CMF-P, Cladding Mode Suppressed Photosensitive Optical Fiber

Product image of CMF-P, Cladding Mode Suppressed Photosensitive Optical Fiber

Coherent Cladding Mode Free (CMF-P) fiber is optimized for distributed WDM sensing networks operating in high-temperature and harsh environments. This fiber eliminates cladding modes, providing tighter channel spacing and superior performance for WDM applications.

Features and Benefits

  • Excellent cladding mode suppression - Allows for tighter channel spacing
  • Mode matched to conventional transmission fibers - Low splice loss
  • High-temperature coating - Enables distributed WDM sensing in harsh environments
  • RoHS compliant

Applications

  • Couplers
  • C+L band gratings
  • Polyimide version
  • Sensors
