How many STM-64s are in an ODU2?
An ODU2 carries 1 STM-64, per ITU-T G.709. This is a client mapping of STM-64 into ODU2.

Working
ODU2 → 1 × STM-64
- 1 × STM-64 in each ODU2 ITU-T G.709Client mappingCBR STM-64 mapped into OPU2.
- 1 STM-64
Leftover capacity
83.993924 Mbit/s of each ODU2 line rate (10.037273924 Gbit/s) sits outside 1 × 9.953280 Gbit/s of STM-64 line rate (9.953280 Gbit/s). That remainder is overhead, fixed stuff or justification. It is not another whole tributary.
