GEPON Optical Line Termination

                                                             ----up to 8 PON port,4 GE uplink




4PON port Module card
ZISA’s ZS-OLT1508 GEPON system (Optical Line Termination, OLT) is located in the operator's central office and different types of ONU (Optical Network Unit, ONU) are located at customer premises for FTTB/H connections. The ZS-OLT1508 is connected by a single fiber to an optical power splitter that supplies the optical signal to as many as 256 sets of ONUs (each OLT PON port supports up to 32 ONU sets). Or as many as 512 sets of ONUs(each OLT PON port supports up to 64 ONU sets,need enable FEC function)The ZS-OLT1508 is a mini 1U chassis with a Layer-2 GEPON switch featuring 8 GEPON ports (2 PON modules), 4 Gigabit uplink ports (4 copper and 4 SFP combo ports) and one 10/100Mbps Ethernet port for out-of-band management. For CPE compatibility, ZISA provides several models for different network architecture needs.
