1550 nm Laser, Single mode +5 dBm –30 dBm 35 dB –14 dBm
The power budgets are calculated from the manufacturer’s worst-case transmitter power and worst case receiver
sensitivity.
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 of 1 dB / 5 °C.
