An optical digital audio connection sends stereo or 5.1 S/PDIF digital audio between devices. What is this? An everyday use for this type of connection is the digital audio output on the back of your TV. By connecting this output to an amplifier, you can quickly improve the sound of your television.
Is an optical cable better than HDMI?
The major difference is that HDMI cables can pass higher resolution audio which includes formats found on Blu-ray like Dolby TrueHD and DTS HD Master audio. Fiber optic cables won’t be able to transmit these high-res sound formats. HDMI can also pass video signals. Here, optical cables will be the perfect fit.
Does digital optical cable make a difference?
Both HDMI and optical pass digital audio from one device to another. Both are better than analog (the red and white cables). The biggest difference is that HDMI can pass higher-resolution audio, including the formats found on Blu-ray: Dolby TrueHD and DTS HD Master Audio.

The digital audio bit stream is transmitted using pulses of light through this optical cable. A Digital Coaxial connection uses a cable that has RCA-type connectors.
What does optical mean in music?
Optical sound is a means of storing sound recordings on transparent film. Optical sound has also been used for multitrack recording and for creating effects in some musical synthesizers.
Does optical cable affect sound quality?
So if you’re getting a Dolby Digital signal, and it’s not cutting out, your optical cable is fine. If you’re transmitting PCM, the audiophile answer is that different optical cables can cause different amounts of jitter. The reality is, the digital-to-analog converter in your gear has vastly more effect on the sound.
Do I need optical cable for surround sound?
