Extend optical digital cables
If you want to make a long one out of two optical digital cables, you can easily build a rail with two toothpicks and adhesive tape. Simply hold the two ends of two cables in front of each other, then hold the two toothpicks (one on the left and one on the right) next to them and wrap them in layers with adhesive tape (test first to see if the signal arrives). There is no bad signal for digital connections. Either the sound is there or not. Have already made one of three cables to have sound on the balcony. By the way, three different brands. Cables are all standardized. Manufacturers do not matter.
