SHIELDED TWISTED-PAIR INTERFACE OPTIONS
Interface type
RS422
G.703
RS422 distance is based on transmitter power and does not take into consideration the clock source provided
by the user.

LINK POWER BUDGET
Emitter, fiber type
820 nm LED, Multimode
1300 nm LED, Multimode
1300 nm ELED, Single mode
1300 nm Laser, Single mode
1550 nm Laser, Single mode
These power budgets are calculated from the manufacturer's worst-case transmitter power and worst case
receiver sensitivity.
NOTE
The power budgets for the 1300 nm ELED are calculated 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
1 dB / 5 °C.
