A fiber access communication system is developed to cater for the need of network communications industry. In this paper, the basic framework of the system is described; with regards to the characteristics of the system, firstly the electromagnetic interference approaches of the whole system are discussed. Emphasis is laid on the engineering analysis and discussion of the interference sources of electromagnetic emission, with solutions thereof suggested; meanwhile, analysis and discussion are conducted on the electromagnetic immunity of the system in view of electromagnetic coupling paths, with corresponding solutions put forward as well. Lastly, the EMC testing results of the system is presented. Practice has proven that this approach is specially favorable for EMC design and comprehension throughout the system development process, which is also effective for the communication industry in EMC design and verification.
