The gaming devices display the primary game outcomes and provide the players with any awards associated with the primary game outcomes. Additional aspects described herein facilitate quantized feedback scheduling, wherein scheduling is performed based on signal quality feedback that is quantized into a finite number of bits by respective users. The output electrical signal has a substantially lower frequency than the input optical signal channels and the output optical signal channels.
