OPTEK reserves the right to make changes at any time in order to improve design and to supply the best product possible.
Applications
♦ Industrial Ethernet equipment
♦ Copper-to-fiber media conversion
♦ Intra-system fiber optic links
♦ Video surveillance systems
OPF520
• Low Cost plastic cap package
• Designed to self align in the bore of standard fiber optic
receptacles
• Press fit simplifies installation
• Optimized for fiber optic applications using 50 to 200 mi-
cron fiber
The OPF520 fiber optic receiver is a high performance device packaged for data communications links. As such, it is designed
to work with fiber core diameters from 50µm to 200µm and over a broad input power range. The construction contains a mono-
lithic photo-IC comprised of a photodiode, biasing network, DC amplifier and an open collector output transistor. The output
circuitry makes this device compatible with TTL and CMOS logic.
This receiver is designed to operate from a single 5V supply. It is essential that a bypass capacitor be connected from VCC to
GND in order to ensure the best possible operation.
