Notes:

1. For IFPK > 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® precision ceramic ferrule (MIL-

STD-83522/13) for HFBR-1412/1414, and with an SMA 905 precision ceramic ferrule for HFBR-1402/1404.

6. When changing µW to dBm, the optical power is referenced to 1 mW (1000 µW). Optical Power P (dBm) = 10 log P (µW)/1000 µW.

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.

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.
