ONT NTU-52VC

Mass production

Key features

1 GPON port
Gigabit router
FXS port for analogue phone connection
RF port for CaTV service providing

NTU series ONT – high performance multifunctional subscriber terminals that are designed to access modern telephony, IPTV, OTT services as well as high-speed Internet. Furthermore, NTU-RG terminals allow carriers to offer their clients a wide range of services and opportunities to work in a local network.

PON technology

PON technology - one of the most effective last mile solutions today. The technology helps to reduce costs for cable infrastructure and ensures data rates of 2.5 Gbps downlink and 1.25 Gbps uplink. The use of PON technology in access networks allows providing end users with access to IP services.

Universal device
The integrated gigabit router for 2 ports of 10/100/1000Base-T ensures high-speed connection of devices in a network. The FXS port provides access to IP telephony services. The USB port can be used for USB device connection (USB flash drive, external HDD, printer).

¹The maximum wireless data rate is defined according to IEEE 802.11n/ac standard. The real bandwidth can be different. Conditions of the network operation, environment, the amount of traffic, building materials and constructions as well as network service data can decrease the real bandwidth. The environment can influence on the network coverage range.
²The value of the maximum output power will vary according to the rules of radio frequency regulation in your country.
