Toslink is used as an optical transmission cable with the rectangular Toslink connectors in the connection technology of audio devices with Sony/Philips Digital Interface (S/PDIF). In thesimplex version, the Toslink connector is an F05 connector and in the duplex version it is an F07 connector.
The data rate reaches up to 20 Mbit/s. The Toslink cable uses a pure plastic fiber with a diameter of 1 mm. The advantage of optical transmission is the lower susceptibility to interference and the level neutrality: No hum loops can occur due to faulty grounding.
