Energy-time entangled photon-pairs at telecom band are generated via spon- taneous four wave mixing (SFWM) process in optical fibers under continuous wave (CW) pumping. A time domain filter is used to suppress the impact of noise photons and improve the noise property. The characterization of energy-time entanglement is presented through an experiment of Franson-type interference and a violation of CHSH-Bell inequality. It shows that the SFWM in optical fibers under CW pumping provides a simple and practical way to generate high-quality energy-time entangled photon-pairs at telecom band.
