Data link for IP telephones.

Fraunhofer IPMS develops solutions for optical data communication to network telephones.


IP phones, telephones working over internet protocol, have almost completely replaced analog and ISDN devices. These devices are usually connected through CAT5 cables to a router or switch to data network and often receive operating power via Ethernet (Power over Ethernet). However, in some areas it is not possible to use cables or radio-based wireless technologies. Therefore, optical data links can replace cables and other data links. Using Li-Fi as an optical data transmission technology interference-free and secure data links can be established.
