Frequency
Dependence of Parameters
•Many optical
parameters can exhibit significant variation
over frequencies of interest to the network
these may include:
–Channel insertion loss
deviation (dB, Max)
–Channel chromatic
dispersion (ps/nm, Max, Min)
–Channel uniformity
(dB, Max)
–Insertion loss
(dB, Max, Min)
–Channel extinction
(dB, Min)
–Channel
signal-spontaneous noise figure (dB, Max)
–Channel gain (dB, Max,
Min)
–Others TDB in
conjunction with ITU-T Q6/15
