ODU2s in an ODU3
Working
ODU3 → 4 × ODU2
- 4 × ODU2 in each ODU3 ITU-T G.709Four ODU2s fill the 32 tributary slots of 1.25 Gbit/s.
- 4 ODU2s
Leftover capacity
170.123287 Mbit/s of each ODU3 line rate (40.319218983 Gbit/s) sits outside 4 × 10.037273924 Gbit/s of ODU2 line rate (40.149095696 Gbit/s). That remainder is overhead, fixed stuff or justification. It is not another whole tributary.
