TESEO

Audio fiber optic links can be point to point or multipoint intercoms.
Multipoint systems are formed of a mixing unit AMU-2 where up to 8 users can talk at the same time under control by an operator that can enable and disable the connections and individually adjust the speech levels. Typically they are designed for large installations with many shielded rooms and other laboratories.

Of course a portable unshielded transceiver (OAL-2) to be born at the belt by the test engineer is available to meet low budget requirements.

OAL-2SL
Point to point connections are more common. An application frequently met is the voice communication between anechoic chamber and control room to connect the test engineer during set-up of the experiment and the test equipment operator. TESEO proposes a shielded loudspeaker (OAL2-SL) with directional microphone in the chamber for hand free operation and desk microphone/loudspeaker in the control room. The shielded equipment also permits the acquisition of sounds during susceptibility tests.
