RF diplexer
In a cable network system, it may be possible to combine or separate upstream and downstream signals by using a 2-way splitter (and filters).
However, the 2-way splitter cannot effectively isolate the two frequency bands, interference between upstream and downstream is often a problem. In addition, because the insertion loss of the general 2-way splitter is about 3.5~4dB, it will cause excessive loss to the signal.
To properly solve this problem, you need to use a rf diplexer to replace the 2-way splitter.
The RF diplexer is a wideband, high performance cable network diplexers.
