  Single photon sources operating on-demand at telecom wavelengths are required
in fiber-based quantum secure communication technologies. In this work we
demonstrate single photon emission from position-controlled nanowire quantum
dots emitting at {\lambda} > 1530 nm. Using above-band pulsed excitation, we
obtain single photon purities of g(2)(0) = 0.062. These results represent an
important step towards the scalable manufacture of high efficiency, high rate
single photon emitters in the telecom C-band.
