Passive optical avionics network

Abstract

The present disclosure is directed to a passive optical avionics network system and method. A passive avionics network may comprise: (a) an optical line terminal (OLT); (b) at least one optical network unit (ONU); (c) a fiber optic bus operably coupling the OLT and the ONU; and (d) an avionics module operably coupled to the ONU. An integrated modular avionics (IMA) system may comprise: (a) a line-replaceable unit (LRU), the LRU comprising: (i) a processing unit; and (ii) an optical line terminal (OLT); (b) at least one optical network unit (ONU); (c) a fiber optic bus operably coupling the LRU and the ONU; and (d) an avionics module operably coupled to the ONU. A method for avionics network communication may comprise: (a) providing avionics data; (b) transmitting the avionics data via a fiber optic network; (c) receiving the avionics data; and (d) controlling functionality of an avionics module according to the avionics data.
