ODU3s in an ODU4

Working

ODU4 → 2 × ODU3

  1. 2 × ODU3 in each ODU4 ITU-T G.709Each ODU3 takes 31 of the 80 ODU4 tributary slots, so 2 fit and 18 slots stay unused.

Leftover capacity

24.156007849 Gbit/s of each ODU4 line rate (104.794445815 Gbit/s) sits outside 2 × 40.319218983 Gbit/s of ODU3 line rate (80.638437966 Gbit/s). That remainder is overhead, fixed stuff or justification. It is not another whole tributary.
