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
LED chip provides enhanced resistance to humidity and
is designed to emit light at 650 nm. The robust SFH757
can be used for speeds up to 100 MBd and complements
the Avago SFH250 photodiode receiver and SFH551/1-1
integrated photo detector receiver.
(with peaking circuits)
• 2.2mm aperture holds standard 980/1000/2200µm
plastic fibers
• No fiber stripping required
• 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
2.2 mm fiber end can be inserted. This very easy coupling
method is extremely cost-effective.

Package V-housing Color
Package V-housing axial locking screw
SFH V-series components are color coded just like other
Avago fiber optic components. The SFH757V transmitter
has a white colored housing; the SFH250V and SFH551/1-
1V receiver components have a black colored housing.
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 fiber. The force that is
necessary to pull a jammed fiber out of the V-housing is
This prevents mistakes while making connections. typically 50 N (with a torque of 15 cNm for tightening the
Product designation and date of manufacture are printed
on the housing.
locking screw). This is an approximate value that is very
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
and the V-housing of the SFH component is about 20 N
(with a vertical exertion of force). This is an approximate
value.

Notes:
1. Given switching time values can be reduced by suitable driver circuits. Also an increase of LED-Current leads to a reduction of the switching times.
2. Measured at 25°C
3. The optical output power coupled into a polymere optical fiber (NA=0.5) is measured with a large area detector at the end of a short fiber (about 1m).
4. Driver circuit for the characterization process: see Figure 2 (Vcc=5.0V; installed R_ILED = 100Ohm)
