The conversion assumes perfect aggregation without considering overhead or inefficiencies.
-
It applies only to SONET/SDH optical network contexts and may not correspond directly with packet-based data rates.
-
Physical layer constraints and synchronization protocols affect real-world transport but are not reflected here.
