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 OC-768s are in an OTU3?
An OTU3 carries 1 OC-768, per ITU-T G.709. This is a client mapping of OC-768 into ODU3.
1
OC-768 in an OTU3
Working
OTU3 → 1 × ODU3 → 1 × OC-768
- 1 × ODU3 in each OTU3 ITU-T G.709The OTU3 frame carries exactly one ODU3.
- 1 × OC-768 in each ODU3 ITU-T G.709Client mappingCBR OC-768, the same client rate as STM-256, mapped into OPU3.
- 1 ODU3
- 1 × 1 = 1 OC-768
Leftover capacity
3.205293559 Gbit/s of each OTU3 line rate (43.018413559 Gbit/s) sits outside 1 × 39.813120 Gbit/s of OC-768 line rate (39.813120 Gbit/s). That remainder is overhead, fixed stuff or justification. It is not another whole tributary.
