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 OTU2?
An OTU2 carries 4 ODU1s, per ITU-T G.709.
4
ODU1s in an OTU2
Working
OTU2 → 1 × ODU2 → 4 × ODU1
- 1 × ODU2 in each OTU2 ITU-T G.709The OTU2 frame carries exactly one ODU2.
- 4 × ODU1 in each ODU2 ITU-T G.709Four ODU1s. Each ODU1 takes two of the eight 1.25 Gbit/s tributary slots.
- 1 ODU2
- 1 × 4 = 4 ODU1s
Leftover capacity
714.124812 Mbit/s of each OTU2 line rate (10.709225316 Gbit/s) sits outside 4 × 2.498775126 Gbit/s of ODU1 line rate (9.995100504 Gbit/s). That remainder is overhead, fixed stuff or justification. It is not another whole tributary.
