Abstract

A mobile phone hands free kit comprising an earphone (1), a microphone (3), and a two-way communication optical fibre link (12) for connecting the microphone (3) and the ear phone (1) to a radio frequency telephone (220). First and second transducer means 10, 14 and 25, 28 respectively) are provided, each of which comprises a first transducer (10, 25) located at one end of the optical fibre link (12) and a second transducer (14, 28) located at the other end of the optical fibre link (12). The first transducer means (10, 14) is operable, in use, to receive electrical signals from the microphone (3), convert the electrical signals into light signals for transmission by the optical fibre link (12(a)), receive the light signals from the optical fibre link (12(a) and convert them to electrical signals to be used by the telephone (22). The second transducer means (25, 28) is operable, in use, to receive electrical signals from the telephone (22), convert the electrical signals into light signals for transmission by the optical fibre link (12(b)), receive the light signals from the optical fibre link (12(b)), receive the light signals from the optical fibre link (12(b)) and convert them to electrical signals to be used by the ear phone (1).
