TOPIC 4: Theory About Products Absolute Power x Power Surge Channel The absolute power in the common points of multiplexed channels varies in accordance with the number of channels. This approach is represented by the following formula :

Pabs(dBm) = Pch(dBm) + 10 x log(Nch)

onde: Pabs(dBm)  Absolute Power (measured by power meter or T2000) Pch(dBm)  Peak power of the channel (measured with OSA) Nch  Number of Channels Trecho.

Exemplo Real: During deployment of the stretch between HDPE and SPO-BRE-TRM was measured using the management T2000 power values described below in Figure Using as starting input power station SPO-IPCC calculating the peak power of channel would be: -18,60dBm = Pch(dBm) + 10 x log (2) Pch(dBm) = - 21,60dBm On receipt of SPO-IPCC is a UFO. According to manufacturer the peak power channel to be-22dBm ± 1dB.
