scope:

This Recommendation specifies a physical layer for dense wavelength division multiplexing (DWDM) applications in point-to-point repeatered optical fibre submarine cable systems. The goal is to enable transversally compatible applications.

The primary purpose is to enable multiple vendors to provide terminal equipment for submarine fibre links that are compliant with this Recommendation.

This Recommendation includes a generic reference model for physical layer applications. The specifications take into account parameters such as maximum attenuation, fibre types, wavelength ranges, maximum chromatic dispersion (CD), minimum local CD coefficient, maximum differential group delay (DGD) and effective area.

This Recommendation focuses on repeatered optical fibre submarine cable systems without CD management.

This Recommendation presumes that the optical tributary signals transported within optical channels are digital.

This Recommendation covers a multiple-link partial transverse compatible repeatered optical fibre submarine cable system, where all the submerged plant is provided by a single vendor for all fibre pairs, while the terminal equipment at either end of the link may be provided by a different vendor. A full transverse compatible system, where different types of submerged equipment are provided by different vendors from its terminating equipment, lies outside the scope of this Recommendation.
