Notes:
1. For I
2. Typical data at T
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. P
6. 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
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,

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.
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 Avago sales representative for
more information.
