This part of ISO/IEC 9314 specifies a series of tests in order to verify conformance of FDDI stations to the requirements of ISO/IEC 9314-3:1990.

NOTE ISO/IEC 9314-3 specifies the requirements for the optical input/output port of FDDI stations as well as for cable plants. It states that a bit error rate for a station-to-station link should not exceed 2,5 × 10?10 for conforming stations connected to each other through a conforming cable plant.
