Graded-Index Multimode Fibers

Single Mode & Multimode Fibers

# #


iXblue offers graded-index multimode fibers with various core size and NA. Standard MMGI fibers have a Ge-doped core surrounded by a silica cladding, radiation resistant MMGI fibers are also available and have a Fluorinated core.

The doping composition of the core can also be tailored for optimized transmission in the UV.

Fibers with cladding diameter between 80 and 550 µm can be manufactured with various core size, NA and coating (acrylate, high-temperature acrylate or polyimide).
