Reverse a splitter to combine signals from different antennas. Splitters contain no electronic devices and don't require any power, making them "passive" instead of "active. " Because of this, they can be connected in reverse without any damage. Typically, but not always, there is one input in and multiple outputs. Light power goes in and light power coming out of the various legs is reduced in. Do I use a splitter in reverse in this situation or do I use a combiner? Cause from the viewpoint of the cable TV/internet signal and the MOCA endpoint nearby I'm combining signals but from the viewpoint of the MOCA endpoints in the rest of the house I'm actually splitting signals. Or should I. I have an optical output on the back of my blu-ray player, which I would like to split to connect to two amplifiers. What kind of splitter or device do I need to achieve this (hopefully maintaining decent signal quality/strength)? I have seen basic splitters on ebay for under £3, but are these any. The Passive Optical Network (PON) is an optical access network infrastructure that uses passive optical components, such as optical fibers, connectors, and optical splitters, to dis-tribute an optical signal.
