Experience superb sonic clarity and accurate musical reproduction with this Premium S/PDIF (Toslink) Digital Optical Audio Cable from Monoprice!The Sony/Philips Digital Interface Format (S/PDIF) provides for a Digital Optical Audio signal, commonly referred to as Toslink.

Being an optical signal, Toslink is immune to problems that can plague electrical signals, such as crosstalk, magnetic interference, or radio frequency interference.This premium cable features a full-sized Toslink connector on each end, with metal connector heads and a metal mesh jacket. The metal jacket helps protect the cable from nicks, cuts, and kinks, which could cause damage to the internal optical fiber.
