Harmonic Technology's Harmony Optical One Toslink cable is a fiber glass optic digital audio cable that carries digital audio data in the form of light pulses rather than using electricity. The Harmony Optical One Toslink cable is capable of eliminating distortions caused by imperfections of inductance, capacitance and resistance in coaxial digital cable. Toslink cables can also eliminate EMI and RFI interference

Our fiber glass optical cable is designed to provide outstanding low-loss, low-jitter performance while overcoming the usual limitations of cheaper fiber-optic cables. In addition, we have improved the cable's durability and strength, and use connectors that ensure a tight connection every time.
