In an optical audio setup, the digital electrical signal from the source -- say, a DVD player -- is converted into light by a device called a transmission module. In Toslink, this module consists of an LED, or light-emitting diode, and a drive circuit, usually sent through plastic fiber, whereas ST Fiber Optic uses glass fiber and a red laser light at a 680-nanometer-wavelength …

TOSLINK - Wikipedia
https://en.wikipedia.org/wiki/TOSLINK
TOSLINK is a standardized optical fiber connector system. Also known generically as optical audio, its most common use is in consumer audio equipment, where it carries a digital audio stream from components such as CD and DVD players, DAT recorders, computers, and modern video game consoles, to an AV receiver that can decode two channels of uncompressed …
What Is an Optical Cable Splitter? (with picture)
https://www.easytechjunkie.com/what-is-an-optical-cable-splitter.htm
Optical cable is one of two main types of cable used for digital audio signals, the other being known simply as digital cable. The optical cable transmits light signals rather than electrical pulses and can be distinguished by its transparent plug that will display a light when unplugged during use.
Toslink vs Optical: What is The Difference? | Finddiffer.com
https://finddiffer.com/toslink-vs-optical/
This type of audio cable converts electric audio signals to light with wavelengths higher than 680nm. These signals are then transmitted through glass, plastic, or silica fiber. In short, a Toslink cable is a digital audio cable (optical fiber) that transmits audio signals through light pulses instead of electricity.
SPDIF vs. Optical – What Is SPDIF and What Is Optical ...
https://finddiffer.com/spdif-vs-optical-what-is-spdif-and-what-is-optical/
With the optical format, the output signal that travels through the cable must be changed or converted from an electrical one to an optical or light-based one. After the signal has reached the optical receiver or input, it undergoes conversion again from optical to electric. Optical was partly developed in order to combat Radio Frequency Interference (RFI) and Electromagnetic …

What is PCM Audio? [Format Difference. Expert Explaned]
https://samplerateconverter.com/educational/pcm-audio
Audio signal in musical system (amplifier, AV-receirer, etc.) is altering voltage same to acoustical waveform changing. Special device - analog-to-digital converter - rapidly measure momentary values of the audio signal (its voltage). These values may be converted back to the audio signal via digital-to-analog converter device. Read details below.
