2.2.9 INTER-RELAY COMMUNICATIONS
SHIELDED TWISTED-PAIR INTERFACE OPTIONS
RS422 distance is based on transmitter power and
does not take into consideration the clock source
provided by the user.
LINK POWER BUDGET
These power budgets are calculated from the manu-
facturer’s worst-case transmitter power and worst
case receiver sensitivity.
The power budgets for the 1300 nm ELED are calcu-
lated from the manufacturer's transmitter power and
receiver sensitivity at ambient temperature. At
extreme temperatures these values deviate based
on component tolerance. On average, the output
power decreases as the temperature 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

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