Fiber Optic Receiver
OPF2412, OPF2412T
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
OPF2412 Family
• Up to 5Mbps operation
• 850nm wavelength
• ST® style port
• CMOS and TTL compatible
• Wave solderable
• Wide temperature range
The OPF2412 family is a low cost digital output fiber optic receiver. The lensed optical system keeps the receiver response
consistent for all fiber sizes which makes it idea for use on fibers as small as 50/125µm. T he design incorporates a monolithic
photo-IC comprised of a photodetector and DC amplifier driving an open collector output Schottky transistor. The output makes
the OPF2412 compatible with TTL and CMOS logic. T he receiver is desi gned to operate from a single +5 V supply. A bypass
capacitor (0.1µF ceramic) should be connected from VCC to GND of the receiver.
