Notes: 

1. The optical power is launched into 9/125?m SMF. 

2. Unfiltered, measured with a PRBS 223-1 test pattern @1.25Gbps 

3. Meet the specified maximum output jitter requirements if the specified maximum input jitter is present. 

4. Measured with a PRBS 223-1 test pattern @1.25Gbps. 

5. Measured with a PRBS 223 -1 test pattern @1.25Gbps, worst-case extinction ratio, BER ≤1×10-10
