except that industry convention for
short wavelength LED (800 nm)
aging is 3 dB. This value for Output
Optical Power will provide a
minimum 6 dB optical power budget
at the EOL, which will provide at
least 150 meter link lengths with
margin left over for overcoming
normal passive losses, such as in-
line connectors, in the cable plant.
The actual degradation observed in
normal commercial environments
will be considerably less than this
amount with Hewlett-Packard’s 800
nm LED products. Please consult

tive for further details.

The average power value can be
converted to a peak power value
by adding 3 dB. Higher output
