Abstract
A method of parallelized optical link calibration of an optical section having a plurality of spans interconnecting a transmit Optical Add/Drop Multiplexer (OADM) with a receive OADM via a plurality of line amplifiers includes partitioning the optical section into a plurality of sub-sections, each including one or more spans of the plurality of spans; utilizing equipment at the plurality of line amplifiers to isolate the plurality of sub-sections from one another; and performing measurements of spans for the parallelized optical link calibration in some or all of the plurality of sub-sections at a same time. Advantageously, timing of the parallelized optical link calibration is independent of a number of spans in the optical section.
