HFBR-0400 Series Evaluation Kits HFBR-0410 ST Evaluation Kit Contains the following:
Package and Handling Information Package Information All HFBR-0400 Series transmitters and receivers are housed in a low-cost, dual-inline package that is made of high strength, heat resistant, chemically resistant, and UL 94V-O flame retardant ULTEM(R) plastic (UL File #E121562). The transmitters are easily identified by the light grey color connector port. The receivers are easily identified by the dark grey color connector port. (Black color for conductive port). The package is designed for auto-insertion and wave soldering so it is ideal for high volume production applications. Handling and Design Information Each part comes with a protective port cap or plug covering the optics. These caps/ plugs will vary by port style. When soldering, it is advisable to leave the protective cap on the unit to keep the optics clean. Good system performance requires clean port optics and cable ferrules to avoid obstructing the optical path. Clean compressed air often is sufficient to remove particles of dirt; methanol on a cotton swab also works well.

Notes: 1. OPB at TA = -40 to +85 C, V CC = 5.0 V dc, IF ON = 60 mA. PR = -24 dBm peak. 2. Synchronous data rate limit is based on these assumptions: a) 50% duty factor modulation, e.g., Manchester I or BiPhase Manchester II; b) continuous data; c) PLL Phase Lock Loop demodulation; d) TTL threshold. 3. Asynchronous data rate limit is based on these assumptions: a) NRZ data; b) arbitrary timing-no duty factor restriction; c) TTL threshold.

5 MBd Logic Link Design If resistor R1 in Figure 2 is 70.4 W, a forward current IF of 48 mA is applied to the HFBR-14x4 LED transmitter. With IF = 48 mA the HFBR-14x4/24x2 logic link is guaranteed to work with 62.5/125 m fiber optic cable over the entire range of 0 to 1750 meters at a data rate of dc to 5 MBd, with arbitrary data format and pulse width distortion typically less than 25%. By setting R1 = 115 W, the transmitter can be driven with IF = 30 mA, if it is desired to economize on power or achieve lower pulse distortion.
The following example will illustrate the technique for selecting the appropriate value of IF and R1. Maximum distance required = 400 meters. From Figure 3 the drive current should be 15 mA. From the transmitter data VF = 1.5 V (max.) at IF = 15 mA as shown in Figure 9.
R1 = VCC - VF = 5V - 1.5V IF 15 mA R1 = 233
The curves in Figures 3, 4, and 5 are constructed assuming no inline splice or any additional system loss. Should the link consists of any in-line splices, these curves can still be used to calculate link limits provided they are shifted by the additional system loss expressed in dB. For example, Figure 3 indicates that with 48 mA of transmitter drive current, a 1.75 km link distance is achievable with 62.5/125 m fiber which has a maximum attenuation of 4 dB/km. With 2 dB of additional system loss, a 1.25 km link distance is still achievable.

HFBR-14x2/14x4 Low-Cost HighSpeed Transmitters Description The HFBR-14xx fiber optic transmitter contains an 820 nm AlGaAs emitter capable of efficiently launching optical power into four different optical fiber sizes: 50/125 m, 62.5/125 m, 100/140 m, and 200 m HCS(R). This allows the designer flexibility in choosing the fiber size. The HFBR-14xx is designed to operate with the Agilent HFBR-24xx fiber optic receivers. The HFBR-14xx transmitter's high coupling efficiency allows the emitter to be driven at low current levels resulting in low power consumption and increased reliability of the transmitter. The HFBR-14x4 high power transmitter is optimized for small size fiber and typically can launch -15.8 dBm optical power at 60 mA
into 50/125 m fiber and -12 dBm into 62.5/125 m fiber. The HFBR-14x2 standard transmitter typically can launch -12 dBm of optical power at 60 mA into 100/140 m fiber cable. It is ideal for large size fiber such as 100/140 m. The high launched optical power level is useful for systems where star couplers, taps, or inline connectors create large fixed losses. Consistent coupling efficiency is assured by the double-lens optical system (Figure 1). Power coupled into any of the three fiber types varies less than 5 dB from part to part at a given drive current and temperature. Consistent coupling efficiency reduces receiver dynamic range requirements which allows for longer link lengths.

Notes: 1. For I FPK > 100 mA, the time duration should not exceed 2 ns. 2. Typical data at TA = +25 C. 3. Thermal resistance is measured with the transmitter coupled to a connector assembly and mounted on a printed circuit board. 4. D is measured at the plane of the fiber face and defines a diameter where the optical power density is within 10 dB of the maximum. 5. PT is measured with a large area detector at the end of 1 meter of mode stripped cable, with an ST(R) precision ceramic ferrule (MILSTD- 83522/13) for HFBR-1412/1414, and with an SMA 905 precision ceramic ferrule for HFBR-1402/1404. 6. When changing mW to dBm, the optical power is referenced to 1 mW (1000 mW). Optical Power P (dBm) = 10 log P (mW)/1000 mW. 7. Pre-bias is recommended if signal rate >10 MBd, see recommended drive circuit in Figure 11. 8. Pins 2, 6 and 7 are welded to the anode header connection to minimize the thermal resistance from junction to ambient. To further reduce the thermal resistance, the anode trace should be made as large as is consistent with good RF circuit design. 9. Fiber NA is measured at the end of 2 meters of mode stripped fiber, using the far-field pattern. NA is defined as the sine of the half angle, determined at 5% of the peak intensity point. When using other manufacturer's fiber cable, results will vary due to differing NA values and specification methods.
All HFBR-14XX LED transmitters are classified as IEC 825-1 Accessible Emission Limit (AEL) Class 1 based upon the current proposed draft scheduled to go in to effect on January 1, 1997. AEL Class 1 LED devices are considered eye safe. Contact your Agilent sales representative for more information. CAUTION: The small junction sizes inherent to the design of these components increase the components' susceptibility to damage from electrostatic discharge (ESD). It is advised that normal static precautions be taken in handling and assembly of these components to prevent damage and/or degradation which may be induced by ESD.

Recommended Drive Circuits The circuit used to supply current to the LED transmitter can significantly influence the optical switching characteristics of the LED. The optical rise/fall times and propagation delays can be improved by using the appropriate circuit techniques. The LED drive circuit shown in
Figure 11 uses frequency compensation to reduce the typical rise/fall times of the LED and a small pre-bias voltage to minimize propagation delay differences that cause pulsewidth distortion. The circuit will typically produce rise/fall times of 3 ns, and a total jitter including pulse-width distortion of less than 1 ns. This circuit is recommended for applications requiring low edge jitter or high-
speed data transmission at signal rates of up to 155 MBd. Component values for this circuit can be calculated for different LED drive currents using the equations shown below. For additional details about LED drive circuits, the reader is encouraged to read Agilent Application Bulletin 78 and Application Note 1038.

HFBR-24x2 Low-Cost 5 MBd Receiver Description The HFBR-24x2 fiber optic receiver is designed to operate with the Agilent HFBR-14xx fiber optic transmitter and 50/ 125 m, 62.5/125 m, 100/ 140 m, and 200 m HCS(R) fiber optic cable. Consistent coupling into the receiver is assured by the lensed optical system (Figure 1). Response does not vary with fiber size 0.100 m. The HFBR-24x2 receiver incorporates an integrated photo IC containing a photodetector and dc amplifier driving an opencollector Schottky output transistor. The HFBR-24x2 is
designed for direct interfacing to popular logic families. The absence of an internal pull-up resistor allows the opencollector output to be used with logic families such as CMOS requiring voltage excursions much higher than VCC. Both the open-collector "Data" output Pin 6 and VCC Pin 2 are referenced to "Com" Pin 3, 7. The "Data" output allows busing, strobing and wired "OR" circuit configurations. The transmitter is designed to operate from a single +5 V supply. It is essential that a bypass capacitor (0.1 mF ceramic) be connected from Pin 2 (VCC) to Pin 3 (circuit common) of the receiver.

D is the effective diameter of the detector image on the plane of the fiber face. The numerical value is the product of the actual detector diameter and the lens magnification. 5. Measured at the end of 100/140 mm fiber optic cable with large area detector. 6. Propagation delay through the system is the result of several sequentially-occurring phenomena. Consequently it is a combination of data-ratelimiting effects and of transmission-time effects. Because of this, the data-rate limit of the system must be described in terms of time differentials between delays imposed on falling and rising edges. 7. As the cable length is increased, the propagation delays increase at 5 ns per meter of length. Data rate, as limited by pulse width distortion, is not affected by increasing cable length if the optical power level at the receiver is maintained.
CAUTION: The small junction sizes inherent to the design of these components increase the components' susceptibility to damage from electrostatic discharge (ESD). It is advised that normal static precautions be taken in handling and assembly of these components to prevent damage and/or degradation which may be induced by ESD.

HFBR-24x6 Low-Cost 125 MHz Receiver Description The HFBR-24x6 fiber optic receiver is designed to operate with the Agilent HFBR-14xx fiber optic transmitters and 50/ 125 m, 62.5/125 m, 100/140 m and 200 m HCS(R) fiber optic cable. Consistent coupling into the receiver is assured by the lensed optical system (Figure 1). Response does not vary with fiber size for core diameters of 100 mm or less. The receiver output is an analog signal which allows follow-on circuitry to be optimized for a variety of distance/data rate requirements. Low-cost external components can be used to convert the analog output to logic compatible signal levels for various data formats and data rates up to 175 MBd. This distance/data rate trade-off results in increased optical power budget at lower data rates which can be used for additional distance or splices. The HFBR-24x6 receiver contains a PIN photodiode and low noise transimpedance
preamplifier integrated circuit. The HFBR-24x6 receives an optical signal and converts it to an analog voltage. The output is a buffered emitter follower. Because the signal amplitude from the HFBR-24x6 receiver is much larger than from a simple PIN photodiode, it is less susceptible to EMI, especially at high signaling rates. For very noisy environments, the conductive or metal port option is recommended. A receiver dynamic range of 23 dB over temperature is achievable (assuming 10-9 BER). The frequency response is typically dc to 125 MHz. Although the HFBR-24x6 is an analog receiver, it is compatible with digital systems. Please refer to Application Bulletin 78 for simple and inexpensive circuits that operate at 155 MBd or higher. The recommended ac coupled receiver circuit is shown in Figure 14. It is essential that a 10 ohm resistor be connected between pin 6 and the power supply, and a 0.1 mF ceramic bypass capacitor be connected between the power supply and ground. In addition, pin 6 should be filtered to protect the
6 VCC POSITIVE SUPPLY
receiver from noisy host systems. Refer to AN 1038, 1065, or AB 78 for details. Housed Product
