1 HFBR-8 Series HFBR-8 Transmitter HFBR-8 Receiver Megabaud Versatile Link Fiber Optic Transmitter and Receiver for mm POF and µm HCS Data Sheet Description The HFBR-8 Series consists of a fiber-optic transmitter and receiver operating at a 6 nm wavelength (red). The HFBR-8 transmitter is an LED in a low cost plastic housing designed to efficiently couple power into µm diameter HCS and mm diameter POF. The HFBR-8 receiver incorporates a PIN detector and digital output IC compatible with CMOS and TTL logic families. HFBR-8 links operate from DC to MBd at distances up to meters with mm POF and up to meters with µm HCS. No minimum link distances are required when using recommended circuits, simplifying design. Versatile Link components can be interlocked (Nplexed 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 field-terminated. A single transmitter drive current for POF and HCS allows both fibers to be used with a single design. Features Data transmission at signal rates of dc to MBd Up to meters distances with mm Plastic Optical Fiber (POF) Up to meters distances with µm Hard Clad Silica (HCS ) Wide dynamic range receiver allows operation from zero to maximum link distance with a single transmitter drive current Link distances specified for variations in temperature, power supply, and fiber attenuation DC coupled receiver with CMOS/TTL output for easy designs: no data encoding or digitizing circuitry required Pulse width distortion controlled to limit distortion from low duty cycle or burst mode data High noise immunity Compatible with Avago s Versatile Link family of connectors, for easy termination of fiber Applications Industrial control and factory automation Serial field buses Intra-system links; Board-to-Board, Rack-to-Rack Extension of RS-, RS-8 Elimination of ground loops High voltage isolation Reduces voltage transient susceptibility HCS is a registered trademark of SpecTran Corporation. CAUTION:. It is advised that normal static precautions be taken in handling and assembly of these components to prevent damage and/or degradation which may be induced by ESD.

3 HFBR-8 Transmitter The HFBR-8 transmitter incorporates a 6 nm LED in a light gray, nonconductive plastic housing. The high light output power enables the use of both plastic optical fiber (POF) and Hard Clad Silica (HCS) fiber. This transmitter can be operated up to MBd using a simple driver circuit. The HFBR-8 is compatible with all Versatile Link connectors.

5 HFBR-8 Receiver The HFBR-8 receiver consists of a silicon PIN photodiode and digitizing IC to produce a logic compatible output. The IC includes a unique circuit to correct the pulse width distortion of the first bit after a long idle period. This enables operation from DC to MBd with low PWD for arbitrary data patterns. The receiver output is a push-pull stage compatible with TTL and CMOS logic. The receiver housing is a dark, conductive plastic, compatible with all Versatile Link connectors.
