GEPON - Gigabit Ethernet Passive Optic Networks

Gigabit Ethernet Passive Optic Network is a telecommunications network that uses point to multipoint fiber to the premises in which powerless optical splitters are used to enable a single optical fiber to serve multiple subscribers. A PON consists of an OLT - optical line terminal at the service provider's central office, passive splitters, and a number of ONU - Optical Network Units near end users. A PON reduces the amount of fiber, central office equipment and overall power consumption required, compared with point to point architectures. Maximum number of ONU that can be connected to a single PON port of the OLT using our equipment is 64. This way up to 256 subscribers can be serviced using a 1U rack-mountable OLT with power consumption of a standard 24-port SFP switch. Our end-to-end GEPON solution supports QoS- Back-pressure flow control (half duplex), IE 802.3x flow control (full duplex), IE p802.1p, CoS WR, SP and FIO, Supporting the Mark/Remark priority of 802.1P/DSCP, Limiting the uplink/downlink rate based on each ONU, Supporting DBA and SLA , VLAN - Port-based VLAN, GVRP, IE802.1Q VLAN relay, Supporting QinQ and flexible QinQ, IGMP Snooping.
