multicore optical fiber

Based on our original telecom experience of making Twincore fibers for the Add/drop mutiplexers, iXblue in collaboration with Photonics Bretagne is now offering Multicore fibers for shape and temperature/strain sensing.
Multicore fibers can be used in a large variety of sensing application where the need to reduce the global footprint is also required for cables and connectors.
Multicore fibers have photosensitive cores, allowing Fiber Bragg Grating (FBG) inscription and can be tailored to match the exact customer specifications.
