I don't believe copper cable redundancy is part of the Profibus specification. You can have cable redundancy using fibre-optic cabling but for virtually all Profibus master and slaves you will still need a small copper-to-fibre-optic adapter or converter. Very few (if any) devices offer direct fibre-optic connection to the bus.
