Product Description:

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.

Functional Properties:

Ø All-digital fiber optic transmission platform, multi-service platform with flexible configuration
Ø Audio interface XLR balanced XLR interface, audio power supply for the high-power toroidal transformer, + – 18V power supply, high dynamic range;
Ø Provide ordinary desktop mini-desktop, centralized card rack in various ways
Ø 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
Ø Can receive no light is detected, the remote device is a power failure or fiber cut
Ø Audio using 24Bit AD / DA, 128K sampling, studio-grade transmission quality

Ø Provides bi-directional asynchronous data (forward and reverse)
Ø Asynchronous data transfer rate than 110-115.200Kbps
Ø Asynchronous data for RS232 / RS485 / RS422 / Manchester code.
