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

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-period gratings ( 2\text{ mm} \sim 10\text{ mm} ), ultra-wide/ultra-narrow 3\text{dB} bandwidths, high side-mode suppression ratios ( \text{SMSR} \ge 15\text{ dB} ), and high or low reflectivity grating arrays. Wavelength tolerance at room temperature is controlled within \pm 0.2\text{ nm}.

  2. Extreme Environment Tolerance and Material Processing Technology
    Overcame the annealing and attenuation challenges of fiber optic sensing in extreme physical fields. Leveraging specialty polyimide-coated fibers, gold-plated fibers, and special high-temperature annealing processes, the temperature range for sensing products covers extremely low to ultra-high temperatures ( -270^\circ\text{C} \sim 800^\circ\text{C} and above).

  3. Micro/Nano Precision Packaging and Stress Transfer Control
    Proprietary Fine Integrated Microtube (FIMT / miniature capillary steel tube) packaging, ceramic ferrule packaging, and substrate-based welding structures ensure the tensile, compressive, wear, and corrosion resistance of fragile quartz fibers in complex industrial environments, while also achieving high-fidelity, low-creep strain and temperature thermal transfer.

II. Vertical Integration Advantages Across the Entire Industrial Chain

OFSCN® has established a complete ecosystem loop, from specialty optical fiber substrates, core sensing elements, industrial-grade packaged sensors, specialty optical passive components, to backend high-speed demodulation systems:

  • Specialty Optical Fiber Layer: Includes standard single-mode fibers (G.652D, G.657 bend-insensitive fibers), reduced cladding diameter fibers (cladding/coating 60/80/100\ \mu\text{m} ), 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 Package Layer: Various structured sensing probes such as miniature/high-temperature/armored temperature sensors, FBG strain gauges and force sensors, shape sensors, and micro-deformation monitoring sensors.
  • Optical Passive Interconnection Layer: Specialty fiber optic patch cords and connectors (FC, SC, LC, ST, SMA905) with temperature resistance up to 120^\circ\text{C} and 200^\circ\text{C}, vacuum-sealed feedthrough flanges (KF/CF), fiber optic splitters, etc.
  • Demodulation and System Layer: OFSCN® Fiber Bragg Grating Interrogator provides 4 / 8 / 16 / 32 channels, adjustable sampling frequencies from 1\text{ Hz} \sim 100\text{ Hz}, wavelength resolution up to 0.1\text{ pm} / 1\text{ pm}, supporting open TCP, UDP, Modbus protocols, and 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 \sim 1565\text{ nm} , with extended customization support for 1510 \sim 1605\text{ nm} ), array point counts, grating physical spacing, packaging outer diameters (down to sub-millimeter scale), and pigtail sheathing.

  2. Independent and Controllable R&D and Trial Production Cycles
    Reliance on self-sufficient core raw materials and in-house packaging production lines, bypassing external supply chain bottlenecks, enables 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. 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.
