Maximum length of a Coax SPDIF cable

[bernarga]

I am planing to connect my DVD player SPDIF Coax out to my PC SPDIF in. I need a 15 meter length cable. I dont find 15 m cable in the electronic shops. Some one advice me to use RG-59 coax cable. I know there will be limitation in the length. What is the maximum length of cable I can use? (Safe side).

Please some one help me.

Well, RG-59 is pretty cheap. I would think it would be worth trying. You could also track down some Belden 1505 cable.

i am not an expert on this, so don't bash me if i'm wrong...but i've read up on the web on this because i wanted to do the same thing and, well an spdif cable runs at the same ohms as a regular a/v cable. you can find a/v cables in very long lengths now although i believe the max you should take it is about 30 feet. but i'm sure if you find a very well shielded cable you could get longer. so for your 15 feet i'm sure you can just use any old a/v cable and it would probably even save you money over a "special" spdif cable since they aren't really special cuz they are the same as a/v cables.

If after all the cable does not work, you may try using a repeater. You can get one for up to $50. I have used M-Audio CO2 with great results. Yoe can take a look at it here http://www.minidisco.com/co2.html

Get an RG6, not an RG59.

good quality (not even best ) RG6 type is good for 500' and RG59 is good for 100'

high quality 8281 and air core types for digital sdi transmission (used for SPDIF also) are good for 1000' with no problems at all ..

use proper 75ohm connectors - use the best quality connectors ...




don't make the mistake and buy 110 ohm cable by mistake (also digital audio cable)

Belden 8281 is too difficult to put that type of connector on the ends. The 1505 would be much easier and cheaper to work with. It is good up to about 3 Ghz. We have runs above 300 feet at work with NO problems and SDI traveling on it. If you use 8281 get the 8281F. It has a stranded center conductor so it would be easier to work with. But it is also more expensive.

an even easer to work with cable is the canare equal to 8281 , which is very flexable and have some of the best connectors around ..

since all of this 8281 and canare requires crimpers though (which are expensive for the proper ones , including dies) , best to just go shopping for pre-made cables for the avg user ..

The cheapest RG59 you can find will be totally sufficient for what he wants to do. I have done this for quite some time over a greater distance. RG6 seems to be "too much" for this application on some soundcards.

Yeah, but it's a weaker signal. I switched to all RG6 about a year ago, and my only regrets are that I didn't do it sooner. It cleared up a lot of signal noise and signal problems I was having.

I use "quad-shielded" RG6 myself but only for component video purposes. In my case, rg59 was perfectly fine for audio from my PC to my HT receiver.
