156 Mbps Plastic Fiber Optic Red LED IF E99B
De s c r i p t i o n
The IF-E99B is a very high-speed red LED housed in a “connector-less” style plastic fiber
optic package. The output spectrum of the IF-E99B is produced by a GaAIAs die that peaks
at a wavelength of 650 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 ensures efficient optical coupling with standard 1000 µm core plastic
fiber cable.
Ap p l i c A t i o n Hi g H l i g H t s
The fast transition times of the IF-E99B make it suitable for high-speed digital data links.
Link distances in excess of 75 meters at data rates of 156 Mbps are possible using standard
1000 µm core plastic fiber and an IF-D98 photologic detector. The wide analog bandwidth
permits direct modulation at RF frequencies exceeding 70MHz. Drive circuit design for the
IF-E99B requires good RF and digital design techniques, but is much simpler than required
for laser diodes, making it a good low-cost solution in a variety of high frequency POF
analog and digital applications.

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.
NOTE: To avoid degraded device life due to package stress, do not bend or form leads outside the orientation shown on drawing.
