12.3.2. OTN Mode

The GTS Ethernet Hard IP supports OTN mode in all Ethernet modes with optional FEC feature. The TX OTN datapath consists of:

  • Alignment insertion—the TX PCS interface inserts alignment markers.
  • Striper—enables logically sequential data to be segmented to increase data throughput.
Note: In OTN mode in 10GE Ethernet modes, scrambler is bypassed because the input data is expected to be scrambled The RX OTN datapath consists of an aligner block that enables the alignment of the incoming data.
