We report a bright and tunable source of spectrally pure heralded singlephotons in the telecom O-Band, based on cross-polarized four wave mixing in acommercial birefringent optical fiber. The source can achieve a purity of 85%,heralding efficiency of 30% and high coincidences to accidentals ratio of 108.Furthermore, the possibility of building multiple identical sources isexplored. Through the measurements of joint spectral intensities, we find thatthe fiber is homogeneous over atleast 45 centimeters and can potentiallyrealize 4 identical sources. This paves the way for a cost-effectivefiber-optic approach to implement multi-photon quantum optics experiments.
