[802SEC] Comments on 802.3ca and 802.3cb PARs and CSD
David
My comments on the PARs are as follows:
802.3ca
-General question: With wireless standards, we often specify a target
operating range. Is there a reason why a target distance is not
specified for NG EPON? It seems that the stakeholders would have
some expectation of the length of fiber over which this standard can
reliably deliver the advertised data rate. This distance should be
stated in the scope
802.3b
-General question: With wireless standards, we often specify a target
operating range. Is there a reason why a target distance is not
specified for this standard? It seems that the stakeholders would
have some expectation of the backplane distance or copper twinax
length over which this standard can reliably deliver the advertised
data rate. This distance should be stated in the scope.
CSD
Compatibility: This 5C states that "shall be compatible with 2.5 Gb/s
and 5 Gb/s MAC operation being defined in IEEE P802.3bz". If so, then
the PAR (5.3) should reflect that this standard depends on the
completion of IEEE P802.3bz.
