¿µ¹®³»¿ë¿ä¾à The standard specifies optical transport network structure, client signal mapping types,multiplexing and demultiplexing method to transport the various client signals over the optical transport network. This standard defines bit-rate, frame structures and overhead structures of OTUk/ODUk/OPUk signals and FEC types. To support OTN
B100G, edition 5.0 of this standard includes addition of beyond 100 Gbit/s OTU, ODU and OPU frame formats, overhead, ODU multiplexing, client mappings and optical layer terminology updates. Edition 5.0 furthermore deleted the OPUk concatenation specifications and the ATM mapping into OPUk specification and changed the TCM
ACT and FTFL overhead bytes into EXP overhead bytes.
