WDM meansWavelength Division Multiplexing

CWDM – Coarse Wavelength Division Multiplexing- Spacing of 20nm - A 1620nm 1260nm band - Maximum capacity of 16 channels / lambda

DWDM – Dense Wavelength Division Multiplexing (Até 160 Lambdas)

- Spacing of 0.80 nm (100GHz) or 0.40 nm (50GHz) - Bands from 1529.16 nm to 1603.57 nm (Band C Band

and L) - Maximum capacity of 160 channels / lambda

Band C (from 1529.55 nm to 1560.61 nm)

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.
