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
OPF472
• High speed, low capacitance
• Popular ST® style receptacle
• Pre-tested with fiber to assure performance
• Component pre-mounted and ready to use
• 35MHz operation minimum
The OPF472 is a low noise sil icon PIN photodiode mounted in a lo w cost package for fiber optic applications. It offers fast re-
sponse at moderate bias and is compatible with LED and laser diode sources in the 800-1000 nm wavelength region. Low
capacitance improves signal to noise performance in typical short haul LA N applications.
The OPF472 is desig ned to be compatible with multimode optical fibers from 50/125 to 200/300 microns.
