Question for the digital cable experts...fiber or coax? - Page 2

post #16 of 18
88sound;

The telecom coax cable (for DS3) you described is different from the coax cable for audio. The impedance is different and spec is totally different. As long as you have correct termination the differnce between digital cable is minimal. Major problem with commercial cable is termination. Poor termination causes reflection which results in wrong 1 and 0 and jitter.

The 10 Gbit/s fiber in telecom are single mode fiber and the optic used are 1530 nm laser. The commercial fiber are usually multimode. In audio, they used plastic and 650 nm LED. The limitation on fiber are modal distortion (dispertion of light) and chromatic distortion (distortion of light). Both cause intersymbol interference which corrupt the data.

We can't equate telecom cable with audio digital cable.

dvw,

You speak my language, that's exactly what I was looking for.

Thanks.

Audioadvisor.com sometimes has demos of the GW Lab DSP for $229. That's where I got mine.
