      DOAL01 (Digital Optical Audio Link) is a high-quality audio digital optical fiber connector, usually used in those occasions that need to obtain audio from a poor RF environment, such as extracting audio data from radiation sensitivity testing in a dark room, The system is bi-directional, half-duplex and uses fiber optics for the connection.

      One end of the system is connected to the audio generation or extraction equipment (speaker/microphone) exposed to the RF environment, and the other end is connected to an audio analyzer or audio generator. The purpose is to obtain audio signals from the anechoic chamber for analysis or to convert accurate Audio signals are injected into the darkroom. The audio data stream format used is 24bit, 48KHz sampling rate, standard S/PDIF encoding format, digital S/PDIF encoding on the control side provides analog output at the same time.

      The system consists of the following components:

      DOAL01T-B, the transmitting module, is placed in an environment exposed to RF (such as an anechoic chamber or GTEM chamber), powered by batteries, and shielded, which can take into account both transmission and reception. The battery uses a 12V charger, and the input and output only Using one connector, there is an on/off switch on the front panel, with a pair of LED indicators to indicate power on/off and battery status.

      CB2, 12V battery charger, used to charge the battery of DOAL01T-B;

      DOAL01R, the basic module, placed on the control side, taking into account both transmission and reception, using an external 12V power supply, and an electrical connection with an external audio analyzer or signal generator (not connected at the same time), with an on/off switch on the front panel , with a pair of LED indicators, which respectively indicate the power on/off and the status of the fiber connection. The module does not use shielding design, because it is designed to be used in general laboratories.

      AL2, 12V external power supply, used to power DOAL01R;

      FB020, optical fiber, 20 meters long, for connecting DOAL01T-B/ DOAL01R;

      DOAL01-MIC, shielded microphone for acquiring audio signals;

      DOAL01-MIC, shielded loudspeaker, user generates audio signal.
