Transmitter and Receiver of the SFH series SFH757 SFH757V Type Ordering Code SFH757 SP000063871 SFH757V SP000063858

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. 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 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. 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 fiber. The force that is necessary to pull a jammed fiber 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 fiber and torque combination.

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.
