Eltex

LTP-8X central office node terminal is designed to provide a broadband access over Passive Optical Network (PON). Access to transport network of provider is realized through 10 Gigabit and combo Gigabit uplink interfaces. GPON interfaces are used for connection to Passive Optical distribution Network (PON). It is possible to connect up to 64 subscriber optical terminals to each interface by one fiber. Dynamic Bandwidth Allocation (DBA) enables to provide downstream rate up to 2.5 Gbps.

LTP-8X application enables operator to build scalable fail-safe “last mile” networks, providing the high level of safety in urban as well as rural areas. OLT LTP-8X provides subscriber devices control, packet traffic switching and connection to transport network.
