We report a field demonstration of the differential-phase-shift quantum key distribution (DPS-QKD) system over 90-km installed fiber under the framework of Tokyo QKD Network. We employed a 1-GHz clocked DPS-QKD system including stable planar lightwave circuit based Mach-Zehnder interferometer, high speed signal generator and its storage realized by field programmable gate array (FPGA), and high performance superconducting single photon detectors (SSPD) with an optical cavity. Ultra stable operation for more than eight days was successfully demonstrated under the field condition.
