VX-268 Coxial Digital Concentrator Datasheet

Versa Technology’s VX-268 is based on the New QAM /QPSK modulation technology and it is specially designed for Luxury Cruse guest rooms or Railway High Speed Trains between the Compartments via HFC network to offer broadband network services such as internet, VOD entertainments to their passengers in the guest rooms through legacy coaxial lines.

With channel bonding technology, VX-268 Digital Concentrator can utilize up to 16-QAM channels to achieve downstream (DS) data rates of up to 1.1Gbps; and utilize up to 4 QPSK/QAM channels to achieve upstream data rates of up to 160MBPS.

The system unit’s downstream can be configured to data channels or IP QAM channel. The unit provides 1 Ethernet GE port and 1 SFP GE optical port. With layer 3 routing functions and perfect QoS. The system unit can operate in a variety of working conditions to meet different customer’s requirements. With high bandwidth capacity and perfect QoS features, It is a ideal solution for I(IPTV and Video on Demand (VOD) applications

The compact enclosure form factor of the VX-268 digital Concentrator with the cost-effective rich feature, it is suitable to deploy a small-scaled network for Luxury Cruse or Railway High Speed Trains via existing legacy HFC networks among the guest rooms.
