The performance of a fiber array detection unit in a large area fiber array detector is tested. The transmission efficiency, time resolution and position resolution of the optical fiber detection unit with different shapes and different materials as well as the light guide wrapped with different reflective materials were tested. The material and shape of the light guide used in the detection unit of the large-area optical fiber detector are confirmed, and the time resolution achievable by the detection unit of the optical fiber array detector is given.
