IF-E96
5/2/06
The IF-E96 is a low-cost, high-speed, visible red LED housed in a “connector-
less” style plastic fiber optic package. The output spectrum is produced by a
GaAlAs die which peaks at 660 nm, one of the optimal transmission windows
of PMMA plastic optical fiber. The device package features an internal micro-
lens and a precision-molded PBT housing to maximize optical coupling into
standard 1000 µm core plastic fiber cable.

The performance/price ratio of the IF-E96 is particularly attractive for high vol-
ume design applications. The visible red output has low attenuation in PMMA
plastic fiber and aids in troubleshooting installations. When used with an IF-D96
photologic detector the IF-E96 can achieve data rates of 5 Mbps. Fast transition
times and low attenuation make the IF-E96 an excellent device selection for
low cost analog and digital data links up to 75 meters.

1. Cut off the ends of the optical fiber with a single-
edge 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.
