Step Index Multimode Fibers Metal Coated Series: Aluminum

Step Index Multimode Fibers Metal Coated Series: Aluminum

Pure fused silica step index multimode fibers (SIMM), optimised for applications in the UV/VIS and VIS/IR wavelengths.

The fiber is protected with a 99.99 % Aluminum coating. Aluminum coatings not only enable the fiber to be used in applications of a wider temperature range, but also offers excellent protection at extended stress levels. As an electric conductor this type of coating provides the user with the ability to terminate the fiber directly onto the coating, supporting a hermetically sealed assembly. The manufacturing process utilized in the production of these fibers results in a superior strength optical fiber, with improved long term reliability especially under extreme bend radius applications. Unlike polymers, metal coatings such as Aluminum have very low outgassing of volatile components.

All Aluminum coated 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). Custom specific tests to verify application requirements are available. 


Aluminum coated step index multimode 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

  • Semiconductor manufacturing


  • Wide operating temperature range (from cryogenic up to 400° C)
  • Hermetic & sterilizable
  • Directly solderable for vacuum feedthroughs & laser diode pigtailing
  • Radiation resistant
  • Low outgassing
  • Resistant to organic solvents
