NTU-52W — high performance multifunctional subscriber terminal designed to access modern telephony, IPTV, OTT services, as well as high-speed Internet. Furthermore, subscriber terminal allows carriers to offer their clients a wide range of services and opportunities to work in a local network.

PON technology
PON technology is one of the most effective last mile solutions. The technology allows to reduce costs for cable infrastructure and ensures data rates up to 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.

Provided services
  • High-speed access to the Internet
  • Stream video/High Definition TV/IP TV, Video on Demand (VoD), video conference
  • Online educational and entertainment programs
Application
  • Providing broadband access services to subscribers in apartment houses, residential areas, campuses or suburban settlements
  • Constracting corporate networks at large strategic enterprises or in office buildings with high requirement in terms of security and data transfer rates
Wireless connection
NTU-52W subscriber terminal allows connecting Wi-Fi clients via IEEE 802.11 b/g/n standard.

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 as well.
2 The value of the maximum output power will vary according to the rules of radio frequency regulation in your country.
