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.
