How many ODU1s are in an OTU1?
An OTU1 carries 1 ODU1, per ITU-T G.709.

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.
