All HFBR-15XX LED transmitters are classified as IEC 825-1 Accessible Emission Limit (AEL) Class 1
based upon the current proposed draft scheduled to go into effect on January 1, 1997. AEL Class 1 LED
devices are considered eye safe. Contact your Avago sales representative for more information.

Note 1
Note:
1. Rise and fall times are measured with a voltage pulse driving the transmitter and a series connected 50
Ω
load. A wide bandwidth optical to
electrical waveform analyzer, terminated to a 50
Ω
input of a wide bandwidth oscilloscope, is used for this response time measurement.
