Standards Development
This part of IEC 61753 contains the minimum initial test and measurement requirements and severities which a fibre optic C-band/L-band WWDM device shall satisfy in order to be categorised as meeting the IEC standard, Category C – indoor controlled environment. The requirements cover devices with single-mode non-connectorised pigtails.
C-band/L-band WWDM devices combine and / or split C band and L band optical signals. A guard band is required between the used wavelength in the C and L band.
Commercially available C-band/L-band WWDM devices have narrower wavelength ranges such as 1 530 nm to 1 564 nm for C-band and 1 574 nm to 1 625 nm for L-band, compared with ITU-T Supplement N.39 Definitions, 1 530 nm to 1 565 nm for C-band and 1 565 nm to 1 625 nm for L-band. This standard describes performance standards for commercially available C-band/L-band WDM devices.
