COVF Specialty Optical Fibers

COVF Specialty Optical Fibers

COPL’s optical fiber fabrication research teams have developed an unparalleled know-how: from glass design, to MCVD preform synthesis, to the drawing of specialty optical fibers. Discover our infrastructure and the different types of optical fibers drawn in our facilities. Fiber compositions, geometries and guiding properties can be customized to fit your needs and applications.

Contact us to discuss the feasibility of your project:


MCVD process

  • Silica preform synthesis
  • Vapour phase deposition
  • Doping (Ge, P, Al) for index control
  • Doping (Er, Yv, Nd, Th, etc. for active fibers

Silica fiber drawing tower

  • For silica fibers

Drawing tower – Other materials

  • 4 furnaces covering a wide range of transition temperatures
  • For polymers, chalcogenides, tellurites, phosphates, silicophosphates, etc.
