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 OTU1?
An OTU1 carries 1 ODU1, per ITU-T G.709.
1
ODU1 in an OTU1
Working
OTU1 → 1 × ODU1
- 1 × ODU1 in each OTU1 ITU-T G.709The OTU1 frame carries exactly one ODU1. The line-rate gap is OTU overhead and FEC.
- 1 ODU1
Leftover capacity
167.282017 Mbit/s of each OTU1 line rate (2.666057143 Gbit/s) sits outside 1 × 2.498775126 Gbit/s of ODU1 line rate (2.498775126 Gbit/s). That remainder is overhead, fixed stuff or justification. It is not another whole tributary.
