Low-noise single-photon detection at 1550 nm was demonstrated using an indium–gallium–arsenide avalanche photodiode cooled to 130 K. Discharge pulse counting was adopted for after-pulse-suppressed single-photon detection. The dark-count probability and after-pulse probability were $1.4\times 10^{-7}$ and $6.3\times 10^{-4}$, respectively, when the quantum efficiency was 10%. The repetition frequency of single-photon detection was 100 kHz.
