130 technologies in the industry. the industry convention is 3 db aging for 800 nm and 1.5 db aging for 1300 nm leds. the hp 1300 nm leds will experience less than 1 db of aging over normal com- mercial equipment mission life periods. contact your hewlett- packard sales representative for additional details. figure 4 was generated with a hewlett-packard fiber optic link model containing the current industry conventions for fiber cable specifications and the fddi pmd and lcf-pmd optical parameters. these parameters are reflected in the guaranteed performance of the transceiver specifications in this data sheet. this same model has been used extensively in the ansi and ieee committees, including the ansi x3t9.5 committee, to establish the optical performance require- ments for various fiber optic interface standards. the cable parameters used come from the iso/iec jtc1/sc 25/wg3 generic cabling for customer premises per dis 11801 docu- mounted passive circuit elements are attached. the package includes internal shields for the electrical and optical subassemblies to ensure low emi emissions and high immunity to external emi fields. the outer housing including the duplex sc connector receptacle or the duplex st ports is molded of filled non-conductive plastic to provide mechanical strength and electrical isolation. the solder posts of the hewlett-packard design are isolated from the circuit design of the transceiver and do not require connection to a ground plane on the circuit board. the transceiver is attached to a printed circuit board with the nine signal pins and the two solder posts which exit the bottom of the housing. the two solder posts provide the primary mechanical strength to withstand the loads imposed on the trans- ceiver by mating with duplex or simplex sc or st connectored fiber cables. application information the applications engineering group in the hewlett-packard optical communication division is available to assist you with the technical understanding and design trade-offs associated with these transceivers. you can contact them through your hewlett-packard sales representative. the following information is provided to answer some of the most common questions about the use of these parts. transceiver optical power budget versus link length optical power budget (opb) is the available optical power for a fiber optic link to accommodate fiber cable losses plus losses due to in-line connectors, splices, optical switches, and to provide margin for link aging and unplanned losses due to cable plant reconfiguration or repair. figure 4 illustrates the predicted opb associated with the three transceiver series specified in this data sheet at the beginning of life (bol). these curves represent the attenuation and chromatic plus modal dispersion losses associated with the 62.5/ 125 m m and 50/125 m m fiber cables only. the area under the curves represents the remaining opb at any link length, which is available for overcoming non- fiber cable related losses. hewlett-packard led technology has produced 800 nm led and 1300 nm led devices with lower aging characteristics than normally associated with these figure 4. optical power budget at bol versus fiber optic cable length. optical power budget (db) 4.0 14 0 fiber optic cable length (km) 0.5 1.5 2.0 2.5 12 10 8 6 4 3.5 2 1.0 3.0 0.15 HFBR-5103, 62.5/125 ?

132 fddi pmd and lcf-pmd standards without violating the worst case output electrical jitter allowed in the tables e1 of the annexes e. the jitter specifications stated in the following 1300 nm transceiver specification tables are derived from the values in tables e1 of annexes e. they represent the worst case jitter contribution that the transceivers are allowed to make to the overall system jitter without violating the annex e allocation example. in practice the typical contribution of the hp transceivers is well below these maximum allowed amounts. recommended handling precautions hewlett-packard recommends that normal static precautions be taken in the handling and assembly of these transceivers to prevent damage which may be induced by electrostatic discharge (esd). the hfbr- 5100 series of transceivers meet mil-std-883c method 3015.4 class 2 products. care should be used to avoid shorting the receiver data or signal detect outputs directly to ground without proper current limiting impedance. solder and wash process compatibility the transceivers are delivered with protective process plugs inserted into the duplex sc or duplex st connector receptacle. this process plug protects the optical subassemblies during wave solder and aqueous wash processing and acts as a dust cover during shipping. these transceivers are compat- ible with either industry standard wave or hand solder processes. shipping container the transceiver is packaged in a shipping container designed to protect it from mechanical and esd damage during shipment or storage. board layout - decoupling circuit and ground planes it is important to take care in the layout of your circuit board to achieve optimum performance from these transceivers. figure 7 provides a good example of a schematic for a power supply decoupling circuit that works well with these parts. it is further recommended that a contiguous figure 7. recommended decoupling and termination circuits no internal connection no internal connection hfbr-510x top view v ee rd rd sd v cc v cc td td v ee 123456789 c1 c2 l1 l2 r2 r3 r1 r4 c5 c3 c4 r9 r10 v cc filter at v cc pins transceiver r5 r7 r6 r8 c6 rd rd sd v cc td td termination at phy device inputs notes: the split-load terminations for ecl signals need to be located at the input of devices receiving those ecl signals. recommend 4-layer printed circuit board with 50 ohm microstrip signal paths be used. termination at transceiver inputs r1 = r4 = r6 = r8 = r10 = 130 ohms. r2 = r3 = r5 = r7 = r9 = 82 ohms. c1 = c2 = c3 = c5 = c6 = 0.1 ?. c4 = 10 ?. l1 = l2 = 1 ? coil or ferrite inductor. rx rx tx tx v cc v cc

146 11. these optical power values are measured with the following conditions: ? the beginning of life (bol) to the end of life (eol) optical power degradation is typically 1.5 db per the industry convention for long wavelength leds. the actual degradation observed in hewlett- packards 1300 nm led products is < 1 db, as specified in this data sheet. ? over the specified operating voltage and temperature ranges. ? with halt line state, (12.5 mhz square-wave), input signal. ? at the end of one meter of noted optical fiber with cladding modes removed. the average power value can be converted to a peak power value by adding 3 db. higher output optical power transmitters are available on special request. 12. the same comments of note 11 apply except that industry conven- tion for short wavelength led (800 nm) bol to eol aging is 3 db. this value for output optical power will provide a minimum of a 6 db optical power budget at the eol, which will provide at least 500 meter link lengths with margin left over for overcoming normal passive losses, such as in line connectors, in the cable plant. the actual degradation observed in normal commercial environments will be considerably less than this amount with hewlett- packards 800 nm led products. please consult with your local hp sales representative for further details. 13. the extinction ratio is a measure of the modulation depth of the optical signal. the data 0 output optical power is compared to the data 1 peak output optical power and expressed as a percentage. with the transmitter driven by a halt line state (12.5 mhz square-wave) signal, the average optical power is measured. the data 1 peak power is then calculated by adding 3 db to the measured average optical power. the data 0 output optical power is found by measuring the optical power when the transmitter is driven by a logic 0 input. the extinction ratio is the ratio of the optical power at the 0 level compared to the optical power at the 1 level expressed as a percentage or in decibels. 14. the transmitter provides compliance with the need for transmit_disable commands from the fddi smt layer by providing an output optical power level of < -45 dbm average in response to a logic 0 input. this specification applies to either 62.5/125 m m or 50/125 m m fiber cables. 15. this parameter complies with the fddi pmd requirements for the tradeoffs between center wave- length, spectral width, and rise/fall times shown in figure 9. 16. this parameter complies with the optical pulse envelope from the fddi pmd shown in figure 10. the optical rise and fall times are measured from 10% to 90% when the transmitter is driven by the fddi halt line state (12.5 mhz square-wave) input signal. 16a. the optical rise and fall times are measured from 10% to 90% when the transmitter is driven by the fddi halt line state (12.5 mhz square-wave) input signal. 17. duty cycle distortion contributed by the transmitter is measured at a 50% threshold using an idle line state, 125 mbd (62.5 mhz square- wave), input signal. see application information - transceiver jitter performance section of this data sheet for further details. 18. data dependent jitter contributed by the transmitter is specified with the fddi test pattern described in fddi pmd annex a.5. see applica- tion information - transceiver jitter performance section of this data sheet for further details. 19. random jitter contributed by the transmitter is specified with an idle line state, 125 mbd (62.5 mhz square-wave), input signal. see application information - transceiver jitter performance section of this data sheet for further details. 20. this specification is intended to indicate the performance of the receiver section of the transceiver when input optical power signal characteristics are present per the following definitions. the input optical power dynamic range from the minimum level (with a window time-width) to the maximum level is the range over which the receiver is guaranteed to provide output data with a bit error ratio (ber) better than or equal to 2.5 x 10 -10 . ? at the beginning of life (bol) ? over the specified operating temperature and voltage ranges ? input symbol pattern is the fddi test pattern defined in fddi pmd annex a.5 with 4b/5b nrzi encoded data that contains a duty cycle base-line wander effect of 50 khz. this sequence causes a near worst case condition for inter-symbol interference. ? receiver data window time-width is 2.13 ns or greater and centered at mid-symbol. this worst case window time-width is the minimum allowed eye-opening presented to the fddi phy pm._data indication input (phy input) per the example in fddi pmd annex e. this minimum window time-width of 2.13 ns is based upon the worst case fddi pmd active input interface optical conditions for peak-to-peak dcd (1.0 ns), ddj (1.2 ns) and rj (0.76 ns) presented to the receiver. to test a receiver with the worst case fddi pmd active input jitter condition requires exacting control over dcd, ddj and rj jitter compo- nents that is difficult to implement with production test equipment. the receiver can be equivalently tested to the worst case fddi pmd input jitter conditions and meet the minimum output data window time- width of 2.13 ns. this is accom- plished by using a nearly ideal input optical signal (no dcd, insignificant ddj and rj) and measuring for a wider window time-width of 4.6 ns. this is possible due to the cumula- tive effect of jitter components through their superposition (dcd and ddj are directly additive and rj components are rms additive). specifically, when a nearly ideal input optical test signal is used and the maximum receiver peak-to-peak jitter contributions of dcd (0.4 ns), ddj (1.0 ns), and rj (2.14 ns) exist, the minimum window time-width becomes 8.0 ns -0.4 ns - 1.0 ns - 2.14 ns = 4.46 ns, or conservatively 4.6 ns. this wider window time- width of 4.6 ns guarantees the fddi pmd annex e minimum window time-width of 2.13 ns under worst case input jitter conditions to the hewlett-packard receiver. ? transmitter operating with an
147 idle line state pattern, 125 mbd (62.5 mhz square-wave), input signal to simulate any cross-talk present between the transmitter and receiver sections of the transceiver. 20a. all the conditions of note 20 apply except that the ber requirement is tightened to 1 x 10 -12 and the minimum window time-width test condition is narrowed from 4.6 ns to 3.7 ns to reflect the lesser amount of worst case input optical jitter as a result of shorter optical cable lengths and lower ber which are both attributes of the fddi lcf- pmd. 20b. all the conditions of note 20 apply except that the ber requirement is tightened to 1 x 10 -12 and the minimum window time-width test condition is adjusted to 4.2 ns to reflect the hfbr-5104 transmitter contributed jitter values per the specification table. 21. all conditions of note 20 apply except that the measurement is made at the center of the symbol with no window time-width. 21a. all the conditions of note 21 apply accept that the ber requirement is tightened to 1 x 10 -12 . 22. this value is measured during the transition from low to high levels of input optical power. 23. the signal detect output shall be asserted within 100 m s after a step increase of the input optical power. the step will be from a low input optical power, -45 dbm, into the range between greater than p a , and -14 dbm. the ber of the receiver output will be 10 -2 or better during the time, ls_max (15 m s) after signal detect has been asserted. see figure 12 for more information. 23a. the signal detect output shall be asserted within 100 m s after a step increase of the input optical power. the step will be from a low input optical power, -45 dbm, into the range -27 dbm 2 db. the ber of the receiver output will be 10 -2 or better during the time, ls_max (15 m s) after signal detect has been asserted. 24. this value is measured during the transition from high to low levels of input optical power. the maximum value will occur when the input optical power is either -45 dbm average or when the input optical power yields a ber of 10 -2 or better, whichever power is higher. 25. signal detect output shall be de- asserted within 350 m s after a step decrease in the input optical power from a level which is the lower of; -31 dbm or p d + 4 db (p d is the power level at which signal detect was deasserted), to a power level of -45 dbm or less. this step decrease will have occurred in less than 8 ns. the receiver output will have a ber of 10 -2 or better for a period of 12 m s or until signal detect is deasserted. the input data stream is the quiet line state. also, signal detect will be deasserted within a maximum of 350 m s after the ber of the receiver output degrades above 10 -2 for an input optical data stream that decays with a negative ramp func- tion instead of a step function. see figure 12 for more information. 25a. signal detect output shall be de- asserted within 350 m s after a step decrease in the input optical power. the step decrease signal shall have an on level of -27 dbm 2 db and an off power level of -45 dbm or less. this step decrease will have occurred in less than 8 ns. the receiver outputs within 12 m s after the step decrease in the optical power will not reproduce with an accuracy greater than 90% any spurious signals (e.g. symbols from adjacent physical link components or power supply ripple). the input data stream is the quiet line state. signal detect will also be deasserted within a maximum of 350 m s after the ber of the receiver output degrades above 10 -2 for an input optical data stream that decays with a negative ramp function with a response time > 8 ns. 26. systematic jitter (sj) contributed by the 800 nm transmitter is a com- bination of duty cycle distortion (dcd) and data dependent jitter (ddj). 27. random jitter contributed by the 800 nm transmitter is specified with an idle line state, 125 mbd (62.5 mhz square-wave), input signal.
