There are 3 fiber spans over 130 km between trx Lannion_CAS and trx Lorient_KMA

Now propagating between trx Lannion_CAS and trx Lorient_KMA:
Reference used for design: (Input optical power reference in span = 0.00dBm,
                            spacing = 50.00GHz
                            nb_channels = 76)

Channels propagating: (Input optical power deviation in span = 0.00dB,
                       spacing = 50.00GHz,
                       transceiver output power = 0.00dBm,
                       nb_channels = 76)
