Abstract
Automatic optical link calibration systems and methods include, in an optical section with an Optical Add-Drop Multiplexer (OADM) multiplexer, an OADM demultiplexer, and zero or more in-line optical amplifiers between the OADM multiplexer and the OADM demultiplexer, wherein the optical section includes integrated measurement equipment, and wherein the OADM multiplexer and the OADM demultiplexer have a route and select architecture, obtaining measurement data from the integrated measurement equipment subsequent to turn up; determining an optimal target launch power profile per fiber span in the optical section based on the measurement data; configuring channel holders at the OADM multiplexer to meet the optimal target launch power profile per fiber span; and calibrating each fiber span to determine settings of equipment at the OADM multiplexer, the OADM demultiplexer, and the zero or more in-line optical amplifiers.
