Its jacket is black/gray stripe in-wall rated PVC. The audiophile world is abuzz these days with the pleasure possible though HDMI, USB, FireWire, and Ethernet connections. However, these current generation digital technologies are only part of the story. The challenge of designing, manufacturing and choosing the best analog interconnects and speaker cables is as important as ever. 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. S/P-DIF is transmitted through Digital Coax and Toslink fiber optics (EIA-J), making them still some of the most important cables in electronic entertainment. Toslink Is Still A Very Vital Link Thanks to the advantages of HDMI, Toslink isn't generally used for connecting a DVD player to an A/V receiver. However, Toslink connectors are common on cable-boxes, TV sets, subwoofers, and all sorts of products. And now the 3.5mm Mini Optical connector (also known as Mini-Toslink) has popped up everywhere - from the 3.5mm dual-purpose headphone jack on a Mac laptop to inputs on some of the finest portables. For these reasons, AudioQuest has refined and renewed its line of serious high performance OptiLink cables. All models and all lengths are now available in Toslink-to-Toslink and Toslink to-3.5mm-Mini-Optical formats. How Can A Fiber Optic Cable Change The Sound? 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. A fifty-percent true loss would have no effect on sound quality. Less Dispersion, Less Distortion The problem is that the dispersed light does get through the cable, but only after it has taken a longer path, like a pool ball bouncing off the side-rails, causing it to arrive later. 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 (not audio frequencies, this is a mono stream of digital audio information), so reduced bandwidth is a measurable signature of light being dispersed by a fiber. In the end, the less dispersion in the fiber, the less distortion in the final analog audio signal presented to our ears. The Multi-Fiber Cable Solution There is another serious dispersal mechanism in the Toslink system. The fiber is a relatively huge 1.0mm in diameter, and the LED light source is also relatively large, spraying light into the fiber at many different angles. Even if the fiber were absolutely perfect, the signal would be spread across time because 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 1.0mm 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. This narrow-aperture effect is similar to how a pin-hole camera can take a picture without a lens; by letting in light at only a very limited range of angles, a picture can be taken, whereas removing the lens while using a wider aperture would make photography impossible. Less light gets through a multi-fiber cable, but the light that does get into the fibers comes out within in a much smaller time-envelope. One Problem, Two Avenues To Better Sound So there is one problem, the dispersion of light across time, and two avenues towards a better result: less dispersion in the fiber (better polymers and ultimately quartz), and less dispersion by filtering the input angle. How simple is that! Listen and enjoy.
