fea tures low cost high speed no mounting hardware required wide temperature range 100% led burn-in (96 hours) st* style port wave solderable de scrip tion 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 m up to 200 m 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 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 m 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 m fiber applications. ab so lute maxi mum rat ings (t a = 25 o c un less oth er wise noted) stor age tem pera ture . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -55 o c to +85 o c op er at ing tem pera ture . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -40 o c to +85 o c lead sol der ing tem pera ture . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 260 o c(10 sec) for ward in put cur rent . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . peak 200 ma . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . dc 100 ma re verse in put volt age . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1.8 v see me chani cal di men sions page 8-19 for me chani cal draw ings. avail able in panel mount st* pack age; add ?t? suf fix to part number. prod uct bul le tin opf1412/1414 de cem ber 1997 high speed fiber optic transmitter types opf1412/1414 se ries bot tom view pin func tion 1 n.c. 2 anode 3 cathode 4 n.c. 5 n.c. 6 anode 7 anode 8 n.c. op tek tech nol ogy, inc. 1215 w. crosby road car roll ton, texas 75006 (972) 323- 2200 fax (972)323- 2396 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. 8-4
