LTP-8X right





LTE-8X central office node terminal is designed to provide a broadband access over Passive Optical Network (PON). 

8x SFP-xPON ports, 4x 10/100/1000 combo ports, 2x SFP+(10G) ports, L2+ switch, RSSI


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

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

The device has a 1U metal case available for 19” form-factor rack-mount shelf installation.
