Abstract: A software-defined (SD) optical network is disclosed. An SD optical line terminal (OLT) includes a global SD controller, one or more SD OLT drivers connected to the global SD controller, and an underlying hardware component connected to each of said one or more SD OLT drivers. An SD optical network unit (ONU) includes a local SD controller, one or more SD optical network unit (ONU) drivers connected to the local SD controller, and an underlying hardware component connected to each of said one or more SD ONU drivers, wherein the local SD controller manages said one or more SD ONU drivers by issuing commands communicated to said one or more SD ONU drivers, and wherein each of said one or more SD ONU drivers implements a required function on the underlying hardware component. Other apparatuses, systems, and methods also are disclosed.

Abstract: A method for optimal combined 2R/3R regenerators placement for optical transmission includes determining an optimal placement of multiple 2R and 3R regenerators that minimizes bit error rate BER at a destination node, determining an optimal number of the 2R and 3R regenerators that minimizes a total cost while satisfying the BER at the destination node, and determining an optimal placement of the 2R and 3R regenerators along a route in the optical transmission.
