Abstract

An optical transmission system includes a first amplifier that tilts optical signals in a first direction, an optical loss element, over which the optical signals are transmitted, and a second amplifier that tilts the optical signals in a second direction. The first amplifier tilts the optical signals in the first direction in response to an increase in an amount of power associated with the optical signals. The second amplifier tilts the optical signals in the second direction in response to a decrease in an amount of power associated with the optical signals.
