Object
Set type of FEC.
g709 - 1st generation FEC according to
ITU-T G.709 (near 6 dB coding gain).
g9751I4 - FEC according to G975.1 I.4. Outer code: RS(1023,1007),
Inner code: BCH(2047,1952).
g9751I7 - FEC according to G975.1 I.7. Two orthogonally
concatenated BCH codes.
sdFec - Proprietary Soft Decision FEC scheme.
