Abstract
A distributed fiber optic communication network for controlling a gas turbine engine includes a computation module and an input/output (I/O) module. The computation module and the I/O module are connected via the communication network. The communication network comprises multi-mode fiber optic cables, wherein data is transferred thereon on multiple frequency bands. The frequency bands range from about 300 nm to about 1550 nm. A method of frequency hopping is provided in which communication band instructions are stored locally on nodes of the communication network and may include communication band instructions transmitted to nodes of the communication network on a dedicated band.
