Fiber Optic Audio Transmission  

 Typical Fiber Optic Audio Application  

The LiteLink® AT/AR-1001 system consists of the AT-1001 transmitter and AR-1001 receiver. The system provides high quality line level audio signals for a multitude of applications including public address systems, intercoms and general-purpose audio point-to-point distribution systems.

Both multimode and single-mode versions are available and installation requires just a single one-minute adjustment. In addition, integral indicators are provided on both units to continuously indicate the presence of audio signals as well as operating power making system troubleshooting simple.

For bidirectional audio see the AX-1001  transceiver. For distribution systems the AM-1004 is a transmitter with one audio input and four optical outputs.
