The transceivers are all supplied in the new industry standard 1x9 SIP package style with a choice of duplex SC or ST® connector interface. 150 HFBR-5106/5106T 1300 nm HFBR-5107/5107T 820 nm 100VG-AnyLAN Backbone Links The HFBR-5106/-5106T are 1300 nm products with optical performance compliant with the 100VG-AnyLAN PMD developed by IEEE 802.12. These transceivers are suitable for link lengths up to 2 km. Alternative 800 nm, Lower Cost 500 m Desktop Links The HFBR-5107 is a lower cost 800 nm alternative to the HFBR5106 for 100VG-AnyLAN links from the wiring closet to the desktop. It complies with the performance requirements of 802.12 as implemented by Hewlett-Packard at 800 nm wavelength. This transceiver will transfer the full range of 100VG-AnyLan Signals at the required 1x10–8 Bit Error Rate over distances up to 500 meters using 62.5/125 µm multimode fiber cables. This product is intended for use in cost sensitive applications where the benefits of fiber optic links are important. Transmitter Sections The transmitter sections of the HFBR-5106 utilize 1300 nm Surface Emitting InGaAsP LEDs and the HFBR-5107 uses a low cost 820 nm AlGaAs LED. 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 +5 Volt supply, into an analog LED drive current. Receiver Sections The receiver section of the HFBR-5106 utilizes InGaAs PIN photodiodes coupled to a custom silicon transimpedance preamplifier IC. The HFBR-5107 series uses the same preamplifier IC in conjunction with an inexpensive silicon PIN photodiode. These are packaged in the optical subassembly portion of the receiver. 5965-7785E (4/97) These PlN/preamplifier combinations are coupled to a custom quantizer IC which provides the final pulse shaping for the logic output and Signal Detect function. The data output is differential. The signal detect output is single-ended. Both data and signal detect outputs are PECL compatible, ECL referenced (shifted) to a +5 Volt power supply. Package The overall package concept for the HP transceivers consists of the following basic elements; two optical subassemblies, an electrical subassembly, and the housing with integral duplex SC connector receptacles. This is illustrated in Figure 1. The package outline and pinout are shown in Figures 2 and 3. The details of this package outline and pinout are compliant with the multisource definition of the 1x9 SIP. The low profile of the Hewlett- Packard 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 process together with low cost lens elements which result in a cost effective transceiver. Application Information The electrical subassembly consists of a high volume multi-layer printed circuit board on which the IC chips and various surface mount passive circuit elements are attached. The package includes internal shields for the electrical and optical subassemblies to ensure low EMI and high immunity to electromagnetic fields. The outer housing, including the duplex SC connector receptacle, is molded of filled non-conductive plastic to provide mechanical strength and electrical isolation. The solder posts of the HewlettPackard 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 duplex ELECTRICAL SUBASSEMBLY DIFFERENTIAL DATA OUT DUPLEX SC RECEPTACLE PIN PHOTODIODE SINGLE-ENDED SIGNAL DETECT OUT QUANTIZER IC PREAMP IC DIFFERENTIAL DATA IN OPTICAL SUBASSEMBLIES LED DRIVER IC TOP VIEW Figure 1.

The Application Engineering group in the Hewlett-Packard Optical Communications 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 inline 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 two transceivers 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 µm and 50/125 µm fiber cables only. The area under the curve represents the remaining OPB at any link length, which is available for overcoming non-fiber cable related losses.

Optical Power Budget at BOL vs. 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). Table 1 lists the hub control signals defined in IEEE 802.12, section 18.5.4.1. These signal rates are below 10 MBd but they are transported with adequate accuracy for hub access control. When used in 100VG AnyLAN 100 Mbps applications, the performance of the 1300 nm transceiver is guaranteed over the signaling rate of 10 MBd to 120 MBd to the full conditions listed in the individual product specification tables. Transceiver Jitter Performance The Hewlett-Packard 1300 nm transceivers are designed to operate per the system interface jitter specifications listed in Table 27 of section 18.9. of the IEEE 802.12 (100VG-AnyLAN standards). The transceivers may be used for other applications at signaling rates outside of the 10 MBd to 120 MBd range with some penalty in the link optical power 3.0 1 x 10-2 2.5 1 x 10-3 2.0 1.5 1.0 0 HFBR-510X 1 x 10-4 1 x 10-5 CENTER OF SYMBOL 1 x 10-6 1 x 10-7 1 x 10-8 2.5 x 10-10 1 x 10-11 1 x 10-12 0.5 0 25 50 75 100 125 150 175 200 SIGNAL RATE (MBd) CONDITIONS: 1.

Figure 6 illustrates the typical trade-off between link BER and the receivers input optical power level. BIT ERROR RATE Figure 4 was generated with a Hewlett-Packard fiber optic link module containing the current industry conventions for fiber cable specifications and the 100VG-AnyLAN 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 X3T and IEEE committees, including the ANSI X3T12 committee, to establish the optical performance requirements for various fiber optic interface standards. The cable parameters used come from the ISO/IEC JTCI/SC 25/WG3 Generic Cabling for Customer 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.

TRANSCEIVER RELATIVE OPTICAL POWER BUDGET AT CONSTANT BER (dB) normally associated with these technologies in the industry. The Industry convention is 3 dB aging for 800 nm and 1.5 dB for 1300 nm LEDs. The HP LEDs will normally experience less than 1 dB of aging over normal commercial equipment mission life periods.

The Active Output Specifications of the 100VG-AnyLAN standard are met by the HFBR-5106. The HP 1300 nm receivers tolerate the worst case input optical response time and systematic jitter shown in Table 27 of Section 18.9. The Active Input Specification of the IEEE 802.12 100VG-AnyLAN standard are met by the HBFR-5106. The jitter specifications stated in the 1300 nm transceiver specification tables are derived from the values in Table 27 of section 18.9 of the IEEE 802.12 specification. They represent the worst case jitter contributions from the transceiver meeting the overall system jitter in Annex E. In practice the typical jitter contribution of the HP transceivers is well below these maximum allowed values. Recommended Handling Precautions It is advised 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-510X series of transceivers are certified as Mil-Std-883C Method 3015.4 Class 1 products.

Solder and Wash Process Compatibility The transceivers are delivered with a protective process plug inserted into the duplex SC 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 compatible with either industry standard wave or hand soldering 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 155 Regulatory Compliance Table Feature Electrostatic Discharge (ESD) to the Electrical Pins Electrostatic Discharge (ESD) to the Duplex SC Receptacle Electromagnetic Interference (EMC) Immunity Test Method MIL-STD-883C Method 3015.4 Variation of IEC 801-2 Performance Certified to Class 1 (0 to 1999 Volts) Withstand up to 1800 V applied between electrical pins.

FCC Class B Typically provide a 10 dB margin to the noted CENELEC CEN55022 standard limits when tested at a certified test range Class B (CISPR 22B) with the transceiver mounted to a circuit card VCCI Class 2 without a chassis enclosure. Variation of IEC 801-3 Typically show no measurable effect from a 10 V/m field swept from 10 to 450 MHz applied to the transceiver when mounted to a circuit card without a chassis enclosure. well. 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 This Hewlett-Packard transceiver complies with the circuit board “Common Transceiver Footprint” hole pattern defined in the original multisource announcement which defined the 1x9 package style. This drawing is reproduced in Figure 8 with the addition of ANSI Y14.5N compliant dimensioning to be used as a guide in the mechanical layout of your circuit board. Board Layout – Art Work The Applications Engineering group has developed Gerber file artwork for a multilayered printed circuit board layout incorporating the above recommendations. Contact your local Hewlett- 156 Packard sales representative for details. 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. Regulatory Compliance These transceiver products are intended to enable commercial system designers to develop equipment that complies with the various international regulations governing certification of Information Technology Equipment. See the Regulatory Compliance Table for details. Additional information is available from your Hewlett-Packard sales representative. Electrostatic Discharge (ESD) There are two design cases in which immunity to ESD damage is important. The first case is during handling of the transceiver prior to mounting it on the circuit board. It is important to use normal ESD handling precautions for ESD sensitive devices. These precautions include using grounded wrist straps, work benches, and floor mats in ESD controlled areas. The second case is static discharges to the exterior of the equipment chassis containing the transceiver parts. To the extent that the duplex SC connector is exposed to the outside of the equipment chassis it may be subject to whatever ESD system level test criteria that the equipment is intended to meet.

The outputs are terminated with 50 Ω connected to VCC –2 V. 3. The power supply current needed to operate the transmitter is supplied to differential ECL circuitry. This circuitry maintains a nearly constant current from the power supply. Constant current operation helps to prevent unwanted electrical noise from being generated and conducted or emitted to neighboring circuitry. 4. This value is measured with the outputs terminated into 50 Ω connected to VCC –2 V and an Input Optical Power Level of –14 dBm average. 5. The power dissipation value is the power dissipated in the receiver itself. Power dissipation is calculated as the sum of the products of supply voltage and currents, minus the sum of the products of the output voltages and currents. 6. This value is measured with respect to VCC with the output terminated into 50 Ω connected to VCC –2 V. 7. The output electrical rise and fall times are measured between 20% and 80% levels with the output connected to VCC –2 V through 50 Ω. 8. Random Jitter contributed by the receiver is specified with a 120 MBd (60 MHz square-wave) input signal. The input optical power level is at maximum "PIN MIN. (W)". 9. These optical power values are measured with the following conditions: • At the Beginning of Life (BOL). The actual FDDI specification is 1.5 dB lower power at the End of Life for the equipment. The definition of Beginning of Life (BOL) to the End of Live (EOL) optical power degradation is assumed to be 1.0 dB per the industry convention for 1300 nm LEDs. The actual degradation observed in normal commercial environments is considerably less than this amount with Hewlett-Packard’s 1300 nm LED products. • At the end of one meter of noted fiber with cladding modes removed. • Over the specified operating voltage and temperature ranges. • (12.5 MHz square-wave) input signal. The average power value can be converted to a peak power value by adding 3 dB. Higher output optical power transmitters are available upon special request. 10. The same comments of Note 9 apply except that industry convention for 800 nm LED BOL to EOL aging is 3 dB. This value for Output Optical Power provides a minimum of 7.5 dB optical power budget at the EOL, which provides 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 is considerably less than this amount with Hewlett-Packard 800 nm LED products. 11. The transmitter provides compliance with 802.12. An Output Optical Power level of <–45 dBm average in response to a logic "0" input. This specification applies to either 62.5/125 µm or 50/125 µm fiber cables. 12. This parameter complies with 802.12. 13. The optical rise and fall times are measured from 10% to 90% when the transmitter is driven by a 12.5 MHz square-wave input signal. 14. The optical rise and fall times are measured from 10% to 90% when the transmitter is driven by a 12.5 MHz square-wave input signal. 15. Random Jitter contributed by the transmitter is specified with a 60 MBd square-wave input signal. 16. 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 10-8. • At the Beginning of Life (BOL). • Over the specified operating temperature and voltage ranges. • Receiver data window opening timewidth is 2.2 ns or greater and centered at mid-symbol. This worst case window opening time-width is the minimum allowed eye-opening presented to the PHY input per 802.12. This minimum window time-width of 2.2 ns is based upon the worst case 802.12 Active Input Interface optical conditions peak-topeak SJ (1.6 ns) and RJ (0.77 ns) presented to the receiver. To test a receiver with the worst case 802.12 Active Input Jitter condition requires exacting control over SJ and RJ jitter components. This is difficult to implement with production test equipment. The receiver can be equivalently tested to the worst case 802.12 input jitter conditions and meet the minimum output data window time-width of 2.2 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 4.0 ns. This is possible due to the cumulative addition of jitter components through their superposition. (SJ is 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 SJ (X.Xns), and RJ (X.Xns) exist, the minimum window time-width becomes 4.4 ns. This wider window time-width of 4.4 ns guarantees the 802.12 time-width of 2.2 ns under worst case input jitter conditions to the Hewlett-Packard receiver. • Transmitter operating with a 120 MBd (60 MHz square-wave), input signal to simulate any cross-talk present between the transmitter and receiver sections of the transceiver. 16a. All conditions of Note 16 apply except that the BER requirement is tightened to 1x10-8 and the minimum window time-width test condition is adjusted to 5.2 ns to reflect the HFBR-5107 transmitter contributed jitter values per the specification table. 17. All conditions of Note 16 apply except that the measurement is made at the center of the symbol with no window time-width. 17a. All conditions of Note 17 apply except that the BER requirement is tightened to 1x10-8. 18. This value is measured during the transition from low to high levels of input optical power. 19. The high_light (Signal Detect) output shall be asserted within 100 µs 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 Pm and (Pm + 4 dB). Pm is the relevant 163 minimum allowed input average optical power for the PMD at the AI as defined in Figure 10. (The input optical power is averaged over a period of 1 µs or more). 20. The high_light (Signal Detect) output shall be asserted within 100 µs 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 Pm and (Pm + 4 dB). Pm is the relevant minimum allowed input average optical power for the PMD at the AI as defined in Figure 10. (The input optical power is averaged over a period of 1 µs or more). 21. This value is measured during the transition from high to low levels of input optical power. The maximum 164 value will occur when the input optical power is –45 dBm average or when the input optical power yields a BER of 102 or better, whichever power is higher. 22. The low_light (Signal Detect) output shall be deasserted within 350 µs after valid IEEE 802.12 optical signals cease to be present at the AI and the input average optical power at AI has fallen monitonically from a level between (Pm +4 dB) and Pm to a level below –45 dBm and remain below –45 dBm (see Figure 10). (The input optical power is averaged over a period of 1 µs or more.) 22. The low_light (Signal Detect) output shall be deasserted within 350 µs after valid IEEE 802.12 optical signals cease to be present at the AI and the input average optical power at AI, has fallen monitonically from a level between (Pm +4 dB) and Pm to a level below – 45 dBm and remain below –45 dBm (see Figure 10). (The input optical power is averaged over a period of 1 µs or more.) 23. Systematic Jitter (SJ) contributed by the 800 and 1300 nm transmitter is a combination of Duty Cycle Distortion (DCD) and Data Dependent Jitter (DDJ). 24. Random Jitter contributed by the 800 and 1300 nm transmitter is specified with an IDLE Line State, 125 MBd (62.5 MHz square-wave), input signal.
