The audio signal indicators of Tianwei Telecom's broadcast grade optical transceiver exceed the broadcast grade A standard; The audio sampling accuracy reaches 24Bits, the audio signal-to-noise ratio is over 90dB, and the power supply has dual backup, making it the preferred brand for high-end applications.
Broadcast grade optical transceivers are mainly used for broadcasting systems in areas such as broadcasting, television, telecommunications, power, public security, military, highway transportation, customs, large factories and mines, as well as video/audio transmission systems for cable television stations. They have the characteristics of compact size, easy use, wide dynamic range, and high cost-effectiveness. The optical transceiver adopts reliable optical module components with a large optical dynamic range. The equipment does not require debugging, is plug and play, stable and reliable, and can adapt to various working environments.

An audio optical transceiver is an audio device that converts traditional audio analog signals into optical signals at the transmitting end, transmits them through optical fibers to the receiving end, and then converts them into analog signals at the receiving end.
The audio optical transceiver is divided into 1 to N channels of audio, and attention should also be paid to the details of monaural/binaural (i.e. stereo), unidirectional/bidirectional, balanced/unbalanced output in the audio.
The several important indicators of audio optical transceiver are:
1) Bit rate: 16bits, 20bits, 24bits, the higher the bit rate, the more finely it can reflect the subtle changes in sound.
2) Sampling accuracy: 48K 96K (CD sampling accuracy is 44.1KHz/s), professional audio optical transceivers generally use 48K sampling, and 96K is a future direction.
3) Signal to noise ratio, commonly known as dynamic range, is measured in dB. The relationship between dynamic range and bit rate is that for every 1 bit increase in bit rate, the dynamic range increases by 6dB. At 16 bits, the dynamic range is 96dB. This can meet general requirements, and 24 bits can achieve a dynamic range of 144 dB, which is at a high level. So the current professional optical transceiver specifications can be summarized as: 24 bits, 48K sampling, 90DB.
