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. Recommended Chemicals for Cleaning/Degreasing HFBR-0400 Products Alcohols: methyl, isopropyl, isobutyl. Aliphatics: hexane, heptane, Other: soap solution, naphtha. Do not use partially halogenated hydrocarbons such as 1,1.1 trichloroethane, ketones such as MEK, acetone, chloroform, ethyl acetate, methylene dichloride, phenol, methylene chloride, or N-methylpyrolldone. Also, HP does not recommend the use of cleaners that use halogenated hydrocarbons because of their potential environmental harm.

5 MBd Logic Link Design
If resistor R1 in Figure 2 is 70.4 , a forward current IF of 48 mA is applied to the HFBR14X4 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 , 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. VCC - VF 5 V - 1.5 V R1 = ------- = --------- 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 LowCost High-Speed 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 HewlettPackard 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.

When changing W to dBm, the optical power is referenced to 1 mW (1000 W). Optical Power P (dBm) = 10 log P (W)/1000 W. 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 Hewlett-Packard sales representative for more information.

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 pulse-width 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 HewlettPackard 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 Hewlett-Packard HFBR14XX 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 open-collector 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 F ceramic) be connected from Pin 2 (VCC) to Pin 3 (circuit common) of the receiver.

Consequently it is a combination of data-rate-limiting 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.

HFBR-24X6 Low-Cost 125 MHz Receiver Description
The HFBR-24X6 fiber optic receiver is designed to operate with the Hewlett-Packard HFBR14XX 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 m 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 tradeoff 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 pre-amplifier
BIAS & FILTER CIRCUITS
integrated circuit. The HFBR-24X6 receives an optical signal and converts it to an analog voltage. The output is a buffered emitterfollower. 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 12. It is essential that a 10 ohm resistor be connected between pin 6 and the power supply, and a 0.1 F ceramic bypass capacitor be connected between the power supply and ground. In addition, pin 6 should be filtered to protect the

receiver from noisy host systems. Refer to AN 1038, 1065, or AB 78 for details.

The conductive port option for the Low Cost Miniature Link component family consists of a grounding path from the conductive port to four grounding pins as shown in the package outline drawing. Signal ground is separate from the four grounding pins to give the designer more flexibility. This option is available with all SMA and ST panel mount styled port receivers. Electrical/optical performance of the receivers is not affected by the conductive port. Refer to the HFBR-0400 data sheets for more information.

Notes: 1. Tests were performed on both SMA an ST products with the conductive port option. 2. The Port Strength test was designed to address the concerns with hand tightening the SMA connector to the fiber optic port. The limit is set to a level beyond most reasonable hand fastening loading. 3. HP has previously used an air discharge method to measure ESD; results using this method vary with air temperature and humidity. The direct contact discharge method is perferred due to better repeatability and conformance with IEC procedures. ESD immunity measured with the air discharge method is generally higher than with the direct contact discharge method.

Metal Port Option for HFBR-0400 Series Components Technical Data
Option M
Features
* Nickel Plated Aluminum Connector Receptacle * Withstands Electro-static Discharge (ESD) of 15 kV to the Port * Significantly Decreases Effect of Electro-magnetic Interference (EMI) on Receiver Sensitivity * Allows Separate Signal and Metal Port Grounds * Available with SMA, ST, Threaded ST, and FC Styled Ports
This feature aids in maintaining the integrity of the signal ground if the chassis is exposed to electrical noise. In addition, when the metal port is in good electrical contact with a well-grounded chassis, the metal port provides additional EMI shielding from electrically noisy circuits.
Applications
HP recommends that the designer use separate ground paths for the signal ground and the conductive metal port ground in order to minimize the effects of external coupled noise on receiver circuitry. If noise is present on the system chassis, care should be taken to electrically isolate the metal port from the chassis. In the case of ESD, the metal port option does not alleviate the need for system recovery procedures. A 15 kV ESD event entering through the connector port will not cause catastrophic failure, but the metal port does not guarantee error-free performance during an ESD event. The Metal Port Option is available with SMA, ST, Threaded ST (panel mount) and FC styled port transmitters and receivers. The electrical/optical specifications, the mechanical dimensions, and the pinouts of the components with metal ports are identical to the standard plastic port products.
Description
The metal port option for the HFBR-0400 Series gives designers the ability to have a metal connector receptacle with the familiar HFBR-0400 dual inline package (DIP). The metal port option components have an internal electrical connection between the metal port and the four grounding pins, as shown in the package outline drawing. Signal ground is separate from the four grounding pins to give the flexibility in connecting the port to signal or chassis ground.
