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 ODU1s are in an OTU3?
An OTU3 carries 16 ODU1s, per ITU-T G.709.
16
ODU1s in an OTU3
Working
OTU3 → 1 × ODU3 → 16 × ODU1
- 1 × ODU3 in each OTU3 ITU-T G.709The OTU3 frame carries exactly one ODU3.
- 16 × ODU1 in each ODU3 ITU-T G.70916 ODU1s, two slots each.
- 1 ODU3
- 1 × 16 = 16 ODU1s
Leftover capacity
3.038011543 Gbit/s of each OTU3 line rate (43.018413559 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.
By bit rate only
Dividing the line rates gives 17.21, which floors to 17 ODU1s by bit rate only. The standard mapping is 16. Use the mapping.
