Balance or unbalance Audio Fiber Optical Transmitter

DLX-DVOPA Series Digital audio/data fiber transmitter and receiver provide uncompressed high quality real time transmission for Stereo or Mono Bi-directional or Single-direction audio signals over one single mode or multimode optic fiber.

DLX-DVOPA Series products adopt 24bits High Dynamic Range audio technology, support High fidelity, stereo audio undistorted transmission. Support various format and protocols, has good adaptability. SNMP module optional, support manage remote end and local end transmitter and receiver.Can been installed rapidly without customer adjusting, and they are easy to operate and maintain. On the front panel of the products are video connector (BNC), audio and data connector (RJ45 or Terminal Plug with screw clamps), and fiber optic connector (FC-single mode or SC-multimode). Users can easily monitor the status of power supply, connection and channels through the indicator lights. There are two types of DLX-DVOPA available: standalone and card type.
