Star Network Aduio Fiber Transceiver

The star formation broadcast audio for broadcast audio Optical fiber networks to achieve a transparent stereo audio transmission over fiber optic star network. As a result of the fiber as a transmission medium, you can completely avoid the threat of harsh environments lightning, surges, electromagnetic interference to the device.

Central office all the way to eight stereo audio transmitter fiber direction, distal to eight stereo audio receiver, convenient outlet management for a home stereo audio to eight breakout broadcast applications.
