¿µ¹®³»¿ë¿ä¾à | This standard addresses the general characteristics of gigabit-capable passive optical network (GPON) systems in order to guide and motivate the physical layer and the transmission convergence layer specifications. The general characteristics include examples of services, user-network interfaces (UNIs) and service node interfaces (SNIs) that are requested by network operators. Also, this standard shows the principle deployment configuration. GPON systems are characterized, in general, by an optical line termination (OLT) system and an optical network unit (ONU) or optical network termination (ONT) with a passive optical distribution network (ODN) interconnecting them. There is, in general, a one-to-many relationship between the OLT and the ONU/ONTs, respectively. And also, it includes text describing the operation of GPON with IEEE 1588; use cases for GPON frequency and time of day synchronization; and the transport of ESMC messages over PON. | ||
