• The Recommendation on SM Test Methods was subdivided into three smaller Recommendations:– G.650.1 Definitions and test methods for linear, deterministic

attributes (consented)– G.650.2 Definitions and test methods for statistical and non-linear

attributes (consented)– G.650.3 Test methods for installed single-mode links (under

discussion)

• 40 GB/s applications facilitate PMD Discussions– PMDQ values Correspondence Group

• New fiber type - Draft Recommendation G.scl– Non-zero dispersion-shifted fiber that would operate in the S, C, and L

bands– Correspondence Group preparing a draft for the next mtg.
