2 figure 1. sc connector block diagram. transmitter sections the transmitter section of the afbr-5803z and afbr-5805z series utilize 1300 nm surface emitting ingaasp leds. these leds are packaged in the optical subassembly portion of the transmitter section. they are driven by a custom silicon ic which converts differential pecl logic signals, ecl referenced (shifted) to a +3.3 v or +5 v supply, into an analog led drive current. receiver sections the receiver sections of the afbr-5803z and afbr-5805z series u tilize ingaas pin photodiodes coupled to a custom silicon transimpedance preamplifier ic. these are packaged in the optical sub- assembly portion of the receiver. these pin/preamplifier combi- nations are coupled to a custom quantizer ic which provides the final pulse shaping for the logic output and the signal detect function. the data output is dif ferential. the signal detect output is single-ended. both data and signal detect outputs are pecl compatible, ecl referenced (shifted) to a +3.3 v or +5 v power supply. package the overall package concept for the agilent transceivers consists of the following basic elements; two optical subassemblies, an electrical subassembly and the housing as illustrated in figure 1 and figure 1a. the package outline drawings and pin out are shown in figures 2, 2a and 3. the details of this package outline and pin out are compliant with the multisource definition of the 1 x 9 sip. the low profile of the agilent transceiver design complies with the maximum height allowed for the duplex sc connector over the entire length of the package. the optical subassemblies utilize a high volume assembly process together with low cost lens elements which result in a cost effective building block. the electrical subassembly consists of a high volume multilayer printed circuit board on which the ic chips and various surface-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 nonconductive plastic to provide mechanical strength and electrical isolation. the solder posts of the agilent 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 transceiver by mating with duplex or simplex sc or st connectored fiber cables. top view pin photodiode duplex sc receptacle optical subassemblies led preamp ic data out signal detect out data in electrical subassembly quantizer ic driver ic differential single-ended differential

5 application information the applications engineering group in the agilent fiber optics communication division is available to assist you with the technical understanding and design trade-offs associated with these trans- ceivers. you can contact them through your agilent 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 pre- dicted opb associated with the 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 and 50/ 125 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. agilent led technology has produced 1300 nm led devices with lower aging characteristics than normally associated with these technologies in the industry. the industry convention is 1.5 db aging for 1300 nm leds. the agilent 1300 nm leds will experience less than 1 db of aging over normal commercial equipment mission life periods. contact your agilent sales representative for additional details. figure 4 was generated with a agilent 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 document and the eia/tia-568-a commercial building telecommunications cabling standard per sp-2840. figure 4. optical power budget at bol versus fiber optic cable length. transceiver signaling operating rate range and ber performance for purposes of definition, the symbol (baud) rate, also called signaling rate, is the reciprocal of the shortest symbol time. data rate (bits/sec) is the symbol rate divided by the encoding factor used to encode the data (symbols/bit). when used in fast ethernet, fddi and atm 100 mb/s applications the performance of the 1300 nm transceivers is guaranteed over the signaling rate of 10 mbd to 125 mbd to the full conditions listed in individual product specification tables. figure 5. transceiver relative optical power budget at constant ber vs. signaling rate. the transceivers may be used for other applications at signaling rates outside of the 10 mbd to 125 mbd range with some penalty in the link optical power budget primarily caused by a reduction of receiver sensitivity. figure 5 gives an indication of the typical performance of these 1300 nm products at different rates. these transceivers can also be used for applications which require different bit error rate (ber) performance. figure 6 illustrates the typical trade-off between link ber and the receivers input optical power level. transceiver relative optical power budget at constant ber (db) 0 200 0 signal rate (mbd) 25 75 100 125 2.5 2.0 1.5 1.0 175 0.5 50 150 conditions: 1. prbs 2 7 -1 2. data sampled at center of data symbol. 3. ber = 10 -6 4. t a = +25? c 5. v cc = 3.3 v to 5 v dc 6. input optical rise/fall times = 1.0/2.1 ns. 0.5 optical power budget (db) 0 fiber optic cable length (km) 0.5 1.5 2.0 2.5 12 10 8 6 4 2 1. 0 0.3 afbr-5803, 62.5/125 m afbr-5803 50/125 m

7 figure 8. recommended board layout hole pattern 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 ground plane be provided in the circuit board directly under the transceiver to provide a low inductance ground for signal return current. this recommendation is in keeping with good high frequency board layout practices. board layout - hole pattern the agilent transceiver complies with the circuit board common transceiver footprint hole pattern defined in the original multisource announcement which defined the 1 x 9 package style. this drawing is reproduced in figure 8 with the addition of ansi y14.5m compliant dimensioning to be used as a guide in the mechanical layout of your circuit board. board layout - mechanical for applications providing a choice of either a duplex sc or a duplex st connector interface, while utilizing the same pinout on the printed circuit board, the st port needs to protrude from the chassis panel a minimum of 9.53 mm for sufficient clearance to install the st connector. please refer to figure 8a for a mechanical layout detailing the recommended location of the duplex sc and duplex st transceiver packages in relation to the chassis panel. 20.32 (0.800) top view 2 x ? 1.9 0.1 (0.075 0.004) 20.32 (0.800) 2.54 (0.100) 9 x ? 0.8 0.1 (0.032 0.004) dimensions are in millimeters (inches)

15 14. this parameter complies with the fddi pmd requirements for the trade-offs between center wavelength, spectral width, and rise/ fall times shown in figure 9. 15. 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. 16. 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. 17. data dependent jitter contributed by the transmitter is specified with the fddi test pattern described in fddi pmd annex a.5. see application information - transceiver jitter performance section of this data sheet for further details. 18. 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. 19. 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 components 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 accomplished 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 cumulative 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 agilent receiver. transmitter operating with an 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. 20. all conditions of note 19 apply except that the measurement is made at the center of the symbol with no window time-width. 21. this value is measured during the transition from low to high levels of input optical power. 22. the signal detect output shall be asserted within 100 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 s) after signal detect has been asserted. see figure 12 for more information. 23. 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 larger, whichever power is higher. 24. signal detect output shall be de-asserted within 350 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 de- asserted), 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 s or until signal detect is de-asserted. the input data stream is the quiet line state. also, signal detect will be de- asserted within a maximum of 350 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 instead of a step function. see figure 12 for more information.
