Abstract
Disclosed are an online program update method and device for an optical amplifier. The method comprises: when a program update instruction is sent, a Microcontroller Unit MCU receiving update programs of MCU and a programmable logic device FPGA, storing them in a program memory device, and sending an update instruction to FPGA; FPGA terminating; operations of a digital-to-analog converter DAC according to the instruction and a current state remaining unchanged; MCU loading new codes of MCU and FPGA while DAC remains in state of halting refreshing; and after MCU and FPGA run the new codes, reading previously stored data, and starting switching from a previous operation state to enter normal operation state. On basis of conventional optical amplifier control, the invention combines characteristics of MCU and FPGA, and ensures uninterrupted service of optical amplifiers, achieving smooth transition of services, thereby improving stability and reliability of whole optical communications systems.
