HERACLE GMBH - Customized specialty optical fiber solutions

Our gold coated fiber is available for both wavelength ranges: from UV, VIS up to infrared wavelength ranges. The fiber offers excellent protection against chemical corrosion & mechanical stres and is capable of withstanding extreme temperatures and harsh environments. The fiber can be terminated directly onto the coating for hermetically sealed assembly. Our Gold coated fiber has very low outgassing of volatile components. We perform 100% stringend test procedures according to international standards. Typical applications are typically for extreme conditions such as: • Aircraft, missile, rocket, turbine & jet engine monitoring • Radiation, caustic & corrosive environments • Material fatigue sensing applications • High power laser delivery systems • Ultra high vacuum applications

Our aluminum coated fiber are available for both operating windows in ultraviolett and visible/near infrared wavelength ranges. In addition, heracle offers a solarisation resistant version for ultraviolett region. The fiber features a wide operating temperature range from cryogenic up to 400° C and makes it ideal for Aircraft, missile, rocket, turbine & jet engine monitoring. The aluminum layer offers a hermetic coating. The fiber can be sterialized. Termination can be directly soldered for vacuum feedthroughs & laser diode pigtailing. Its radiation resistancy, low outgassing and resistancy to organic solvents allow for operation in radiation, caustic & corrosive environments.

heracle offers germanium doped fused silica graded index multimode fibers needed for data communication at the optical wavelengths 850 nm and/or 1300 nm. The metalized optical fiber is supplied with either 24 kt Gold or Aluminum coatings. As an electric conductor, these types of coatings provide the user with the ability to terminate the fiber directly onto the coating, supporting hermetically sealed assemblies. Gold and Aluminum coated fibers are capable of withstanding extreme temperatures and harsh environments. The manufacturing process utilized in the production of these fibers result in low stress corrosion susceptibility, and thus offering improved mechanical protection to the optical fiber when used in the most challenging harsh environments. All metal coated graded index fibers are 100 % quality tested to Heracle‘s stringent test procedures in accordance with the Telecommunications Industry Association (TIA/EIA) and international Fiber Optic Test Procedures (FOTP).

The featured Singlemode (SM 9/125) metal coated fiber operates in both, 1310 nm and 1550 nm wavelength ranges, according to G.652 A/B standards. The fiber is supplied with either 24 kt Gold or Aluminum coatings. As an electric conductor, these types of coatings provide the user with the ability to terminate the fiber directly to the coating, supporting hermetically sealed assemblies. Gold and Aluminum coated fibers are most capable of withstanding high temperatures and harsh environments compared to conventional coated fibers. The fibers have low stress corrosion susceptibility and offer superior mechanical protection in the most challenging harsh environments. All metal coated Singlemode fibers are 100 % quality tested to Heracle‘s stringent test procedures in accordance TIA/EIA and international Fiber Optic Test Procedures (FOTP). Custom specific tests to verify application requirements are available.

heracle developes and produces specialty optical fiber with metal coating for application in harsh environments. Fiber types include Mutimode fiber with step or graded index profiles and Singlemode fiber. All fiber fiber types can be offered with either Gold or Aluminum coating. The pure fused silica step index multimode fibers (SIMM) are optimised for applications in the UV/VIS and VIS/IR wavelengths. The graded index Multimode fiber is designed to operate at 850nm and 1300nm. The Singlemode fiber is specified accoring to according ITU-T G.652. Metal coated optical fibers are typically used under extreme conditions such as: - Aircraft, missile, rocket, turbine & jet engine monitoring; - Radiation, caustic & corrosive environments - Material fatigue sensing applications - High power laser delivery systems - Ultra high vacuum applications
