An ODU3 carries 16 ODU1s, per ITU-T G.709.
16
ODU1s in an ODU3
Working
ODU3 → 16 × ODU1
- 16 × ODU1 in each ODU3 ITU-T G.70916 ODU1s, two slots each.
- 16 ODU1s
Leftover capacity
338.816967 Mbit/s of each ODU3 line rate (40.319218983 Gbit/s) sits outside 16 × 2.498775126 Gbit/s of ODU1 line rate (39.980402016 Gbit/s). That remainder is overhead, fixed stuff or justification. It is not another whole tributary.
