Abstract:
1. A method of initiating forward error correction in an ethernet passive optical network including at least one optical network unit, comprising the steps of: by an optical line terminal: (a) upon receiving forward error corrected data from the at least one optical network unit, responding thereafter with forward error corrected data; and (b) upon receiving data not forward error corrected from the at least one optical network unit, responding thereafter with data not forward error corrected; wherein the step of responding thereafter with forward error corrected data includes changing a transmission protocol and state to send forward error corrected protected frames to the at least one optical network unit; and wherein the step of responding thereafter with data not forward error corrected includes changing a transmission protocol and state to send data not forward error corrected protected frames to the at least one optical network unit.
