Founded in 1985, Fraunhofer Institute for Integrated Circuits IIS with its headquarters in Erlangen, Germany, ranks first among the Fraunhofer Institutes. With the development of the audio coding method MPEG Layer-3, short MP3, Fraunhofer IIS has reached a world-leading position.
In close cooperation with our partners and clients we provide our research and develop services in the following areas: Digital radio broadcasting systems, audio and multimedia technology, design automation and integrated circuits, wired, wireless and optical networks, localization and navigation, high-speed camera systems, imaging systems and nanofocus X-ray technology, medical sensor solutions and communications technology in transport and logistics. |

Audio distribution system
POF is commonly used for connecting digital audio devices, but audio data can also be distributed throughout appartments. For this purpose speaker boxes with optical input are demonstrated. The appropriate audio channel for the location of the speaker box can be selected at each speaker and the corresponding signal is filtered out of the audio data stream.

TV transmission with POF
The transmission of multichannel CATV signals with standard POF is demonstrated. Optical transmitter and receiver modules have been developed that are capable to transmit carrier frequencies up to 472 MHz – well above the nominal bandwidth of POF.

WDM modules for POF and PCF
Wavelength division multiplexing (WDM) allows the transmisson of different protocols on the samer fiber as well as bidirectional transmission. The WDM modules with low insertion loss and good cross talk supression can be mass produced by injection moulding.

Hybrid optical & power outlet
We demonstrate an optical interface integrated into a standard wall socket with a passive optical backbone of low initial costs. A hybrid installation with the electricity network is possible. A star topology enables the connection of every socket to the desired data service (TV, voice, data).
