The IF-D92 is a high-sensitivity NPN phototransistor detector housed in a
“connector-less” style plastic fiber optic package. Optical response of the
IF-D92 extends from 400 to 1100 nm, making it compatible with a wide range
of visible and near-infrared LEDs and laser diode sources. This includes 650 nm
visible red LEDs used for optimum transmission in PMMA plastic optic fiber.
The detector package features an internal micro-lens and a precision-molded
PBT housing to ensure efficient optical coupling with standard 1000 µm core
plastic fiber cable.

The IF-D92 is suitable for digital data links at rates up to 25 kbps. Analog band-
widths greater than 15 kHz are possible making the IF-D92 usable for high
frequency audio transmission. Phototransistor operation provides high internal
gain – reducing the amount of post-amplification required in many circuits. The
integrated design of the IF-D92 makes it a simple, cost-effective solution in a
variety of analog and digital applications.
