Media converter drives visible red light over POF

Firecomms has developed a reference design that enables integrated media converters to drive 1394 S800 signals using visible red light over plastic optical fiber (POF) home networks.

Supporting data rates of up to 1Gbit/s, the media converters enable applications such as the transfer of S800 video over 1394. Fitted with OptoLock, a plugless interconnect that allows for quick connection of bare POF, the media converters accept IEEE 1394 a/b electrical signals from any standard-compliant 1394 device over a nine-pin bilingual copper port. The signal is converted and repeated optically over POF. The repeated optical signal is received by a POF port integrated in a device, or an identical converter unit, which converts the optical signal back to electrical output at its copper port.

Through the use of a 1394b PHY IC, the copper port is compatible with IEEE 1394-1995, 1394a-2000 and 1394b-2002 standards, making the converter suitable for HANA (High-Definition Audio-Video Network Alliance) 1394-enabled home networking products.

The media converter reference designs are based on Firecomms' high-speed visible wavelength VCSEL technology, which is aimed at high-speed optical links over POF for consumer electronic applications.
