820 nm LED, Multimode –20 dBm
1300 nm LED, Multimode –21 dBm
1300 nm ELED, Single mode –23 dBm
1300 nm Laser, Single mode –1 dBm
1550 nm Laser, Single mode +5 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.

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