Product Details

Product description

The 1-8 channel integrated multiplexed audio optical transmitter/receiver adopts digital encoding technology, and the audio interface is XLR (XLR). It can realize long-distance bidirectional transmission of audio signals, data signals, switch signals, and Ethernet signals through a single-mode fiber, and can transmit signals without distortion or relay for up to 100Km. The audio interface adopts 24Bit AD/DA128K sampling, with studio level transmission quality.

The audio optical transceiver is composed of an optical transmitter and an optical receiver, and can be configured with 4-channel bidirectional audio and 8-channel unidirectional audio modes.

Features

◆Fully digital fiber optic transmission platform, flexible configuration of multiple services on the same platform;

◆The audio interface is XLR XLR balanced head interface, and the audio power supply is a high-power ring transformer+-18V power supply with high dynamic range;

◆We can provide various ways for ordinary desktop, mini desktop, and centralized plug-in card racks;

◆The data interface and audio interface provide three-level lightning protection function and can pass the ITU-T K.21 (10/700 μ S) common mode: 6KV impedance (40 Ω) test;

◆Single fiber transmission, optional dual fiber;

◆Can detect whether the remote device is powered off or disconnected when there is no light received;

◆The audio adopts 24Bit AD/DA128K sampling, with studio level transmission quality;

◆Provide bidirectional asynchronous data (forward and reverse);

◆Asynchronous data with a transmission rate of 110-115.200Kbps or higher;

◆Asynchronous data can be RS232/RS485/RS422/Manchester codes.
