• A well assembled Toslink Optical cable is not hard to make, as long as it is not too long. Use a good size core of proper quality POF cable, cut, polish and terminate. As long as all this is done well, it should work very well. Long lengths and Connector choices are where it gets interesting. For long lengths, and that means somewhere between 10-20 feet, you have to upgrade the POF "conductor" to higher grade acrylics or even glass fibers. • Connectors in this case are not electrical and should only be considered on their physical characteristics. Light, plastic, small connectors are often best with older components with worn Toslink connectors. The less weight in a worn connector, the less likely to be jostled loose enough to skew off of center. Light, flexible cable is the best match for this scenario. The scenario for a heavier connector is when a receiver is on the same stand as the center speaker - so that vibration can effect the toslink connector, then a heavy, solid connector is desirable. In any case, a good, quality made connector will more precisely fit, so will reduce your risk of digital errors.
