The IF-D91 is a high-speed photodiode detector housed in a “connector-less”
style plastic fiber optic package. Optical response of the IF-D91 extends from
400 to 1100 nm, making it compatible with a wide range of visible and near-
infrared LED and laser diode sources. This includes 650 nm visible red LEDs
used for optimum transmission in PMMA plastic optic fiber. The detector pack-
age 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 fast response times of the IF-D91 make it suitable for high-speed digital data
links. When used with an appropriate LED or laser diode source the IF-D91 is
capable of 100 Mbps data rates. The IF-D91 also can be used in analog video
links with bandwidths up to 70 MHz. The integrated design of the IF-D91
provides simple, cost-effective implementation in a variety of analog and digital
applications.
