Product details
product description
The 1-16 channel integrated multiplexed audio optical transmitter/receiver adopts digital encoding technology, and the audio interface is XLR (XLR). It can realize long-distance bidirectional transmission of audio signals, data signals, switch signals, and Ethernet signals through a single-mode fiber, and can transmit signals without distortion or relay for up to 100Km. The audio interface adopts 24Bit AD/DA128K sampling, with studio level transmission quality.
The audio optical transceiver is composed of an optical transmitter and an optical receiver, and can be configured with 8 bidirectional audio channels and 16 unidirectional audio channels.
Functional Features
