FIELD: information technologies.
SUBSTANCE: in the method a unit of optical channel data transfer is built according to number of time slots of a higher order optical channel payload unit (HO OPU), identified for a unit of lower order optical channel data unit (LO ODU); LO ODU is displayed into a payload area of ODTU with M-byte granularity; information of service load is encapsulated into a payload area of ODTU; and ODTU is multiplexed, produced by display of LO ODU and encapsulation of service load information, into HO OPU, to ensure highly efficient and universal mode to display LO ODU into HO OPU.
EFFECT: expansion of application field due to provision of display for various speeds of transfer of lower order optical channel data units.
