Abstract: In order to meet the demand for increasing types of railway GPON system bearer services, combined with the high bandwidth, high reliability and high safety requirements of railway access network, this paper mainly introduces the protection mechanisms of GPON system and puts forward suggestions on the applicable scenarios of various protection schemes. Focusing on the actual situation of Beijing-Guangzhou railway service carrying, the application of different protection mechanisms in different scenarios is studied, so as to improve the safety and reliability of railway GPON systems under the premise of saving construction costs.


Key words: GPON, protection mechanism, reliability
