The power budgets for the 1300nm ELED are cal-
culated from the manufacturer's transmitter
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.
MAXIMUM OPTICAL INPUT POWER
TYPICAL LINK DISTANCE
Compensated difference in transmitting and receiving (channel
asymmetry) channel delays using GPS satellite clock: 10 ms
2.2.10 ENVIRONMENTAL

Typical distances listed are based on the fol-
lowing assumptions for system loss. As
actual losses will vary from one installation to
another, the distance covered by your system
may vary.
CONNECTOR LOSSES (TOTAL OF BOTH ENDS)
ST connector 2 dB
FIBER LOSSES
820 nm multimode 3 dB/km
1300 nm multimode 1 dB/km
1300 nm singlemode 0.35 dB/km
1550 nm singlemode 0.25 dB/km
Splice losses: One splice every 2 km,
at 0.05 dB loss per splice.
SYSTEM MARGIN
3 dB additional loss added to calculations to compensate for
all other losses.
