SFH757 and SFH757V Transmitter for Polymer Optical Fiber Applications Data Sheet Description Features The SFH757 is a low-cost transmitter diode for optical High speed transmitter for up to 100MBd applications data transmission with polymer optical fiber. Its InGaAlP (with peaking circuits) LED chip provides enhanced resistance to humidity and 2.2mm aperture holds standard 980/1000/2200m is designed to emit light at 650 nm. The robust SFH757 plastic fibers can be used for speeds up to 100 MBd and complements No fiber stripping required the Avago SFH250 photodiode receiver and SFH551/1-1 integrated photo detector receiver. Molded microlens for efficient coupling The SFH series is optimized for easy coupling. No fiber stripping is required just insert the cut fiber into the Plastic Direct Fiber Connector housing selected SFH component. (V-housing) Locking screw attached to the connector SFH757 Interference-free transmission by the light-tight The transparent plastic package has an aperture where a housing 2.2 mm fiber end can be inserted. This very easy coupling method is extremely cost-effective. Transmitter and receiver can be positioned flexibly No cross talk SFH757V Auto insertable and wave solderable The V-housing allows easy coupling of unconnectorized Supplied in tubes 2.2 mm polymer optical fiber with an axial locking screw.

This is an approximate value that is very on the housing. dependent on the fiber and torque combination. Package V-housing mounting pins SFH V-series components have two pins that are electri- cally isolated from the inner circuit. The pins are only designed for mounting the V-housing to the PCB surface. This helps increase stability, which is needed during fixing the fiber end by the axial locking screw. The retention force between the soldered mounting pins Package V-housing mounting pins Package V-housing axial locking screw and the V-housing of the SFH component is about 20 N (with a vertical exertion of force). This is an approximate value. 2 3.5 0.5 0.6 4.625 2.275 4.8 8.8 2.54
