NarrowCast Combiner NQC-1008
The NarrowCast Combiner NQC-1008 takes advantage of the latest GaAs HBT broadband amplifier technology, state-of-the-art circuit board layout, and integration technology to solve the complexities of combining narrowcast channels with cablecast CATV channels. The NQC-1008 is optimized for the isolation requirements of headends that combine analog video, data, telephony, telemetry, or other RF signals utilizing frequency reuse techniques. The unit eliminates dozens of headend connections, increases reliability, and allows the system engineer to efficiently and professionally combine RF narrowcast carriers with broadband CATV cablecast signals.
Applications:
The NQC-1000 should be applied in any network that provides advanced services such as:
- Cable telephony,
- Cable modems,
- Targeted Ad insertions,
- NVOD/VOD,
- Digital video and or telemetry.
The system is optimized to provide very high isolation between the different downstream paths, to allow different RF carriers to operate on the same frequencies in different sections of the network. The high isolation between the narrowcast inputs (two per downstream) and the cablecast inputs, coupled with the isolation of the cablecast splitting network, provides as much as –70 dB isolation between the different downstream paths.
The low insertion loss presented to the narrowcast signals allow them to be input at a lower level, which together with the high isolation of the system, prevents the narrowcast signals from backfeeding into other downstream paths and causing interference problems.
