Notes:
1. Coupled into LC fiber. 
2. 10Gb/s ,PRBS31,Specifications 10-12BER.
3. As measured using Digital Diagnostics capability.
4. Power1 is set at -10dBm,Power2 is set at -15dBm,Power3 is set at -20dBm;
Extinction Ratio was measured with an Agilent 86105A option.
 
To verify compliance with specification, eleven modules were tested beyond the full operational range of voltage(3.13V to 3.47V).The temperature listed(case -40℃ to 85℃) are industrial temperatures. Modules were tested at all corner cases of operating voltage and industrial temperature. The resulting test data is summarized in the following figures.
 
 
 
Eyediagram Under 3 Temperatures
 
Figure 1
The module is operated at f=10Gb/s, PRBS31, 3.3V. The trace shows a typical Tx eye at -40℃ 

 
Figure 2
The module is operated at f=10Gb/s, PRBS 31, 3.3V. The trace shows a typical Tx eye at 25℃.
 
 
Figure 3
The module is operated at f=10Gb/s, PRBS 31, 3.3V. The trace shows a typical Tx eye at 85℃.
