The invention discloses an FTTH network management server. According to the FTTH network management server, an FTTH network comprises first grade virtual splitters, first grade solid splitters, second grade virtual splitters and second grade solid splitters, wherein an output port of each first grade solid splitter is connected with an input port of one second grade solid splitter, an output port of each first grade virtual splitter is connected with an input port of one second grade virtual splitter, splitter information of each splitter and connection information between splitter ports are stored in a management server and are for management on the FTTH network, and the splitter information comprises identification information used for identifying the virtual splitters or the solid splitters, location positions of the splitters and splitting ratios of the splitters. The invention further discloses a corresponding dynamic fiber jumping method. Through the FTTH network management server and the method, a resource utilization rate of a resource port is improved, idle waste of equipment resources can be reduced, and long-term network programming is convenient.
