Notes:

1. The optical power is launched into 50/125µm MMF.

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 223-1est pattern @1.25Gbps.

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