CatalogFilm_12601. 12/20/01 4:30 PM Page 41 Plastic Fiber Optic Super-Bright LED IF-E97 DESCRIPTION The IF-E97 is a high-optical-output, 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 ensure efficient optical coupling into standard 1000 µm core plastic fiber cable.

The IF-E97 can achieve data rates of 1 Mbps when used with an IF-D96 photologic detector. The visible red light has low attenuation in PMMA plastic fiber and aids in troubleshooting installations. The drive circuit design is simpler than required for laser diodes, making the IF-E97 the lowest cost selection for a variety of analog and digital applications requiring maximum operating distance.

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. FIGURE 2. Typical spectral output versus wavelength. PACKAGE IDENTIFICATION: Blue housing w/ Red dot • PIN 1.
