I have reviewed this change made in the merge of 802.3bv into Std 802.3. In my opinion, the change is correct and I expected it.
This topic was addressed during 802.3bv TF meeting in Macau, last year, if I remember well. The clause 115 does a reference
to the IEC 60793-1-41:2010 norm for the measurement methodology of the fiber optic channel transfer function. However, none of the
launching conditions described in the IEC 60793-1-41:2010 norm are used for transfer function measurement. IEEE Std 802.3bv specifies
the launching condition (MPD) based on EAF per IEC 61300-3-53.
On the other hand, the clause 52 provides a reference to the same norm IEC 60793-1-41 for the specification of the overfilled launch
The 802.3bv TF reviewed both IEC 60793-1-41:2001 and IEC 60793-1-41:2010 in Macau meeting, and we concluded that the specification
of the measurement method for transfer function is much more clear and exact in the 2010 edition. This was the reason why the TF included
in subclause 1.3 the normative reference to IEC 60793-1-41:2010 despite the 2001 edition was already included in Std 802.3.
