WebTFI-5: TDM Fabric to Framer Interface Implementation Agreement - OIF WebA frame format is defined by which data packets are encapsulated, in a way that is similar to that of a SONET frame. The above format creates a transparent, hierarchical network combining TDM and WDM switching functions. OPU: Optical Channel Payload Unit. This contains the encapsulated client data and a header describing the type of that data.
WebThe PN-1 1 sequence fills the entire OTUk frame. Figure 8 shows an OTUk frame and the extent of the PN-11 sequence. The OTUk frame is carried as an OTM-0.k signal connecting the DWDM equipment 10 to the ODUk cross-connect 20.
