Description: The OPF2418 family is a low cost solution for high speed fiber optic communications designs. The internal lensing of this receiver’s design allows optimal response for fiber sizes of 100µm and below. The receiver is comprised of a high speed, low noise, photodiode coupled to a transimpedance amplifier (TIA). The photodiode/TIA combination produces an output voltage that is proportional to the input light amplitude. This hybrid approach solves many of the problems of high speed data link designs by placing the photodiode close to the TIA. The amplification of the TIA makes the output much less susceptible to EMI. The output of the OPF2418 is an analog, low impedance, emitter follower voltage source. Subsequent circuitry can be utilized to convert the analog voltage to ECL/TTL for digital data rates up to 155 Mbps. The OPF2418 is available with either standard or threaded panel mount STÒ receptacles. The threaded version is also available in conductive plastic. Applications: Industrial Ethernet equipment Copper-to-fiber media conversion Intra-system fiber optic links Video surveillance systems Features: Up to 194 Mbps operation 850nm wavelength ST style port Wave solderable Wide temperature range PIN FUNCTION
