I.4Redundancyratio Abstract
Deals mainly with the implementing of a Forward Error Correction (FEC) function in the multigigabit-per-second optical fibre submarine cable systems. The applications are both optically amplified repeatered systems and repeaterless optical systems (as shown in Rec. G.973). This function is not compulsory.
