Description

To avoid errors of up to 800ns in media converters (e.g. 1 Gbit/s – 100 Mbit/s, SFPs), IEC/IEEE 61850-9-3 should specify that the Sync messages have to be padded to the same length as the Pdelay_Req and Pdelay_Resp messages. Media converters should be tested for asymmetry.
This will be stated in the revision of IEEE 1588, but IEC/IEEE 61850-9-3 refers to IEEE 1588:2008.
