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 cables and provides data transfer with downlink rate up to 2.5Gbps and uplink rate up to 1.25Gbps. PON-based solutions in access networks allow end users to have access to a set of services based on IP protocol.
