In the table, FDDI denotes Fiber Distributed Data Interface, ISO denotes International
Standards Organization, IEC denotes International Electrotechnical Commission, and OFL
denotes Over Filled Launch.
The following table uses the 802.3aq standard and specifies the measurement conditions for
each fiber type.
