How many STM-16s are in an ODU3?

An ODU3 carries 16 STM-16s, per ITU-T G.709 and ITU-T G.707. This path maps STM-256 into ODU3 as a client, then follows that client's tributaries.

STM-16s in an ODU3

Working

ODU3 → 1 × STM-256 → 16 × STM-16

  1. 1 × STM-256 in each ODU3 ITU-T G.709Client mappingCBR STM-256 mapped into OPU3.
  2. 16 × STM-16 in each STM-256 ITU-T G.70716 × STM-16.

Leftover capacity

506.098983 Mbit/s of each ODU3 line rate (40.319218983 Gbit/s) sits outside 16 × 2.488320 Gbit/s of STM-16 line rate (39.813120 Gbit/s). That remainder is overhead, fixed stuff or justification. It is not another whole tributary.
