Abstract: According to an example, a transmitter transmits a plurality of optical signals of multiple wavelengths via an optical link to a receiver. An optical link tuner coupled to the optical link groups the plurality of optical signals into a first group of optical signals and a second group of optical signals, where the first group of optical signals has a first wavelength range and the second group of optical signals has a second wavelength range. The optical link tuner adjusts link tuning parameters associated with the first group of optical signals during a first phase, such that the second group of optical signals is propagated to the receiver without modifications to link tuning parameters associated with the second group, where during the first phase the receiver is to detect unplugging of the optical link based on the second group of optical signals.

Abstract: Examples described herein relate to a receiver training method. To configure a static gain for at least one static gain amplifier and a target amplitude for a dynamic gain amplifier, a dynamic gain adjustment is disabled and the dynamic gain amplifier is configured to apply a predetermined fixed gain to the static gain amplified signal to generate a test signal. Furthermore, an effective static gain magnitude for at least one static gain amplifier and an effective amplitude for the test signal are determined based on a link performance metric. The static gain is set to the effective static gain magnitude, and a target amplitude for the dynamic gain amplifier is set to the effective amplitude. Then, the dynamic gain adjustment may be enabled to maintain an amplitude of a dynamic gain amplified signal at an output of the dynamic gain amplifier at the target amplitude by varying the dynamic gain.
