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 ODU2?
An ODU2 carries 4 ODU1s, per ITU-T G.709.
4
ODU1s in an ODU2
Working
ODU2 → 4 × ODU1
- 4 × ODU1 in each ODU2 ITU-T G.709Four ODU1s. Each ODU1 takes two of the eight 1.25 Gbit/s tributary slots.
- 4 ODU1s
Leftover capacity
42.17342 Mbit/s of each ODU2 line rate (10.037273924 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.
