Summary

Recommendation ITU-T G.973.1 provides physical layer specifications for dense wavelength division multiplexing (DWDM) applications for repeaterless optical fibre submarine cable systems. Longitudinally compatible applications for DWDM applications for repeaterless optical fibre submarine cable systems are described for point-to-point, multichannel line systems without remotely pumped optical amplifiers. The primary purpose is to enable multiple vendors to design DWDM transmission equipment for submarine fibre links that are compliant with this Recommendation.
