A method of managing gain tilt in an optical transmission segment
including providing an optical transmission segment having a plurality of
fiber optic cable spans and a plurality of repeaters coupled to the fiber
optic cable spans. Gain tilt in the optical transmission segment is
monitored. If negative gain tilt is accumulated at a repeater location in
the transmission segment, the repeater at the repeater location is
replaced with a higher gain repeater having a higher nominal gain value
than the nominal gain value of the repeater being replaced.
