Quantity is how many containers you have. The result is how many tributaries fit, the path, and the leftover line rate. The choices stay in the URL, so you can share them.

How many ODU0s are in an OTU3?
An OTU3 carries 32 ODU0s, per ITU-T G.709.
32
ODU0s in an OTU3
Working
OTU3 → 1 × ODU3 → 32 × ODU0
- 1 × ODU3 in each OTU3 ITU-T G.709The OTU3 frame carries exactly one ODU3.
- 32 × ODU0 in each ODU3 ITU-T G.70932 ODU0s, one slot each.
- 1 ODU3
- 1 × 32 = 32 ODU0s
Leftover capacity
3.205293559 Gbit/s of each OTU3 line rate (43.018413559 Gbit/s) sits outside 32 × 1.244160 Gbit/s of ODU0 line rate (39.813120 Gbit/s). That remainder is overhead, fixed stuff or justification. It is not another whole tributary.
By bit rate only
Dividing the line rates gives 34.57, which floors to 34 ODU0s by bit rate only. The standard mapping is 32. Use the mapping.
