SFH250 and SFH250V Receiver with analog output for polymer optical fiber applications Data Sheet Description Features The SFH250 is a low-cost 650nm receiver for optical Fast Switching Time data transmission with polymer optical fiber. This Si- Sensitive in visible and near IR Range pin-photodiode works fine with the AVAGO transmitter High linearity SFH757. According to the intensity of the incident light the SFH250 generates an analog photocurrent. In typical 2.2mm aperture holds standard 980/1000/2200 um applications the SFH250 is operated in reverse-biasing plastic fiber and is installed in series with a resistor, where the voltage No fiber stripping required tapping is taken. By increasing the reverse voltage the Molded microlens for efficient coupling switching times decrease and the SFH250 can be used for transmission speeds up to 100MBd. Plastic Direct Fiber Connector housing Components of the SFH series are optimized for easy (V-housing) coupling. No fiber stripping is required, only the cut fiber Locking screw attached to the connector has to be inserted into the selected SFH component. Interference-free transmission by the light-tight SFH250 housing Transmitter and receiver can be positioned flexibly The transparent plastic package has an aperture where a 2.2mm fiber end can be inserted. This very easy coupling No cross talk method is extremely cost-effective.

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).
