8Ch Broadcast XLR Audio to Fiber Converter

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.

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

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

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

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

● Single fiber transmission, dual-fiber optional

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

● Audio adopts 24Bit AD/DA128K sampling, 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
