NOVELTY - The utility model claims one based on optical fibre temperature sensor's graphene, wherein the upper section circular one common optical fibre, wherein one section of cladding's area's 1 to 3 cm sensing optical fibre, an optical fibre sensing area is removed, the shortest distance's optical fibre and core interface is 1 to 3, depositing the reduction-oxidation graphene film, reducing the thickness of the graphene oxide film's is 10 to 30 (mu) m upper optical fibre sensing area. The utility model uses the graphite alkene's hot to light absorbing effect making temperature sensor, has fast response speed, high sensitivity, long service life, strong anti-electromagnetic interference capability and so on.
