Broadcast XLR audio to fiber optic extender
● The XLR connector is welded to the main board (not the lead of the board) to reduce noise and prevent electromagnetic interference to ensure sound quality;
● The real balanced audio;
● The XLR head cancels the metal shell to avoid interference caused by grounding caused by direct connection with the chassis
This series of broadcast-grade analog audio digital optical transceiver is composed of audio transmitter and audio receiver, used for high-fidelity transmission of analog audio signal AUDIO. In the transmission process, the analog audio signal AUDIO is converted into a digital signal by A/D and transmitted in a digital manner. This series of optical transceivers can transmit 1, 2, 4, 8, 12, 16 AUDIO analog audio signals.
Yite video broadcast-grade analog audio digital optical transceiver, overcomes the conventional analog frequency modulation, phase modulation, and amplitude modulation optical transceiver when multiple signals are transmitted simultaneously. There is serious mutual interference, easy to be affected by the environment, poor transmission quality, and poor long-term stability. Other shortcomings; single-mode (multi-mode) optional, FC/LC/SC optical port optional, transmission distance can reach 0-100km. The audio interface has five levels of lightning protection, anti-static, anti-surge, and anti-electromagnetic interference.
This series of products are widely used in long-distance radio and television transmission systems, remote multimedia teaching, and intelligent traffic monitoring systems.
● 20bit digital codec;
● Audio output port balance/unbalance automatic conversion; ESD protection, safer and more reliable to use;
● The single-stage transmission distance can reach 100Km;
● The system topology can be point-to-point and point-to-multipoint;
● Large audio dynamic range: the maximum input/output audio can reach +18dBm;
● Optional three-level lightning protection function;
● Easy to open, no need to re-adjust on the circuit and optical path when open;
● The working status is clearly indicated, and the panel is equipped with LED indications for input/output audio, optical signals, internal status, and power supply;
● Optional 1310nm, 1550nm, CWDM or DWDM optical transmission mode, through CWDM optical multiplexing to achieve more signal transmission;
● Industrial-grade design, dust-proof, freeze-proof and lightning-proof, high temperature resistance;
● With third-party inspection reports, FCC and CE international certification, 3C compulsory certification, ISO9001 certification
