1 AFBR-5905Z/5905AZ ATM Multimde Fiber Transceivers in 2 x 5 Package Style Data Sheet Data Sheet Descriptin The AFBR-5905Z family f transceivers frm Avag prvide the system designer with prducts t implement a range f slutins fr multimde fiber SONET OC-3 (SDH STM-1) physical layers fr ATM and ther services. These transceivers are all supplied in the new industry standard 2 x 5 DIP style with a MT-RJ fiber cnnectr interface. ATM 2 km Backbne Links The AFBR-5905Z is a 1300 nm prduct with ptical perfrmance cmpliant with the SONET STS-3c (OC-3) Physical Layer Interface Specificatin. This physical layer is defined in the ATM Frum User-Netwrk Interface (UNI) Specificatin Versin 3.0. This dcument references the ANSI T1E1.2 specificatin fr the details f the interface fr 2 km multimde fiber backbne links. The ATM 100 Mb/s- 125 MBd Physical Layer interface is best implemented with the AFBR- 5903Z family f FDDI Transceivers which are specified fr use in this 4B/5B encded physical layer per the FDDI PMD standard. Transmitter Sectins The transmitter sectin f the AFBR-5905Z utilizes a 1300 nm InGaAsP LED. This LED is packaged in the ptical subassembly prtin f the transmitter sectin. It is driven by a custm silicn IC which cnverts differential PECL lgic signals, ECL referenced (shifted) t a +3.3 V supply, int an analg LED drive current.

2 Receiver Sectins The receiver sectin f the AFBR-5905Z utilizes an InGaAs PIN phtdide cupled t a custm silicn transimpedance preamplifier IC. It is packaged in the ptical subassembly prtin f the receiver. This PIN/preamplifier cmbinatin is cupled t a custm quantizer IC which prvides the final pulse shaping fr the lgic utput and the Signal Detect functin. The Data utput is differential. The Signal Detect utput is singleended. Bth Data and Signal Detect utputs are PECL cmpatible, ECL referenced (shifted) t a 3.3 V pwer supply. The receiver utputs, Data Out and Data Out Bar, are squelched at Signal Detect Deassert. That is, when the light input pwer decreases t a typical -38 dbm r less, the Signal Detect Deasserts, i.e. the Signal Detect utput ges t a PECL lw state. This frces the receiver utputs, Data Out and Data Out Bar t g t steady PECL levels High and Lw respectively. Package The verall package cncept fr the Avag transceiver cnsists f three basic elements; the tw ptical subassemblies, an electrical subassembly, and the husing as illustrated in the blck diagram in Figure 1. The package utline drawing and pin ut are shwn in Figures 2 and 3. The details f this package utline and pin ut are cmpliant with the multisurce definitin f the SUPPLY 2 x 5 DIP. The lw prfile f the Avag transceiver design cmplies with the maximum height allwed fr the MT-RJ cnnectr ver the entire length f the package. The ptical subassemblies utilize a high-vlume assembly prcess tgether with lw-cst lens elements which result in a cst-effective building blck. The electrical subassembly cnsists f a high vlume multilayer printed circuit bard n which the IC and varius surface-munted passive circuit elements are attached. The receiver sectin includes an internal shield fr the electrical and ptical subassemblies t ensure high immunity t external EMI fields. The uter husing is electrically cnductive and is at reciever signal grund ptential. The MT-RJ prts is mlded f filled nncnductive plastic t prvide mechanical strength and electrical islatin. The slder psts f the Avag design are islated frm the internal circuit f the transceiver. The transceiver is attached t a printed circuit bard with the ten signal pins and the tw slder psts which exit the bttm f the husing. The tw slder psts prvide the primary mechanical strength t withstand the lads impsed n the transceiver by mating with the MT-RJ cnnectred fiber cables. fiber cables.

5 Applicatin Infrmatin The Applicatins Engineering grup is available t assist yu with the technical understanding and design tradeffs assciated with these transceivers. Yu can cntact them thrugh yur Avag sales representative. The fllwing infrmatin is prvided t answer sme f the mst cmmn questins abut the use f these parts. Transceiver Optical Pwer Budget versus Link Length Optical Pwer Budget (OPB) is the available ptical pwer fr a fiber ptic link t accmmdate fiber cable lsses plus lsses due t in-line cnnectrs, splices, ptical switches, and t prvide margin fr link aging and unplanned lsses due t cable plant recnfiguratin r repair. Figure 4 illustrates the predicted OPB assciated with the transceiver specified in this data sheet at the Beginning f Life (BOL). These curves represent the attenuatin and chrmatic plus mdal dispersin lsses assciated with the 62.5/125 µm and 50/ 125 µm fiber cables nly. The area under the curves represents the remaining OPB at any link length, which is available fr vercming nnfiber cable related lsses. Avag LED technlgy has prduced 1300 nm LED devices with lwer aging characteristics than nrmally assciated with these technlgies in the industry. The industry cnventin is 1.5 db aging fr 1300 nm LEDs. The 1300 nm Avag LEDs are specified t experience less than 1 db f aging ver nrmal cmmercial equipment missin life perids. Cntact yur Avag sales representative fr additinal details. Figure 4 was generated fr the 1300 nm transceivers with a Avag fiber ptic link mdel cntaining the current industry cnventins fr fiber cable specificatins and the draft ANSI T1E1.2. These ptical parameters are reflected in the guaranteed perfrmance f the transceiver specificatins in this data sheet. This same mdel has been used extensively in the ANSI and IEEE cmmittees, including the ANSI T1E1.2 cmmittee, t establish the ptical perfrmance requirements fr varius fiber ptic interface standards.

6 Transceiver Signaling Operating Rate Range and BER Perfrmance Fr purpses f definitin, the symbl (Baud) rate, als called signaling rate, is the reciprcal f the symbl time. Data rate (bits/sec) is the symbl rate divided by the encding factr used t encde the data (symbls/bit). When used in 155 Mb/s SONET OC-3 applicatins the perfrmance f the 1300 nm transceivers, AFBR-5905 is guaranteed t the full cnditins listed in prduct specificatin tables. The transceivers may be used fr ther applicatins at signaling rates different than 155 Mb/s with sme variatin in the link ptical pwer budget. Figure 5 gives an indicatin f the typical perfrmance f these prducts at different rates. These transceivers can als be used fr applicatins which require different Bit Errr Rate (BER) perfrmance. Figure 6 illustrates the typical trade-ff between link BER and the receivers input ptical pwer level. Transceiver Jitter Perfrmance The Avag 1300 nm transceivers are designed t perate per the system jitter allcatins stated in Table B1 f Annex B f the draft ANSI T1E1.2 Revisin 3 standard. The Avag 1300 nm transmitters will tlerate the wrst case input electrical jitter allwed in Annex B withut vilating the wrst case utput ptical jitter requirements. The Avag 1300 nm receivers will tlerate the wrst case input ptical jitter allwed in Annex B withut vilating the wrst case utput electrical jitter allwed. The jitter specificatins stated in the fllwing 1300 nm transceiver specificatin tables are derived frm the values in Table B1 f Annex B. They represent the wrst case jitter cntributin that the transceivers are allwed t make t the verall system jitter withut vilating the Annex B allcatin example. In practice, the typical cntributin f the Avag transceivers is well belw these maximum allwed amunts. Recmmended Handling Precautins Avag recmmends that nrmal static precautins be taken in the handling and assembly f these transceivers t prevent damage which may be induced by electrstatic discharge (ESD). The AFBR-5905Z series f transceivers meet MIL-STD- 883C Methd Class 2 prducts. Care shuld be used t avid shrting the receiver data r signal detect utputs directly t grund withut prper current limiting impedance. Slder and Wash Prcess Cmpatibility The transceivers are delivered with prtective prcess plugs inserted int the MT-RJ receptacle. This prcess plug prtects the ptical subassemblies during wave slder and aqueus wash prcessing and acts as a dust cver during shipping. These transceivers are cmpatible with either industry standard wave r hand slder prcesses.

13 Ntes: 1. This is the maximum vltage that can be applied acrss the Differential Transmitter Data Inputs t prevent damage t the input ESD prtectin circuit. 2. The utputs are terminated with 50 Ω cnnected t VCC -2 V. 3. The pwer supply current needed t perate the transmitter is prvided t differential ECL circuitry. This circuitry maintains a nearly cnstant current flw frm the pwer supply. Cnstant current peratin helps t prevent unwanted electrical nise frm being generated and cnducted r emitted t neighbring circuitry. 4. This value is measured with the utputs terminated int 50 Ω cnnected t VCC - 2 V and an Input Optical Pwer level f -14 dbm average. 5a. The pwer dissipatin f the transmitter is calculated as the sum f the prducts f supply vltage and current. 5b. The pwer dissipatin f the receiver is calculated as the sum f the prducts f supply vltage and currents, minus the sum f the prducts f the utput vltages and currents. 6. This value is measured with respect t VCC with the utput terminated int 50 Ω cnnected t VCC - 2 V. 7. The utput rise and fall times are measured between 20% and 80% levels with the utput cnnected t VCC -2 V thrugh 50 Ω. 8. These ptical pwer values are measured with the fllwing cnditins: The Beginning f Life (BOL) t the End f Life (EOL) ptical pwer degradatin is typically 1.5 db per the industry cnventin fr lng wavelength LEDs. The actual degradatin bserved in Avag s 1300 nm LED prducts is < 1 db, as specified in this data sheet. Over the specified perating vltage and temperature ranges. With 25 MBd (12.5 MHz square-wave), input signal. At the end f ne meter f nted ptical fiber with cladding mdes remved. The average pwer value can be cnverted t a peak pwer value by adding 3 db. Higher utput ptical pwer transmitters are available n special request. Please cnsult with yur lcal Avag sales representative fr further details. 9. The Extinctin Rati is a measure f the mdulatin depth f the ptical signal. The data 1 utput ptical pwer is cmpared t the data 0 peak utput ptical pwer and expressed in decibels. With the transmitter driven by a 25 MBd (12.5 MHz square-wave) input signal, the average ptical pwer is measured. The data 1 peak pwer is then calculated by adding 3 db t the measured average ptical pwer. The data 0 utput ptical pwer is fund by measuring the ptical pwer when the transmitter is driven by a lgic 0 input. The extinctin rati is the rati f the ptical pwer at the 1 level cmpared t the ptical pwer at the 0 level expressed in decibels. 10. The transmitter will prvide this lw level f Output Optical Pwer when driven by a lgic 0 input. This can be useful in link trubleshting. 11. The relatinship between Full Width Half Maximum and RMS values fr Spectral Width is derived frm the assumptin f a Gaussian shaped spectrum which results in a 2.35 X RMS = FWHM relatinship. 12. The ptical rise and fall times are measured frm 10% t 90% when the transmitter is driven by a 25 MBd (12.5 MHz square-wave) input signal. The ANSI T1E1.2 cmmittee has designated the pssibility f defining an eye pattern mask fr the transmitter ptical utput as an item fr further study. Avag will incrprate this requirement int the specificatins fr these prducts if it is defined. The HFBR prducts typically cmply with the template requirements f CCITT (nw ITU-T) G.957 Sectin 3.2.5, Figure 2 fr the STM-1 rate, excluding the ptical receiver filter nrmally assciated with single mde fiber measurements which is the likely surce fr the ANSI T1E1.2 cmmittee t fllw in this matter. 13. Systematic Jitter cntributed by the transmitter is defined as the cmbinatin f Duty Cycle Distrtin and Data Dependent Jitter. Systematic Jitter is measured at 50% threshld using a MBd (77.5 MHz square-wave), 27-1 psuedrandm data pattern input signal. 14. Randm Jitter cntributed by the transmitter is specified with a MBd (77.5 MHz square-wave) input signal. 15. This specificatin is intended t indicate the perfrmance f the receiver sectin f the transceiver when Input Optical Pwer signal characteristics are present per the fllwing definitins. The Input Optical Pwer dynamic range frm the minimum level (with a windw time-width) t the maximum level is the range ver which the receiver is guaranteed t prvide utput data with a Bit Errr Rate (BER) better than r equal t 1 x At the Beginning f Life (BOL) Over the specified perating temperature and vltage ranges Input is a MBd, PRBS data pattern with 72 1 s and 72 0 s inserted per the CCITT (nw ITU-T) recmmendatin G.958 Appendix I. Receiver data windw time-width is 1.23 ns r greater fr the clck recvery circuit t perate in. The actual test data windw time-width is set t simulate the effect f wrst case ptical input jitter based n the transmitter jitter values frm the specificatin tables. The test windw time-width is AFBR-5905Z 3.32 ns. Transmitter perating with a MBd, 77.5 MHz square-wave, input signal t simulate any crss-talk present between the transmitter and receiver sectins f the transceiver. 16. All cnditins f Nte 15 apply except that the measurement is made at the center f the symbl with n windw time-width. 17. Systematic Jitter cntributed by the receiver is defined as the cmbinatin f Duty Cycle Distrtin and Data Dependent Jitter. Systematic Jitter is measured at 50% threshld using a MBd (77.5 MHz square-wave), 27-1 psuedrandm data pattern input signal. 18. Randm Jitter cntributed by the receiver is specified with a MBd (77.5 MHz square-wave) input signal. 19. This value is measured during the transitin frm lw t high levels f input ptical pwer. 20. This value is measured during the transitin frm high t lw levels f input ptical pwer. At Signal Detect Deassert, the receiver utputs Data Out and Data Out Bar g t steady PECL levels High and Lw respectively. 21. The Signal Detect utput shall be asserted within 100 µs after a step increase f the Input Optical Pwer. 22. Signal detect utput shall be de-asserted within 350 µs after a step decrease in the Input Optical Pwer. At Signal Detect Deassert, the receiver utputs Data Out and Data Out Bar g t steady PECL levels High and Lw respectively. 23. The AFBR-5905Z transceiver cmplies with the requirements fr the trade-ffs between center wavelength, spectral width, and rise/ fall times shwn in Figure 11. This figure is derived frm the FDDI PMD standard (ISO/IEC : 1990 and ANSI X ) per the descriptin in ANSI T1E1.2 Revisin 3. The interpretatin f this figure is that values f Center Wavelength and Spectral Width must lie alng the apprpriate Optical Rise/ Fall Time curve.
