1 Scope
This part of IEC 61753
contains the minimum initial test and measurement requirements and severities which
a fibre optic middle-scale 1 × N (16 ≤ N ≤ 64) DWDM (dense wavelength division multiplexing) arrayed waveguide grating device
with channel spacing of 50 GHz, 100 GHz or 200 GHz satisfies in order to be categorized
as meeting the requirements of category OP (outdoor protected environment). The requirements
are given for the DWDM devices with Gaussian passband profile and flat-top passband
profile. The requirements exclude the devices with dynamic electrical temperature
control.
