Plastic Fiber Optic Phototransistor
IF-D92
DESCRIPTION
The IF-D92 is a high-sensitivity phototransistor detector housed in a “connectorless” 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 into standard 1000 µm core plastic fiber cable.

The IF-D92 is suitable for digital data links at rates up to 25 kbps. Analog bandwidths 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.

1. Cut off the ends of the optical fiber with a singleedge razor blade or sharp knife. Try to obtain a
precise 90-degree angle (square).
2. Insert the fiber through the locking nut and into the
connector until the core tip seats against the internal
micro-lens.
3. Screw the connector locking nut down to a snug fit,
locking the fiber in place.
