How do I know which digital audio optical cable to buy?

Question

I want to connect an optical audio digital cable from my comcast receiver to my surround round receiver There are so many.How do I know which one, or are they all pretty much the same? It needs to be about 6 ft long. Can I tell the differance between them?

Answer 1

While they are similar, there is plastic optical fibre cables (cheaper) and Glass optical fibre cables(more delicate).

Check out PartsExpress.com for both types.

The glass ones will break if bent sharply, but so can the plastic ones if abused.

Glass will not dis-color with time like plastic can.

Hi,

   Its all marketing just make sure the cable ends fit your transmitter and reciever and the cable is 6ft long, next look for the cheapest price they all do the samething.

Answer 3

well as long as it has the length you need buy the cheapest one. a digital signal is either all there  or not there at all. so as long as the cable transfers the signal it will sound every bit as good as an expensive optical cable.
