Note1. The supply current is SFP module’s working current. Note2: For the measurements, the device was driven with 1.25Gbps data pattern with 2 7-1 PRBS payload Note3. Optical transition time is the time interval required for the rising or falling edge of an optical pulse to transition between the 20% and 80% amplitudes relative to the logical 1 and 0 levels Note4. Measured with a PRBS 2 7-1 test pattern, @1.25Gbps, EX=10dB, BER<10 -12 Note5. The LOS Hysteresis to minimize ―chatter‖ on the output line. In principle, Hysteresis alone does not guarantee chatter-free operation
