The possibilities offered by HDMI, USB, FireWire® and Ethernet connections are creating a lot of movement on the audio front. However, the current generation of digital technologies is only part of the story; the challenge of designing, manufacturing and selecting the best analogue cables and speaker cables still remains. S/PDIF (Sony® Philips Digital InterFace), which emerged in 1983 at the same time as the CD, is still part of the audio world. S/PDIF is transmitted over digital coax and Toslink fibres, making these still the most important cables in electronic entertainment.

While HDMI is more commonly used than Toslink to connect a DVD player to an AV receiver, Toslink connections are common on cable boxes, TVs, subwoofers, and all sorts of other products. Now the 3.5mm miniplug, also somewhat incorrectly referred to as mini-Toslink, can be found just about everywhere - from the 3.5mm headphone jack on a Mac laptop to inputs on some of the highest-end portable devices.

For these reasons, we at AudioQuest have improved and updated our line of high-performance OptiLink cables. All models and lengths are now available in Toslink to Toslink and Toslink to 3.5mm miniplug versions.

The question 'How can a fiber optic cable change the sound?' is easier to answer than for any other type of cable. If the light source was a coherent laser beam projected into a vacuum, the light beams would remain straight and all arrive at their destination at the same time. Even if the LED light source in a Toslink system were to shine coherently, the light would be scattered as it entered the fiber optic cable due to defects and impurities in the fibers. This is measurable as amplitude loss; however, amplitude is not the problem: 50% loss would have no effect on sound quality.

The problem is that the scattered light travels through the cable but does not take the direct route - like a billiard ball being played over the rail, which takes longer to reach its destination than one that rolls the most directly. This missing piece of the signal prevents the computer responsible for decoding it from doing its job correctly - or at all. The difficulties in decoding first appear at the higher frequencies (not audio frequencies, as this is a mono stream of digital audio information), so reduced bandwidth is measurable evidence of light scattering through the fibers. The consequence: the less scattering in the fiber, the less distortion in the audio signal that ultimately reaches our ears.

There is another serious scattering mechanism in the Toslink system. The fiber is relatively thick at 1.0mm diameter and the LED light source is also relatively large, so the light is 'sprayed' into the fiber at many different angles. Even if the fiber was absolutely perfect, there would be time shifts in the signal because the light bundles enter the fiber at different angles and therefore travel different distances before arriving with different amounts of delay. A comprehensive solution to this problem is to combine hundreds of much smaller fibers into a 1.0mm bundle. This limits the angles at which the light can enter this fiber, there is much less variation and therefore less scattering over time. This effect achieved by the narrow aperture is similar to the principle behind a pinhole camera that can take photos without a lens: by only letting the light through at a limited angle, the camera can take a photo - if you remove the lens from a camera with a larger aperture, photography would be impossible. Less light passes through a multi-fiber cable, but the light that travels through the cable arrives at the other end within a much smaller time window.

So the problem is the scattering of light over a period of time - there are two ways to get better results: less scattering in the fiber (better polymers and ultimately quartz) and less scattering by limiting the angle of incidence. Simple but true. Listen and enjoy.
