8 XLR broadcast audio Optical

View : 244
Type : Audio Fiber Mux
Description :

Audio Optical by the optical transmitter and optical receiver can be configured with 4 channel audio and 8- channel audio mode.


1-8 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.

Audio Optical by the optical transmitter and optical receiver can be configured with 4 channel audio and 8- channel audio mode.



●  All-digital fiber optic transmission platform, multi-service platform with flexible configuration

●  Audio interface XLR balanced XLR interface, audio power supply for the high-power toroidal transformer, + – 18V power supply, high dynamic range;

●  Provide ordinary desktop mini-desktop, centralized card rack in various ways

●  Data interface and audio interface provides three mine-protected, through the ITU-T K.21 (10/700 μS), common mode: 6KV, impedance (40 Ω) test

●  Single fiber transmission, optional dual fiber

●  Can receive no light is detected, the remote device is a power failure or fiber cut

●  Audio using 24Bit AD / DA, 128K sampling, studio-grade transmission quality

●  Provides bi-directional asynchronous data (forward and reverse)

●  Asynchronous data transfer rate than 110-115.200Kbps

●  Asynchronous data for RS232 / RS485 / RS422 / Manchester code
