Wi-Fi 802.11b/g/n
Wi-Fi 802.11a/n/ac

ONT NTU are high-performance network terminals which are designed for providing access to voice services, IPTV, OTT, high speed Internet. Also, with NTU-RG series optical network terminals, operators will be able to provide their subscribers with a wide range of local network operation services and capabilities.

PON Technology
PON Technology is the most modern and effective “last mile” solution. This solution reduces the amount of cable and provides data transfer with downlink rate up to 2.5 Gbps and uplink rate up to 1.25 Gbps. PON-based solutions in access networks allow end users to have access to a set of services based on IP protocol.

Universal Devices
Integrated 4-port1 10/100/1000 Base-T Gigabit router allows to create a high-performance connection for network devices. FXS port enables VoIP services. The USB port can be used for USB-enabled devices (USB flash drives, external HDD, printer).

Supported services:

High-speed Internet access
Video streaming/ High Definition TV/IP TV, Video on Demand (VoD), Video conferencing
VoIP
Online educational and entertainment programs

Applications

Providing of broadband access services to subscribers located in apartment houses, residential areas, campuses or suburban settlements
Corporate network construction at large strategic enterprises, or in office buildings with high requirements in terms of security and data transfer rates

Wireless Connection
NTU-2W user routers allow you to connect Wi-Fi clients via IEEE 802.11b/g/n standard.
