Combiners
Basic Combiner Characteristics:
1. Passive combiners never require power. They always have loss. Typically: 3-4dB for a 2-way, 6-7dB for a 4-way, 11-12dB for an 8-way, 18dB for a 12-way and 21dB for a 24-way. Losses are offset with the use of an appropriate launch amplifier following the combiner.
2. Active Combiners always require power since they include a built-in broadband amplifier to offset the losses that are inherently incurred through the passive combining of signals. This type of combiner eliminates the need for a separate launch amp.
3. Combiners are available in both rack and non-rack styles.
4. Splitters can serve as combiners. A few companies actually label such a device either as a combiner or a splitter. When using splitters as combiners it is best to select a balanced model that has equal losses on each port. Also, it is important to be diligent in only using the output ports as "inputs" and thus only the input port as the new "combined output". Failure to do this will be catastrophic because of the port-to-port isolation designed into the splitters resulting in serious signal unbalance.
5. When using active combiners, it is imperative not to overdrive with too high of input levels which could result in serious cross-modulation/distortion causing signal degradation on the combined cable channels.
6. The good news on combining is that neither the passive or active models care whether you are using them in an Analog or Digital system. All combiners can be used in either Analog, Digital or Hybrid (combination of analog and digital) systems.
Keeping the above six pointers in mind, selecting the correct combiner for any headend cable system is an easy task.
