Schwaiger Optical Digital Audio Cable TOSLINK to TOSLINK S/PDIF Plug to Plug 1.5m Black

The Schwaiger LWL2150533 is a 1.5 m optical digital audio cable with a TOSLINK plug on each end, for carrying the digital sound from a TV, DVD/Blu-ray player, console or set-top box to a soundbar, AV receiver or DAC. Schwaiger names DVD player to AV receiver with Dolby Digital or DTS as its typical use.

Optical means the audio travels as light, so there is no electrical connection between the two devices — no hum loops and no interference from nearby power cables. The plugs are robust plastic TOSLINK connectors that click into the square optical socket.

• 1 × Schwaiger optical digital audio cable (Lichtwellenleiter Anschlusskabel), TOSLINK plug to TOSLINK plug, 1.5 m, black — per Schwaiger

• 1.5 m is the usual distance from a TV to a soundbar or from a player to a receiver on the same unit or shelf.
• Remove any transparent protective caps from the plug tips before inserting, then push the plug straight in until it clicks; the socket only accepts it one way round.
• On the TV or player, set the digital audio output to Auto/Bitstream for Dolby Digital or DTS surround, or to PCM for plain stereo, and select the optical input on the soundbar or receiver.
• Avoid sharp kinks and do not trap the cable behind furniture — the light path is in the cable, and a crushed or tightly folded cable loses the signal.

• HDMI ARC/eARC connections — this is an optical cable only; it does not plug into HDMI.
• Lossless and object-based formats such as Dolby TrueHD, Dolby Atmos (TrueHD), DTS-HD MA and multichannel PCM — optical S/PDIF carries stereo PCM or compressed 5.1 (Dolby Digital, DTS) only.
• Coaxial digital (RCA) or analogue (RCA/3.5 mm) audio sockets — these are electrical, not optical.
• Devices with only a 3.5 mm Mini-TOSLINK jack, unless you add a TOSLINK to Mini-TOSLINK adapter.
