My optical cables are from Blue Jeans Cable, as are most of my others. The reason I am using multiple cables is I have a built in cabinet for the entertainment center. I am running everything from the back of the center, through a wall to a four gang wall plate with keystone jacks to plug the TV, speakers, etc. into. I like the clean installed look.

I was surprised that two 4ft cables with a jack worked but a 9ft and a 4ft with a jack would not. It is starting to look like I might have to run a single cable through a modified keystone cover to get this to work. It won't look as nice but it should work.
