High Temperature Resistant Pigtail Fiber Ordering

High-temperature resistant fiber optic pigtails can be ordered using fused silica or sapphire fibers with heat-resistant coatings, supporting temperatures from −190 °C up to over 2,000 °C depending on the material.

Fiber Material Options

• Fused Silica Fibers: These fibers can be equipped with heat-resistant coatings to operate in a temperature range from −190 °C to +385 °C, making them suitable for most high-temperature industrial applications (WEINERT Industries) .
• Sapphire Fibers: Single-crystal sapphire fibers are extremely heat-resistant, with a melting point of 2,072 °C, and are chemically and scratch resistant. They are ideal for extreme high-temperature sensing or harsh chemical environments. Sapphire fibers are available in diameters from 60 µm to 500 µm and can be supplied as pigtails with protective jackets and connectors on demand (IDIL Fiber Optics) .

Pigtail Configurations

• Standard Pigtails: Short fiber cuts with connectors on one end, used for splicing in Optical Distribution Frames, termination boxes, or enclosures. Available in singlemode (G657A1/A2) and multimode (OM1–OM5) fibers (Hexatronic) .
• Custom High-Temperature Pigtails: Suppliers can provide single-crystal fibers with end shaping, protective jackets, and connectors tailored to your project requirements, including high flexibility and chemical durability (IDIL Fiber Optics) .

Ordering Considerations

1. Temperature Range: Select fiber material and coating based on the maximum operating temperature. Fused silica is suitable up to ~385 °C, while sapphire fibers handle extreme temperatures above 2,000 °C.
2. Fiber Diameter: Smaller diameters increase flexibility; for example, a 100 µm fiber is significantly more flexible than a 200 µm fiber.
3. Connector Type: Specify the connector type required for your application; most suppliers offer standard and custom connectors.
4. Length Limitations: Sapphire fibers typically have a maximum length of 2 meters due to polishing and handling constraints.
5. Protective Coatings: Ensure the fiber has a heat-resistant coating compatible with your environment, especially for chemical or abrasive conditions.

Recommended Suppliers
