Domestic Fiber Bragg Gratings typically range from $45 to $100 per unit, with additional costs for chirped, PM, or high-temperature variants.

Standard Inventory FBGs

Uniform FBGs for common wavelengths such as 1550 nm, 1310 nm, and 1060 nm are available at $45 per piece for 1550 nm and 1310 nm, and $50 per piece for 1060 nm, with a minimum order of 10 units . These prices apply to bare fiber gratings without additional packaging.

Specialized Configurations

• Chirped FBGs: Add approximately $20 per unit to the base price .
• Polarization-Maintaining (PM) FBGs: Add approximately $25 per unit .
• High-Temperature or Packaged Sensors: FBGs designed for extreme environments (up to 800°C) or with protective housings are more expensive due to specialized coatings and packaging .

Sensor Applications

FBGs used as temperature, strain, pressure, displacement, or acceleration sensors vary in price depending on packaging and measurement range. Bare fiber sensors are the most economical, while packaged sensors with protective housings command higher prices but offer durability and easier installation . Multi-point sensor arrays reduce per-sensor cost when deploying 8, 16, or 32 sensors on a single fiber .

Summary

For domestic procurement, expect:

• Basic bare FBGs: $45–$50 per unit
• Chirped or PM FBGs: $65–$75 per unit
• Packaged or high-temperature FBG sensors: $80–$100+ per unit depending on specifications and environmental requirements . These prices provide a practical reference for budgeting and selecting FBGs for optical communication, sensing, or laser applications.
