Abstract
Disclosed is a temperature and strain sensing optical fiber including a first doped radial zone (Z) with an associated first Brillouin shift (BS) caused by the doping of said zone (Z) and a second doped radial zone (Z) with associated second Brillouin shift (BS) caused by the doping of said second zone (Z). The concentration and/or composition of the doping materials in said first and second radial zones are chosen such that the first Brillouin Shift (BS) is different from the second Brillouin Shift (BS) for all variations of said Brillouin Shifts (BS, BS) caused by temperature and/or strain.
