Paper presents technology and some characteristic of manufactured suspended core microstructured optical fibers with cores undoped and doped with germanium dioxide. Manufactured fiber is very useful for evanescent wave sensors. Additionally on internal layers of holes thin (thickness about 28nm) silver layers were deposited. Those optical fibers probably will be very useful for surface plasmon resonance sensors. We introduced 6nm thick silver layers into holes of ordinary photonic crystal fibers 1m long.
