NTU-RG1421G-WZ – a high performance multifunction customer premises terminal that is designed to connect to modern telephony, IPTV, OTT services and for high-speed access to the Internet. Furthermore, NTU-RG series terminals allow providers to offer their clients a wide range of services and opportunity to work in a local network.

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

Universal device
The integrated gigabit router for 4 ports of 10/100/1000BASE-T ensures high-speed connection on 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).

Provided services
  • High-speed access to the Internet
  • Stream video/High Definition TV/IP TV, Video on Demand (VoD), video conference
  • IP telephony
  • Online educational and entertainment programs
  • “Smart home” management
  • Providing broadband access services to subscribers in apartment houses, residential areas, campuses or suburban settlements
  • orporate network construction at large strategic enterprises or in office buildings with high requirement in terms of security and data transfer rates
Wireless connection
NTU-RG-1421G-WZ supports IEEE 802.11ac standard, that provides data rates up to 1300 Mbps and deliver modern high performance services to client equipment trough the wireless network. Two integrated Wi-Fi controllers ensure simultaneous dual band operation: on 2.4 GHz and 5 GHz.

“Smart home” controller
The device contains integrated controller for “Smart home” system. The controller provides interaction with sensors and detectors through the wireless channel.

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