SFH250 and SFH250V

Receiver with analog output

for polymer optical ber applications

Data Sheet

Description

The SFH250 is a low-cost 650nm receiver for optical

data transmission with polymer optical ber. This Si-

pin-photodiode works ne 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 ber stripping is required, only the cut ber

has to be inserted into the selected SFH component.

SFH250

The transparent plastic package has an aperture where a

2.2mm ber end can be inserted. This very easy coupling

method is extremely cost-eective.

SFH250V

The V-housing allows easy coupling of unconnectorized

2.2mm polymer optical ber by means of an axial locking

screw.

Package V-housing Color

SFH V-series components are color coded just like other

Avago ber optic components. The SFH757V transmitter

has a white colored housing; the SFH250V and SFH551/1-

1V receiver components have a black colored housing.

This prevents mistakes while making connections.

Product designation and date of manufacture are printed

on the housing.

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

xing the ber end by the axial locking screw.

The retention force between the soldered mounting pins

and the V-housing of the SFH component is about 20 N

(with a vertical exertion of force). This is an approximate

value.

Package V-housing axial locking screw

Components of the SFH V-series are equipped with an

axial locking screw for easy coupling to the unconnec-

torized 2.2 mm polymer optical ber. The force that is

necessary to pull a jammed ber out of the V-housing is

typically 50 N (with a torque of 15 cNm for tightening the

locking screw). This is an approximate value that is very

dependent on the ber and torque combination.
