SFH250 and SFH250V
Receiver with analog output
for polymer optical fiber applications
Data Sheet
Description
The SFH250 is a low-cost 650nm receiver for optical
data transmission with polymer optical fiber. This Si-
pin-photodiode works fine with the AVAGO transmitter
SFH757. According to the intensity of the incident light
the SFH250 generates an analog photocurrent. In typical
applications the SFH250 is operated in reverse-biasing
and is installed in series with a resistor, where the voltage
tapping is taken. By increasing the reverse voltage the
switching times decrease and the SFH250 can be used for
transmission speeds up to 100MBd.
Components of the SFH series are optimized for easy
coupling. No fiber stripping is required, only the cut fiber
has to be inserted into the selected SFH component.
SFH250
The transparent plastic package has an aperture where a
2.2mm fiber end can be inserted. This very easy coupling
method is extremely cost-effective.
SFH250V
The V-housing allows easy coupling of unconnectorized
2.2mm polymer optical fiber by means of an axial locking
screw.
