I would like to connect the digital output from the TV to my receiver. However, the TV only has an optical output for the digital signal. I need about an 8 ft cable from the TV to a wall jack, about 15 ft of in wall cable, and maybe 3 ft cable from the back of the entertainment center to the receiver.

This is way too far for the cheap plastic optical fiber (POF) to carry a signal with 3 cables. I have got it to work with two 4ft cables and a single wall plate. But even a 9ft and 4ft with a wall plate looses too much strength to use.

Would better cables (quarts or glass) work or will I need to use an optical to coax converter and run coax all the way? Or is there a booster that will increase the signal strength to make it usable?
