Core functions:

1.Photoelectric conversion: 

convert electrical signals into optical signals, or vice versa.

2. Extend transmission distance: 

break through the transmission limitations of standard TOSLINK optical fibers and support longer distances.

3. Anti-interference isolation: 

use the insulation properties of optical fibers to eliminate electromagnetic interference and ground loop noise.

Technical features

1. Interface standard:

Adopts the Toslink standard square optical fiber interface, and the device-side interface is often marked "Optical", which supports compatibility with optical fiber cables and adapters of the same standard.

2. Transmission format:

Supports mainstream digital audio formats, including two-channel PCM stereo, Dolby Digital, DTS and other compressed surround sound, but due to bandwidth limitations, generally does not support Dolby TrueHD, DTS-HD Master Audio and other high-resolution audio.

3. Anti-interference ability:

Use optical signal transmission to completely avoid electromagnetic interference, radio frequency interference and ground loop problems, especially suitable for home theaters, professional audio and other scenes with high requirements for sound quality purity.

4. Application scenarios：

Widely used in home audio-visual systems and professional audio equipment connections,

For example: connecting Blu-ray players, game consoles, set-top boxes with amplifiers, soundbars;

Extending the audio signal transmission between TVs and surround speakers; Interference-free audio transmission between devices in professional recording studios.

In short, the Toslink fiber optic transceiver is a device based on the Toslink standard that realizes long-distance, anti-interference transmission of digital audio signals through optoelectronic conversion. It is the core conversion component of the signal link in the digital audio system.
