11 The Insertion Loss (IL) values are measured as the maximum IL inside the Operating Wavelength Bandwidth (± 80 pm, centered on each ITU wavelength of
the channel).
12 Insertion Loss Uniformity is defined as the difference between the maximum insertion losses over any two operating wavelength bandwidths.
13 Adjacent Channel Isolation is defined as the difference between the maximum IL in the 100 GHz transmitted channel Bandwidth (ITU ± 80 pm) and the
13 Adjacent Channel Isolation is defined as the difference between the maximum IL in the 100 GHz transmitted channel Bandwidth (ITU ± 80 pm) and the
minimum IL measured over the Operating Wavelength Bandwidth of both adjacent 100 GHz channels.
14 Non-Adjacent Channel Isolation is defined as the difference between the maximum IL in the 100 GHz transmitted channel Bandwidth (ITU ± 80 pm) and the
minimum IL measured over the Operating Wavelength Bandwidth of both non-adjacent 100 GHz channels.
15 The difference between the maximum and minimum group delay in the Operating Wavelength Bandwidth of each channel evaluated at all SOP.
16 Chromatic Dispersion is defined as the maximum derivative of the Group Delay versus the wavelength curve in the 100 GHz transmitted channel bandwidth

(Operating Wavelength Bandwidth)
17 PDL (Polarization Dependent Loss) is defined as the difference between the maximum and minimum IL in the 100 GHz transmitted channel Bandwidth
(Operating Wavelength Bandwidth) evaluated at all SOP, measured at a given wavelength.
18 PMD (Polarization Mode Dispersion) is defined as the maximum of the DGD versus the wavelength curve in the 100 GHz transmitted channel bandwidth
(Operating Wavelength Bandwidth).
19 Mux Module: Attenuation = IL1 - IL2, where IL1 = Ch1-RX to MON-MUX Insertion Loss and IL2 = Ch1-RX to COM-TX Insertion Loss.
20 Demux Module: COM-RX to MON-DMX Insertion Loss.
