16 XLR broadcast audio Optical fiber Mux

1-16 integrated multiplexing audio optical transmitter / receiver using digital coding technology, audio interface XLR (XLR), can be audio signals, data signals, switch signals and Ethernet signals through a single-mode fiber achieve long-distance two-way transmission, the maximum signal can be transmitted without distortion-free relay 100Km. Audio interface with 24Bit AD / DA, 128K sampling, studio-level transmission quality.

The fiber audio multiplexer is composed of optical transmitter and optical receiver, can be Set to 8 channel bi-directional audio and 16 channel unidirection audio.
