SFH757 E9386 SP000234857
Description
The SFH757 is a low-cost transmitter for simple optical
data transmission with polymer optical ber. This very
robust 650nm LED can be used for speeds up to 100MBd.
The transparent plastic package has an aperture where
the the 2.2mm ber-end can be inserted and xed with
glue. This easy coupling method is extremely cost-
eective.

Notes:
1. The output power coupled into plastic ber is measured with a large area detector at the end of a short length of ber (about 30 cm). Enhanced
losses of a POF on the rst meters due to leaky modes have to be taken into account when calculating the power budget for a long POF.
