IF-E99B

IF E99B 156 Mbps Plastic Fiber Optic Red LED 4/2/12 Description 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. Application Highlights 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.
