Summary

Recommendation ITU-T G.696.1 provides physical layer specifications for intra‑domain (IaD) DWDM optical networking applications. Longitudinally compatible applications inside a single administrative domain are described for point-to-point, multichannel line systems with or without line amplifiers. The application codes in this Recommendation provide a set of categories for DWDM transmission systems and fibre links. The primary purpose is to enable multiple vendors to design DWDM transmission equipment for fibre links that are compliant with this Recommendation.

In this version of this Recommendation, the following topics have been added with respect to the version from 07/2005:

•            Client class 100G;

•            Additional text for clause 8 "Optical safety considerations";

•            Comprehensive revision of Appendix I including new clauses I.2.6, I.3.6, I.3.7, I.4, I.5 and additional text for some clauses.
