The F-Tile Ethernet Hard IP supports OTN mode in all Ethernet modes with optional RS-FEC feature.
The TX
OTN
datapath
consists of:
- Alignment insertion—Alignment Marker and its position are made available for OTN based on the Ethernet mode of operation. Refer to Signals of the PCS66 TX Interface table for more information.
- Striper—enables logically sequential data to be segmented to increase data throughput.
Note: In OTN
mode in
10GE/20GE/40GE/50GE/100GE Ethernet modes, scrambler is bypassed because the
input data is expected to be
scrambled. In
200GE/400GE Ethernet modes, RS-FEC block descrambles the data.
The RX OTN datapath consists of an aligner block that enables the alignment of the incoming data.
