1-8channels of integrated audio audio optical transmitter / receiver adopt digital coding technology, and the audio interface is RCA (Lotus seat), which can realize audio signals, data signals, digital signals and Ethernet signals through a single-mode fiber Distance bidirectional transmission, the signal can be transmitted up to 100Km without distortion without repeating.
Severalimportant indicators of audio optical transceivers are:
A、Bit rate：16bits 20bits 24bits，The higher the bit rate increase, the more subtle changes in sound can be reflected.
B、Sampling accuracy：48K 96K 128K 196K (CD sampling accuracy is 44.1KHz / s)，Professional audio optical transceivers generally use 48K sampling, 96K, 128K, 196K is a future direction.
C、The signal-to-noise ratio is what we usually refer to as dynamic range. The unit is DB. The relationship between dynamic range and bit rate is: for each bit increase in bit rate, the dynamic range increases by 6 dB. At 16 bits, the dynamic range is 96db. This can meet the general needs, and 24 bits can achieve a dynamic range of 144 dB, which is fever-grade. So the current professional optical transceiver specifications can be summarized as: 24bit 48K sampling 90db.
Our audio optical transceiver, the audio interface uses 24Bit AD / DA, 128K sampling, studio-grade transmission quality.
The audio optical transceiver is composed of an optical transmitter and an optical receiver, and can be configured into 4 (2 stereo) two-way audio and 8 (4 stereo) unidirectional audio modes.
