Ah, it's called "edge triggering". Edge triggered synchronous transmission through fiber is a very solid mechanism and all that distortion on scopes I saw in an earlier thread isn't gonna fool it. If triggered on the rising flank, a spike/surge just before the real flank will cause a false trigger but how that would occur in a fiber-optic cable is beyond me so I assume it can't happen. Reflections... let's call it echo's... yes, they will do that which is the reason you need the right connectors and good quality splices... and the cable must be compatible with the connectors, I think I forgot that last one earlier in the thread. Plastic vs glass isn't an issue for these echo's as I'm sure plastic can be spliced just as good as glass. I find it funny that most people here don't even know the difference between basics like single-mode / multi-mode SM/MM fiber but do advise on the plastic vs glass issue. p.s. Nobody is talking about the 15yr old Glenn Farclas? cheers, Nick. -- DeVerm ------------------------------------------------------------------------ DeVerm's Profile: http://forums.slimdevices.com/member.php?userid=18104 View this thread: http://forums.slimdevices.com/showthread.php?t=52817 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
