| Product Bulletin OPF1412/1414 December 1997 High Speed Fiber Optic Transmitter Types OPF1412/1414 Series Features *Low Cost *High Speed *No Mounting Hardware Required *Wide Temperature Range *100% LED Burn-In (96 hours) *ST* Style Port *Wave Solderable Description The OPF14XX series fiber optic transmitters contain a high speed 840 nm GaAlAs LED. This LED in conjunction with the package lensing is designed to efficiently couple light into optical fibers ranging in size from 50/125 m up to 200 m PCS. These devices were designed to work together with the Optek OPF24XX series receivers to make-up a complete high speed fiber optic link.

The high coupling efficiency of the LED and lensing allows the devices to be used at low current drive levels thus decreasing the power consumption and Bottom View increasing system reliability. The consistency of coupling varies by less than 5 dB from part to part which See Mechanical Dimensions page 8-19 for Mechanical Drawings. reduces the dynamic range Available in Panel Mount ST* package; add "T" suffix to part number. requirements of the receiver. The high power (-16.5 dBm into 50/125 m) OPF1414 was designed for small fiber applications or where there are large fixed losses such as in systems that contain star couplers or in line connectors. The OPF1412 (-11.5 dBm optical power) is ideal for 100/140 m fiber applications. Optek Technology, Inc. This component is susceptible to damage from electrostatic discharge (ESD). Normal static precautions should be taken in handling and assembly of this component to prevent ESD damage or degradation. 1215 W.
