8Ch Broadcast XLR Audio to Fiber Converter

View : 346
Type : Audio Fiber Mux
Description :

This product uses digital coding technology, and the audio interface is XLR.


This product adopts digital coding technology, the audio interface is XLR, which can realize bidirectional long-distance transmission of audio, data, dry contact and Ethernet signals through a single-mode optical fiber. The maximum transmission distance without distortion and without a repeater is 100 km. The audio interface adopts 24Bit AD/DA128K sampling, with studio-level transmission quality.


The audio optical transceiver comprises an optical transmitter and an optical receiver, and it can be configured into 4-channel bidirectional audio mode and 8-channel unidirectional audio mode.
