Polymer or metal coated step index multi mode fibers

The SFS and AFS fibers are primarily used in photonics applications where individual or bundled large core (>50µm) multimode fibers are needed for the transmission of optical energy. These fibers can be coated with a variety of polymers or metalized, for extreme temperature performance.
