Abstract
A communication node is configured to automatically select an optimum common operational mode between itself and a link partner. The communication node sends advertisement packets across a fiber optic medium in order to broadcast its operational capabilities to the link partner. These operational capabilities may include 10BASE-FL and 100BASE-FL. Transitions may be inserted between the advertisement packets which may include clock pulses, data pulses and transitions. The communication node may be attached to a network having a bus architecture and may further be configured to identify an idle signal.
