Configurable safety shutdown for an optical amplifier using non-volatile storage

摘要

A system for configuring an optical amplifier in a fiber optic communications network including a safety shutdown input, includes a non-volatile memory for storing optical amplifier parameters. Circuitry is provided for inputting amplifier parameters into the memory and for changing previously stored amplifier parameters. Configuration of the optical amplifier parameters cannot be changed until a hardware control input is actuated. The system also provides for an indication of a mismatch between newly input parameters and previously stored optical amplifier parameters.
