Abstract
A method for optical transmission of high speed data and an optical receiver for receiving such high speed data is provided. The method includes transmitting an optical signal having a first logic-high and first logic-low defining a first modulation amplitude that is sub-band modulated with a toggling signal having a first toggling amplitude with a first modulation index, receiving the optical signal with an optical receiver circuit and converting the optical signal to an intermediate electrical signal, IES, having: a second logic-high and a second logic-low defining a second modulation amplitude, and a second toggling amplitude having a second modulation index, providing a decision threshold relative to the IES as a function of the second modulation amplitude, and adjusting the threshold by determining the second toggling amplitude and adjusting the threshold relative to the IES based on proportionality between the second toggling amplitude and the second modulation amplitude.z.
