Clear digital audio transmission: Optical fiber digital cable delivers clear, full and richly detailed sound by carrying a pure optical signal between devices. Ideal for preserving digital audio quality without electrical interference. Reliable dust protection: Removable rubber caps protect the optical connectors when not in use, preventing dust and preserving signal integrity. Durable, lowmaintenance connectors: Goldplated connector surfaces resist tarnishing, helping maintain conductivity and reliable connections over time. Easy orientation and spacesaving design: Precisely designed cuboidshaped connectors make it simple to identify the correct installation angle and plug in quickly. The compact connector shape also helps keep adjacent ports accessible for other devices. Broad compatibility: Connects DVD, CD, DAT and other digital audio equipment with optical ports. Use it to link players, recorders, receivers and compatible audio components. Materials and function: Optical fiber transmission medium with goldplated connector contacts and removable rubber dust caps for longlasting performance and protection. Typical use scenarios Home theater: Connect a DVD player or a Bluray player to an AV receiver or soundbar for clear, interference digital audio. Hi‑fi listening: Link a CD player or digital transport to a DAC or integrated amplifier to preserve musical detail. Studio or field recording: Connect a DAT recorder or other professional digital audio equipment for reliable optical transfer and protected connectors between sessions. Care and installation tips Keep the removable rubber caps on when the cable is not connected to prevent dust buildup. Align the cuboidshaped connector with the port before inserting to avoid forcing the plug. Store the cable coiled loosely to avoid sharp bends that could stress the optical fiber.
