The length where the fibre finally matters
Pxyelec S/PDIF Toslink optical cable, 10 m
The long run on this shelf — and the one where the unstated fibre material stops being a detail and becomes the specification.
The length changes which specification matters
At one or two metres, the fibre material is academic. At ten metres it is the specification: plastic (PMMA) is generally reliable to about that distance and glass goes considerably further. This listing says high-quality fibre core and does not name the material, which is exactly the length at which naming it would matter.
Dolby Digital and DTS. It stops where the standard stops, unlike several listings on this shelf that claim lossless formats Toslink cannot carry. That is worth noting in a cable’s favour.
The ADAT mention
ADAT is an eight-channel optical protocol used by recording interfaces, carried over the same connector. It is irrelevant to a television and useful to know if the far end of this run is a studio interface rather than an amplifier.
The reason to run ten metres of optical at all
Hum. Two devices at opposite ends of a room, on different mains circuits, joined by an analogue cable, is how a ground loop forms. Light breaks the electrical connection completely, and that is what you are buying at this length.
The alternative
If both ends support HDMI eARC, that connection carries everything optical cannot. Optical stays the right answer when one end is old.
