2 PRODUCT DESCRIPTION
The power budgets for the 1300nm ELED are cal-
culated from the manufacturer's transmitter
NOTE
power and receiver sensitivity at ambient temper-
ature. At extreme temperatures these values will
deviate based on component tolerance. On aver-
age, the output power will decrease as the tem-
perature is increased by a factor 1dB / 5°C.

Typical distances listed are based on the fol-
lowing assumptions for system loss. As
NOTE
actual losses will vary from one installation to
another, the distance covered by your system
may vary.
