Notes: 1.Power-on Initialization Time is the time from when the power supply voltages reach and remain above the minimum recommended operating supply voltages to the time when the module is fully functional. 2. The single ended input voltage tolerance is the allowable range of the instantaneous input signals. 3. The maximum transmitter average optical power of 1.0 dBm is well within the guardband of receiver overload specifications of commercially available 10GBASE-SR SFP+ transceivers. 4. Even if the TDP < 0.9 dB, the OMA min must exceed the minimum value specified here

Notes:
- The receiver shall be able to tolerate, without damage, continuous exposure to a modulated optical input signal having this power level on one lane. The receiver does not have to operate correctly at this input
- Measured with conformance test signal at receiver input for BER = 1×10-12.
- Vertical eye closure penalty and stressed eye jitter are test conditions for measuring stressed receiver They are not characteristics of the receiver.
