Product Bulletin OPF14X2/14X4 December 1996 High Speed Fiber Optic Transmitter Types OPF14X2/14X4 Series Features e Low Cost e High Speed e No Mounting Hardware Required e Wide Temperature Range @ 100% LED Burn-in (96 hours) e SMA or ST* Style Ports 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 um up to 200 um 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 increasing system reliability. The consistency of coupling varies by less than 5 dB from part to part which reduces the dynamic range requirements of the receiver. The high power (-16.5 dBm into 50/125 uum) OPF14X4 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 OPF14X2 (-11.5 dBm optical power) is ideal for 100/140 um fiber applications. ST is a registered trademark of AT&T.
