The fibers feature a Germanium doped fused silica core with graded index core profile. They are designed to work at the optical wavelengths 850 nm and/or 1300 nm for data communication.

The metalized optical fiber is supplied with either 24 kt Gold or Aluminum coating. These types of coatings allow for termination of the fiber directly soldered 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 stringent test procedures in accordance with the Telecommunications Industry Association (TIA/EIA) and international Fiber Optic Test Procedures (FOTP). Specific custom tests to verify application requirements are available. Heracle is proud distributor of metallized optical fiber manufactured by Waveguide Technologies, Inc. New Jersey, USA.
