For me, unfortunately, no luck ...

Like many others here I was faced with the problem of having to only have to perform an optical input on my amplifier, two sources with an optical digital output (a computer and a Playstation). From a scientific curiosity I have to the optical Y-adapter despite the very mixed reviews ordered and tried.

For the statistics: in my case, it has unfortunately not working. I have of course taken to ensure that only one of the two signal sources is on. Nevertheless, the amplifier has detected no signal. We seems to me, is in the Y-adapter too much light is lost or is not good enough is coupled into the optical waveguide. In any case the visible light intensity is reduced by the intermediate switches of the adapter clear. This does not seem to get along all amplifiers.

Instead, if you subtract each unused line to see their connection a light signal. There are in the device so obviously reflections and scattering, which in turn suggests an improper processing.

I give two stars for the mere idea of ​​establishing such an optical Y-adapter. Pity he did not (at least not at all) works reliably. Other alternatives are orders of magnitude more expensive, uncomfortable, and require their own power supply.
