Copied verbatim from their website....
iDirect’s 2D 16-State FEC coding is a next-generation, extremely efficient inbound coding that provides maximum flexibility to satellite network designs. The FEC coding ranges from 1/2 to 6/7 and are available in three new IP payload block sizes, enabling more granularity and block size choices than turbo product codes or LDPC, which can lead to typical link margin improvements of 1dB.
Easy mapping between existing TPC to 2D 16-State configuration makes implementation quick and simple, as no new network design is required. And it provides existing customers a 10-20% increase in their inbound IP throughput without sacrificing link performance. It also provides greater flexibility in network design with a more granular selection of block sizes and code rates. This FEC coding is available on Evolution® routers and line cards when using DVB-S2 on the outbound.
