2-32 L30 Line Current Differential System GE Multilin
2.5 SPECIFICATIONS 2 PRODUCT DESCRIPTION

The following specifications apply to filter interface modules implemented from January 2012.
The following specifications apply to filter interface modules implemented before January 2012.
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 com-
ponent tolerance. On average, the output power decreases
as the temperature is increased by a factor 1dB / 5°C.
