Data Sheet
1241/1243/1245-Type Uncooled Laser Transmitter
September 1999
Characteristics (continued)
Table 3. Optical Characteristics
1. Output power denitions and measurement per ITU-T Recommendation G.957 and G.958.
2. Ratio of logic 1 to logic 0 power levels.
3. Between 10% and 90% (50% duty cycle).
4. Root-mean-square spectral width accounts for modes up to and including those 20 dB down from the central mode.
(Applies to 1241-Type only.)
5. Applies to 1243/1245-Type only.
Recommended User Interfaces
1-496(C).c
* Locate these components as close to DATA/DATA inputs as possible.
Note: The 1241 gigabit version does not require the external 50
terminations since this termination is included inside the module.
