Abstract
A system for passive optical network (PON) communication includes an optical network terminal comprising one or more memories configured to store routing policy information, and processing circuitry coupled to the one or more memories and configured to: receive a set of information from a subscriber device; determine a priority level of the set of information based on the routing policy information; select a first PON protocol from a plurality of PON protocols based on the priority level of the set of information for transmission of the set of information; and cause transmission of the set of information on a fiber optical link in accordance with the first PON protocol.
