We generate 1550 nm correlated photon pairs
through the spontaneous four-wave mixing (SpFWM) process
in a highly nonlinear fiber (HNLF). The pair source quality
generation is evaluated by the coincidence-to-accidental ratio
(CAR) parameter. It is verified that the spontaneous Raman
scattering (SpRS) photons generated inside the fiber contribute
to the degradation of the source. Nevertheless, a CAR value of
2.77 is found for a pump power at the input of the fiber of
