The S/P-DIF (Sony Philips Digital InterFace), which arrived in 1983 along with the CD, is still very much a part of our world today. Transmitted through Toslink fiber optics cable, it is still one of the most important cables in electronic entertainment. Hence why AudioQuest has refined and renewed our line of serious high performance OptiLink cables. When the question is “how can a fiber-optic cable change the sound?” The answer is easier to explain than for almost any other type of cable. If the light source were a coherent laser, firing into a vacuum, all the light would stay straight, arriving at its destination at the same time. Even if the LED light source in a Toslink system were coherent, the light entering a fiber-optic cable is scattered and dispersed by imperfections and impurities in the fiber. This can be measured as a loss of amplitude. But amplitude is not the problem. The problem is that the dispersed light does get through the cable, but only after it has taken a longer path. This delayed part of the signal prevents the computer charged with decoding this information from being able to decode properly, or even at all. The inability to decode shows first at higher frequencies, so reduced bandwidth is a measurable signature of light being dispersed by a fiber. The punch line: The less dispersion in the fiber, the less distortion in the final analog audio signal presented to our ears. There is another serious dispersal mechanism in the Toslink system. The fiber is a relatively huge diameter, and the LED light source is also relatively large, spraying light into the fiber at many different angles. Light rays entering at different angles take different length paths and arrives with different amounts of delay. The almost complete solution to this problem is to use hundreds of much smaller fibers in a bundle. Because each fiber is limited as to what angle of input can enter the fiber, there is far less variety, and far less dispersion over time.

  • Low-Dispersion Fiber
  • Low-Jitter (Digital Timing Errors)
  • Precision Polished Fiber Ends
  • Easy to install
  • Reduce sound degradation
