How many ODU0s are in an OTU2?
An OTU2 carries 8 ODU0s, per ITU-T G.709.
8
ODU0s in an OTU2
Working
OTU2 → 1 × ODU2 → 8 × ODU0
- 1 × ODU2 in each OTU2 ITU-T G.709The OTU2 frame carries exactly one ODU2.
- 8 × ODU0 in each ODU2 ITU-T G.709Eight ODU0s, one per 1.25 Gbit/s tributary slot.
- 1 ODU2
- 1 × 8 = 8 ODU0s
Leftover capacity
755.945316 Mbit/s of each OTU2 line rate (10.709225316 Gbit/s) sits outside 8 × 1.244160 Gbit/s of ODU0 line rate (9.953280 Gbit/s). That remainder is overhead, fixed stuff or justification. It is not another whole tributary.
