The IF-E91A and IF-E91B are high-output medium-speed infrared LEDs in a
“connector-less” style plastic fiber optic package. The output spectrum peaks
at 950 nm for the IF-E91A and 880 nm for the IF-E91B. The device package
features an internal micro-lens, and a precision-molded PBT housing ensures
efficient optical coupling into standard 1000 µm plastic fiber cable.
A
The high output and fast transition times of the IF-E91A and IF-E91B make
them suitable for low-cost analog and digital data links. Used with an IF-D96
photologic detector, the IF-E91A and IF-E91B can achieve data rates of 500
Kbps and 1 Mbps respectively at link distances up to 7 m. The drive circuit
design is simpler than required for laser diodes, making the IF-E91A and IF-E91B
excellent low-cost alternatives in a variety of analog and digital applications.
