Optical Characteristics

Minimum and maximum values specified over operating case temperature range at 50% duty cycle data signal.

Typical values are measured at room temperature unless otherwise noted.

Table 4. OC-48/STM-16 Transmitter Optical Characteristics (Tc = 0 °C to 65 °C)

1. Output power definitions and measurements per ITU-T Recommendation G.957.

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

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

conditions.

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

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

6. ITU-T Recommendation G.957, Optical Interfaces for Equipment and Systems Relating to the Synchronous Digital Hierarchy.
