Sencore VB266 QAM DVB-C/C2 Dual Monitoring Blade

The Sencore VB266 QAM DVB-C/C2 RF Input Blade brings support for the latest cable modulation standards to the VideoBRIDGE product line. With support for QAM16 all the way to QAM4096, the VB266 includes all the modulation formats needed for modern networks with high-density MPTS transports. Each VB266 includes two independent tuners. One is enabled by default and the other is enabled with the VB266RF-LICENSE. Together with the VB120 or VB220 controllers, this allows up to 4 RF inputs in a 1RU chassis.

A complete configuration with a fully licensed VB120 provides real-time monitoring and alarming for 4 QAM inputs, 50 IP MPTS/SPTS multicasts, and an ASI TS input and output. ETSI TR 101 290 analysis and monitoring is performed in parallel for the QAM inputs, the ASI input and the IP input. If a VB220 is used as the controller, the IP monitoring capacity is increased to 260 MPTS/SPTS multicasts in addition to the RF inputs.

The combined unit is ideal for hybrid networks where IP is used as a carrier from head-end to the regional edge multiplexer/modulator. The built-in round-robin functionality allows sequential analysis of multiple QAM multiplexes, making it possible to monitor the total broadcast contents of a cable transmission system using a single VB266. The VB266 QAM DVB-C/C2 input blade is an ideal solution for complete monitoring in DVB-C/C2 or hybrid DVB-C/C2/IP networks. One VB266 module is capable of demodulating two multiplexes (one per input) for ETSI TR 101 290 fault detection and alarm generation in the full frequency band (44-1000 MHz).
