3. Current Optical Fiber & Cable Activities (SG15)
The Recommendation on SM Test Methods was subdivided into three smaller Recommendations:
G Definitions and test methods for linear, deterministic attributes (consented)
G Definitions and test methods for statistical and non-linear attributes (consented)
G Test methods for installed single-mode links (under discussion)
40 GB/s applications facilitate PMD Discussions
