TOSLINK cables are practical magic. Using light to carry a digital sound signal is no easy feat, and sometimes the perfect project can require just a little too much from a hard-working cable. Most optical audio cables begin to lose signal after approximately 20-30 feet, but that doesn’t mean you have to sacrifice your vision. TOSLINK extenders are an ideal solution for those longer TOSLINK runs. Using just one little box and a bit of electricity, you can boost your signal for up to 82.5 feet without any decrease in sound quality.
