16 Channel Broadcast XLR Audio over Fiber Converter

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

The audio optical transceiver comprises an optical transmitter and an optical receiver, which can be set to 8-channel bidirectional audio mode and 16-channel unidirectional audio mode.

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

● Audio interface XLR balanced 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 uses 24Bit AD/DA128K sampling, and it has studio-grade transmission quality

● It provides bidirectional asynchronous data (forward and reverse)

● Asynchronous data transfer rate than 110-115.200Kbps

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