HFBR-1312TZ transmitter hfbr-2316tz receiver 1300 nm fiber optic transmitter and receiver data sheet description the HFBR-1312TZ transmitter and hfbr-2316tz receiver are designed to provide the most cost-efective 1300 nm fber optic links for a wide variety of data communication applica tions from low-speed distance extenders up to sonet oc-3 signal rates. pinouts identical to avago hfbr- 0400z series allow designers to easily upgrade their 820 nm links for farther distance. the transmit ter and receiver are compatible with two popular optical fber sizes: 50/125 m and 62.5/125 m diameter. this allows fex - ibility in choosing a fber size. the 1300 nm wave length is in the lower dispersion and attenua tion region of fber, and provides longer distance capabilities than 820 nm led technology. typi cal distance capabilities are 2 km at 125 mbd and 5 km at 32 mbd. transmitter the HFBR-1312TZ fber optic transmitter contains a 1300 nm ingaasp light emitting diode capable of efciently launching optical power into 50/125 m and 62.5/125 m diameter fber. converting the interface circuit from a hfbr-14xxz 820 nm transmitter to the HFBR-1312TZ requires only the removal of a few passive components. *st is a registered trademark of at&t lightguide cable connectors features ? rohs-compliant ? low cost fber optic link ? signal rates over 155 megabaud ? 1300 nm wavelength ? link distances over 5 km ? dual-in-line package panel-mountable st* and sc connector receptacles ? auto-insertable and wave-solderable ? specifed with 62.5/125 m and 50/125 m fber ? compatible with hfbr-0400z series ? receiver also specifed for sm cable spec (9/125 m) applications ? desktop links for high speed lans ? distance extension links ? telecom switch systems ? taxlchip ? compatible
2 HFBR-1312TZ transmitter hfbr-2316tz receiver mechanical dimensions receiver the hfbr-2316tz receiver con tains an ingaas pin photo- diode and a low-noise transimpedance preamplifer that operate in the 1300 nm wavelength region. the hfbr- 2316tz receives an optical signal and converts it to an an - alog voltage. the bufered output is an emitter-follower, with frequency response from dc to typically 125 mhz. low-cost external compo nents can be used to convert the analog output to logic compatible signal levels for a variety of data formats and data rates. the hfbr-2316tz is pin compatible with hfbr-24x6z receivers and can be used to extend the distance of an existing application by sub sti-tuting the hfbr-2316tz for the hfbr-2416z. package information the transmitter and receiver are housed in a dual-in-line package made of high strength, heat resistant, chem - ically resistant, and ul v - 0 fame retardant plastic. the package is auto-insertable and wave solderable for high volume production applications. note: the t in the product numbers indicates a threaded st connector (panel mountable), for both transmitter and receiver. handling and design information when soldering, it is advisable to leave the protective cap on the unit to keep the optics clean. good system per - formance requires clean port optics and cable ferrules to avoid obstructing the optical path. clean com pressed air is often sufcient to remove particles of dirt; methanol on a cotton swab also works well. 2, 6 anode 3 cathode pin function 1 2 3 4 5 6 7* 8 n.c. anode cathode n.c. n.c. anode n.c. n.c. pin no. 1 indicator bottom view * pin 7 is electrically isolated from pins 1, 4, 5, and 8, but is connected to the header. pins 1, 4, 5, and 8 are isolated from the internal circuitry, but are electrically connected to each other. 1 4 3 2 8 5 6 7 pin no. 1 indicator bottom view 6 2 3, 7 v cc analog signal v ee pin function 1 2 3* 4 5 6 7* 8 * pins 3 and 7 are electrically connected to the header. pins 1, 4, 5, and 8 are isolated from the internal circuitry, but are electrically connected to each other. n.c. signal v ee n.c. n.c. v cc v ee n.c. 1 4 3 2 8 5 6 7 8 1 3 5 2 4 6 7 pin no. 1 indicator pins 1,4,5,8 0.51 x 0.38 (0.020 x 0.015) pins 2,3,6,7 0.46 (0.018) dia 12.6 (0.495) 3.81 (0.150) 2.54 (0.100) 3/8-32 unef-2a yyww hfbr-x31xtz 12.6 (0.495) 5.05 (0.199) 7.05 (0.278) 29.8 (1.174) part number date code dia. 6.30 (0.248) 7.62 (0.300) 3.60 (0.140) 8.31 (0.327) 10.20 (0.400) 5.10 (0.202) 2.54 (0.100) 1.27 (0.050)
