The ultimate goal of quantum information science is to build a global quantumnetwork, which enables quantum resources to be distributed and shared betweenremote parties. Such quantum network can be realized by all fiber elements,which takes advantage of low transmission loss,low cost, scalable and mutualfiber communication techniques such as dense wavelength division multiplexing.Therefore high quality entangled photon sources based on fibers are ondemanding for building up such kind of quantum network. Here we reportmultiplexed polarization and timebin entanglement photon sources based ondispersion shifted fiber operating at room temperature. High qualities ofentanglement are characterized by using interference, Bell inequality andquantum state tomography. Simultaneous presence of entanglements inmultichannel pairs of a 100GHz DWDM shows the great capacity for entanglementsdistribution over multi-users. Our research provides a versatile platform andmoves a first step toward constructing an all fiber quantum network.
