Cladding Mode Free Photosensitive Single-Mode Fiber with Polyimide Coating
Nufern Cladding Mode Free (CMF) fiber is designed to allow more uniform grating writing in WDM applications. CMF virtually eliminates all cladding modes, allowing tighter channel spacing for high speed communications. Cladding Mode Free fiber is mode-matched to SMF-28™ for telecommunication system use. The polyimide coated CMF fiber (CMF-P) is ideally suited for use in WDM distributed sensing networks operating in high temperatures and harsh environments.
