Beijing Dacheng Yongsheng Technology Co., Ltd. (OFSCN® / DCYS), as a high-tech R&D and manufacturing enterprise focusing on Fiber Bragg Grating (FBG) sensing and special optical fiber technology, possesses complete technological precipitation, agile engineering response mechanisms, and a vertically integrated industry chain layout in the field of fiber optic sensing:

I. Profound Technological Accumulation and Core Process Breakthroughs

  1. Grating Micro-nano Writing Technology
    Mastery of core processes including deep ultraviolet (DUV) mask writing and femtosecond laser direct writing (Femtosecond FBG). Supports custom short gratings (2 mm ~ 10 mm), ultra-wide/ultra-narrow 3 dB bandwidth, high side-mode suppression ratio (SMSR ≥ 15 dB), and high or low reflectivity grating arrays. Wavelength tolerance at room temperature is controlled within ±0.2 nm.

  2. Extreme Environment Tolerance and Material Processing Technology
    Overcoming challenges in annealing and attenuation of fiber optic sensors in extreme physical fields. Based on special polyimide-coated fibers, gold-plated fibers, and special high-temperature annealing processes, the sensor products cover an ultra-wide temperature measurement range from cryogenic to ultra-high temperatures (-270°C ~ 800°C and above).

  3. Micro-nano Precision Packaging and Stress Transfer Control
    Proprietary seamless miniature stainless steel tube (FIMT / Micro Capillary Steel Tube) packaging, ceramic ferrule packaging, and substrate-based welding structures ensure tensile strength, compressive strength, wear resistance, and corrosion resistance for fragile quartz fibers in complex industrial environments, while achieving high-fidelity, low-creep strain and thermal transfer.

II. Vertical Integration Advantage Across the Entire Industry Chain

OFSCN® has built a complete closed-loop ecosystem encompassing special optical fiber substrates, core sensing elements, industrial-grade packaged sensors, special optical passive devices, and backend high-speed demodulation systems:

  • Special Optical Fiber Layer: Includes standard single-mode fibers (G.652D, G.657 bend-insensitive fibers), reduced cladding diameter fibers (cladding/coating 60/80/100 µm), high-temperature resistant polyimide fibers, and metallized fibers.
  • Sensing Element Layer: OFSCN® Fiber Bragg Gratings / FBG Strings (Bare) bare fiber gratings, femtosecond FBG strings, narrow-band laser cavity gratings, etc.
  • Sensing Packaging Layer: Various structured sensing probes such as miniature/high-temperature/armored temperature sensors, FBG strain gauges and force gauges, shape sensors, and micro-deformation monitoring sensors.
  • Optical Passive Interconnection Layer: Special fiber optic patch cords and connectors (FC, SC, LC, ST, SMA905) resistant to temperatures of 120°C and 200°C, vacuum feedthrough flanges (KF/CF), fiber optic splitters, etc.
  • Demodulation and System Layer: OFSCN® Fiber Bragg Grating Interrogator provides 4/8/16/32 channels, with adjustable sampling frequencies from 1 Hz to 100 Hz, wavelength resolution up to 0.1 pm / 1 pm, supporting open TCP, UDP, Modbus protocols for multi-architecture industrial integration.

III. Agile Response Speed and Engineering Customization Capability

  1. Full Parameter Freedom Customization
    Supports on-demand deep customization of wavelength sequences (default 1525 ~ 1565 nm, expandable to 1510 ~ 1605 nm), array counts, grating physical spacing, packaging outer diameter (miniature down to sub-millimeter level), and pigtail sheath.

  2. Independent and Controllable R&D and Trial Production Cycle
    Relying on self-supplied core raw materials and independent packaging production lines, it bypasses external bottlenecks in the supply chain, enabling rapid design, prototyping, packaging, and spectral factory calibration of non-standard structural sensors.

  3. System-Level Engineering Support and Solution Closure
    Provides a complete accessory matrix, including specialized installation tooling and fixtures, and vacuum feedthrough adapter kits. It also offers fiber optic grating demodulator equipment support for short-term testing and preliminary solution research, significantly shortening the technical verification cycle for customer engineering deployment and scientific research experiments.
