Few-mode Fibre (FMF)

YOFC FMFs take advantages of PCVD process which is able to manufacture complex index-profile accurately and optical waveguide structure flexibility to get various types of core layer structure, such like Step-Index, Graded-Index etc.
Applications

•     Mode division multiplexing(MDM)
•     Communication
•     Sensing
•     Test

Characteristics

•     Strictly controlled optical and geometrical parameters
•     Customized waveguide is available
