Need 20 ft long cable -- will optical work?

[douglasbjordan]

I need to connect two devices that are 20 feet apart. The guys at Ultimate Electronics told me that it's better to use digital coax for that distance. Unfortunately, coax is not an option in this case. So I have two options:
1) Use 20' digital optical cable
or
2) Rearrange the room so I can use a shorter length.

I'd rather do option 1. Will this be okay or do you think it'll cause some trouble?

If optical is still good for that length, are there any recommendations on where to by a 20' long cable? None of the local vendors carry them. I want to spend no more than about $30 for it, if possible.

Thanks in advance.

That ain't gonna happen unless you steal some. One of the main downfalls of optical isthat it doesn't lend itself well to being bent and routed as easily as coaxial cable does. Actually, it breaks.

Parts Express does sell coaxial/optical (and vice-versa) adapters but an overall cost of $30 is not a realistic goal here.

This brings up a question back at you. What are you trying to connect with this digital interconnect anyway? Does the source component not have an analog (stereo) output? Or, it does - but you think that the DACs in destination component are "better" and will thus give you "better sound"?

As Mark pointed out in his reply - Toslink optical cable does not take kindly to right-angle bends in its path. So, unless the path between your two devices is fairly straight, you'll be better off not pursuing this type of connection if possible.

If you CAN use the optical cable, there IS one on the market to fill your needs within your budget ($25 plus shipping) from NXG.

I'm chaining devices together across rooms. I have a receiver #1 connected to my computer digitally, and I'm connecting receiver #1 to receiver #2 in the living room. The input source is digital, so it'll go out the digital line from receiver #1 to receiver #2.

When you say right-angle bends, you mean bends over 2" of length or so, right? If I use 8" or so for a smooth curved right angle, that should be okay, right? Who sells the NXG cables? Also, would I be safer spending more and getting this: http://a2zcables.site.yahoo.com/avhd-20.html They're $50 but the site claims to have extra junk in the cables to protect against "bend radius issues."

Thanks for your help so far.

So if I understand you correctly, your "input source" is your computer? And the connection between the computer and your receiver #1 is a digital connection, so you think that you therefore must send those same signals on to receiver #2 (in another room) via a digital link also? Not so, frien'. No matter what your signal source(s) are, they can be output from receiver #1 as analog signals from the "tape output" jacks ... making them available to be sent elsewhere in the home with ordinary audio cables.

If your receiver #1 has a separate "record-out selector", you can then send any audio signal on to the other receiver - regardless of what's being played on receiver #1, if that's something you'd like to do. Or, did you just want to play the same source in both rooms all of the time?

Hope this helps you

Thanks for the response! While your idea would work, my hope is that I might be able to play a DVD-Audio disc in the living room and have it maintain its 5.1 surround in the office where the computer is. (My earlier post didn't really convey that aspect of things -- I just talked about sending my computer's sound to the living room.) That way I can move between the two rooms and be surrounded by sound. For this, I think I'll still need digital cables, and my receivers only have optical outputs so I'm still searching for an optical solution that'll work...

Ahah! The plot thickens!

You started out with the computer as your main source component, and sending signals from it to both receivers. Now, you're talking about playing a DVD-A disc in the living room and sending that signal to the other receiver in your "office". In order to have such functionality and do all of it in the digital domain, you'd need two 20' long optical cables, not just one. The fly in this ointment is that you cannot get a digital output signal from a DVD player when it's playing a DVD-A or an SACD disc ... it's not allowed. Both of those formats require that conversion from digital to analog be done within the player itself, and the output must be in the form of 6 audio cables going to the amp or receiver. You can get a digital output signal from the player when it's playing movies or even musical concerts - provided that the encoding is standard DD or DTS. Seeing that the amount of music that qualifies for this type of interconnect is so limited, I think you should re-think just what you're trying to accomplish here. I think if I were you, I'd be interconnecting the two receivers with analog audio cables (from any record output on each receiver to any input on the other). This will give you just what you say you want to do - plus a lot more versatility than striving to interconnect the two receivers digitally would.

If you still want to pursue the digital connection (a mistake in my opinion) ... I'll get the optical cables for you if you want. But to do what you're now talking about will cost you around $60 - which is considerably more than what you said you wanted to spend.

I'm trying my best to help you here -
