The HFBR-0508Z Series consists of a fi ber-optic transmitter and receiver operating at a 650 nm wavelength (red). The HFBR-1528Z transmitter is an LED in a low cost plastic housing designed to effi ciently couple power into 200 μm diameter Hard Clad Silica (HCS) and 1 mm diameter Plastic optical fi ber (POF). The HFBR-2528Z receiver incor porates a PIN detec tor and digital output IC compat ible with CMOS and TTL logic families. HFBR-0508Z links operate from DC to 10 MBd at distances up to 50 meters with 1 mm POF and up to 500 meters with 200 μm HCS. No minimum link distances are required when using recom mended circuits, simplifying design. Versatile Link components can be interlocked (N-plexed together) to minimize space and to provide dual connections with the duplex connectors. Up to eight packages can be interlocked and inserted into a printed circuit board. POF and HCS are available in pre-connectored lengths or can be easily fi eld-terminated. A single transmitter drive current for POF and HCS allows both fi bers to be used with a single design.
