before delivery
Every product is fully inspected against customer-defined specifications to ensure consistency, accuracy, and application readiness before shipment.
Technical control at critical processes
Key production steps are directly supervised and controlled by experienced technical staff to minimize variability and ensure stable quality.
Well-known Brands Equipment for Stable Performance
These systems ensure precise control and consistent quality across all key FBG production stages, from grating writing and spectral measurement to final inspection and packaging.
