1. Output power definitions and measurements per proposals to the ITU-T Recommendation G.691.

2. Full spectral width measured 20 dB down from the maximum of the central wavelength peak under fully modulated conditions.

3. Ratio of the peak output power in the dominant longitudinal mode to the power in the most significant side mode under fully modulated condi-

tions.

4. Ratio of logic 1 output power to logic 0 output under fully modulated conditions.

5. GR-253-CORE, Synchronous Optical Network (SONET) Transport Systems: Common Generic Criteria.

6. ITU-T Recommendation G.691, Optical Interfaces for Equipment and Systems Relating to the Synchronous Digital Hierarchy.

7. The 10 Gbits/s mask has not been currently agreed to by the standards committee. Proposal is to use the 2.5 Gbits/s SONET eye mask test

scaled to 10 Gbits/s. The inner mask will be met, however, the outer mask will not be met.
